Supplemental schedule of noncash investing and financing activities:

During January 2002, the Company acquired 100% of the outstanding capital stock of Aviron through an exchange offer and merger
transaction.  The Company exchanged approximately 34.0 million of its common shares for all of the outstanding shares of Aviron
common stock and assumed Aviron's outstanding options and warrants, for which approximately 7.0 million additional shares of the
Company's common stock are issuable.  The estimated fair value of the net assets acquired was $1,635.1 million, and included
$1,179.3 million of acquired research and development assets that were charged to current period results at the date of
acquisition and $211.4 million of 5 1/4% convertible subordinated notes due in 2008.

                       The accompanying notes are an integral part of these consolidated financial statements.




                                                           MEDIMMUNE, INC.
                                             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                                            (UNAUDITED)


General
The financial information presented in the consolidated financial statements at September 30, 2002 and for the three months and
nine months ended September 30, 2002 and 2001 is unaudited.  In the opinion of the Company's management, the financial information
presented herein contains all adjustments (which consist only of normal recurring adjustments) necessary for a fair presentation
of results for the interim periods presented.  Interim results are not necessarily indicative of results for an entire year or for
any subsequent interim period.  These consolidated financial statements should be read in conjunction with the Company's annual
report on Form 10-K for the year ended December 31, 2001.

Organization
MedImmune, Inc., a Delaware corporation (together with its subsidiaries, the "Company"), is a biotechnology company headquartered
in Gaithersburg, Maryland.  The Company currently actively markets three products, Synagis, Ethyol, and CytoGam, and maintains a
diverse research and development pipeline.  The Company is focused on developing important new products that address significant
medical needs in the areas of infectious diseases, immunology and oncology.

During January 2002, the Company completed its acquisition of Aviron, subsequently renamed MedImmune Vaccines, Inc., a
biopharmaceutical company headquartered in Mountain View, California, through an exchange offer and merger transaction (the
"Acquisition").  The Acquisition was accounted for as a purchase, and the results of operations of MedImmune Vaccines are included
in the results of the Company effective January 10, 2002.

Seasonality
The Company's largest product, Synagis, is used to prevent respiratory syncytial virus ("RSV") in high-risk infants.  RSV is most
prevalent in the winter months in the northern hemisphere.  Because of the seasonal nature of RSV, limited sales, if any, of
Synagis, are expected during the second and third quarters of any calendar year, causing results to vary significantly from
quarter to quarter.

Reclassification
Certain prior year amounts have been reclassified to conform to the current presentation.

New Accounting Standard
Effective January 1, 2002, the Company adopted SFAS No. 142 ("SFAS 142"), "Goodwill and Other Intangible Assets."  Inasmuch as the
Company had no recorded goodwill or intangible assets prior to the January 2002 acquisition of Aviron, the adoption of SFAS 142
did not have an impact on the Company's financial position, results of operations, or cash flows.

Change in Accounting Method
For new contracts executed or acquired after January 1, 2002, the Company has changed its accounting method for contract revenues
such that the Company may recognize contract revenues associated with substantive at-risk performance milestones when the
milestone is achieved, when no future service obligation is attendant to that milestone and when the related revenue is due and
payable under the milestone payment method. The change in accounting principle was made to more closely reflect the essence of the
Company's contractual obligations with collaborative partners.  Also, the new method is prevalent in the industry in which the
Company operates. The effect on earnings and earnings per share for the three months and nine months ended September 30, 2002 is
not material.

Significant Accounting Policies
Contract Revenues - For contracts executed prior to January 1, 2002, contract revenues are recognized during each period based on
a percentage-of-completion model based on actual costs incurred relative to the total projected costs.  Upfront fees and milestone
payments under collaborative agreements are recognized when they are earned in accordance with the applicable performance
requirements and contractual terms, using the contingency-adjusted performance (percentage-of-completion) model.  Under this
method, payments received that are related to future performance are deferred and recorded as revenues as they are earned over
specified future performance periods.  Recognized revenues are subject to revisions as the collaboration efforts progress and
estimated costs to complete are revised.

For new contracts executed or acquired after January 1, 2002, the Company uses the milestone payment method when all milestones to
be received under contractual arrangements are determined to be substantive, at-risk and the culmination of an earnings process.
Substantive milestones are payments that are conditioned upon an event requiring substantive effort, when the amount of the
milestone is reasonable relative to the time, effort and risk involved in achieving the milestone and when the milestones are
reasonable relative to each other and the amount of any up-front payment.  If all of these criteria are not met, then the Company
will use the contingency-adjusted performance model.

Acquisition
On January 10, 2002, the Company completed the Acquisition through an exchange offer and merger transaction.  MedImmune Vaccines
focuses on preventing disease through innovative vaccine technologies.  Its lead product candidate is FluMist, a live, attenuated
virus vaccine delivered as a nasal mist for the prevention of influenza.  FluMist has not been approved by the FDA.

Under the terms of the agreement, the Company exchanged approximately 34.0 million of its common shares for 100% of the
outstanding common stock of Aviron.  Additionally, approximately 7.0 million shares are issuable upon the exercise of Aviron's
outstanding options and warrants.  Holders of Aviron's $200 million of 5 1/4% convertible subordinated notes due in 2008 (the
"Notes") may convert the Notes into a total of approximately 3.4 million shares of the Company's common stock, based on a
conversion price of $58.14 per share.

The Acquisition was accounted for as a purchase and, accordingly, the results of MedImmune Vaccines' operations have been included
with the Company's operations since January 10, 2002.

In the nine-month period ended September 30, 2002, the Company recorded adjustments to the purchase price resulting from a final
reconciliation of Aviron registered shares of common stock as of the acquisition date, a refinement to the calculation of unearned
compensation for terminated employees, and a reconciliation of transaction costs.  The purchase price adjustments resulted in a
net decrease of $1.3 million to the purchase price and a corresponding decrease to goodwill.  The revised aggregate purchase
consideration was approximately $1.6 billion, as follows (in millions):

         Common stock                                                $1,497.3

The value of common shares issued was $44.10 per share, based on the closing market price of the Company's common stock on
November 30, 2001, the last business day prior to the signing of the merger agreement.  The fair value of Aviron's options and
warrants assumed in the transaction was estimated using the Black-Scholes option pricing model.

The following table summarizes the estimated fair values (in millions) of the assets acquired and liabilities assumed at the date
of acquisition, as revised.  The Company is in the process of determining the fair value of certain tangible assets and
liabilities; thus, the allocation of the purchase price is subject to refinement:

Intangible Assets - Of the $129.0 million of acquired intangible assets, $90.0 million was assigned to Aviron's worldwide
collaborative agreement with Wyeth for the development, manufacture, distribution, marketing, promotion, and sale of FluMist,
which is subject to amortization over its estimated useful life of approximately 11 years.  The Company estimated the fair value
of the Wyeth agreement using the sum of the probability-adjusted scenarios under the income approach.  In applying this method,
the Company relied on revenue assumptions, profitability assumptions and anticipated approval dates.  The remaining $39.0 million
was assigned to Aviron's contract manufacturing agreement with Evans Vaccines Limited, which is subject to amortization over its
estimated useful life of approximately four years.  The Company estimated the fair value of the Evans agreement using the cost
approach, which is based on the theory that a prudent investor would pay no more for an asset than the amount for which the asset
could be replaced.  In its analysis, the Company reduced replacement cost for such factors as physical deterioration and
functional or economic obsolescence.

In-Process Research and Development - Approximately $1,179.3 million of the purchase price was allocated to acquired research and
development assets that were written off at the date of acquisition as a separate component of the Company's results of operations
in accordance with FASB Interpretation No. 4, "Applicability of FASB Statement No. 2 to Business Combinations Accounted for by the
Purchase Method."  The amount represents the fair value of purchased in-process technology for projects, principally FluMist,
that, as of the date of the acquisition, had not yet reached technological feasibility and had no alternative future use.

Goodwill - Approximately $15.0 million in goodwill was recognized in the revised allocation of the purchase price, none of which
is expected to be deductible for tax purposes.  Through September 30, 2002, the Company recorded net purchase price adjustments of
$1.3 million, net reversals to the restructuring liability of less than $0.1 million (discussed below), and a $0.7 million
reduction to the fair value assigned to certain depreciable assets based on a final assessment of their net realizable value,
which in the aggregate resulted in a reduction to goodwill of $0.7 million.  In accordance with SFAS 142, the goodwill recognized
in the transaction is not amortized, but will be reviewed for impairment on an annual basis.

Restructuring Liability - Included in the revised allocation of acquisition cost is a restructuring liability of $16.0 million for
estimated costs associated with the Company's restructuring plan.  The restructuring plan was originally formulated and announced
to employees in December 2001, to consolidate and restructure certain functions, including the involuntary termination of eight
Aviron executives and 52 other Aviron employees from various functions and levels.  Through September 30, 2002, the Company
recorded purchase accounting adjustments resulting from a refinement to the calculation of involuntary termination benefits, the
removal from the original accrual of three positions that were retained, and to reflect revised costs estimated for vacant lease
space.  As a result of these adjustments, the Company recorded net restructuring charge reversals of less than $0.1 million
through September 30, 2002, which resulted in a corresponding reduction to goodwill.  Subsequent adjustments to the allocation of
the acquisition cost related to the true-up of severance and other restructuring costs, if any, are not expected to be
significant.  During the three months ended September 30, 2002, there were no significant amounts charged against the
restructuring liability for actual severance payments or compensation expense for the accelerated vesting of stock options for
terminated executives and employees, and rent expense of $0.2 million for vacant lease space was charged against the restructuring
liability.

The restructuring liability activity through September 30, 2002 is summarized as follows (in millions):

Transaction Costs - Included in the allocation of acquisition costs were accrued transaction costs of $9.8 million, which
primarily consist of investment banking, accounting and legal fees incurred by the Company.  For the period ended September 30,
2002, there were no significant adjustments to accrued transaction costs and all costs have been paid.

Pro Forma Data - The following unaudited pro forma condensed combined supplemental data present the revenues, net earnings and
earnings per share of the combined entity as though the business combination had been completed as of January 1, 2002 and 2001,
respectively.  The unaudited pro forma condensed combined supplemental data gives effect to actual operating results prior to the
acquisition, adjusted to include the pro forma effect of amortization of intangibles, deferred stock compensation costs, the
elimination of the non-recurring charge for acquired in-process research and development, the tax effects to the pro forma
adjustments and the recognition of the tax benefits arising from Aviron's net loss for the 2001 period.  The unaudited pro forma
condensed combined supplemental data are not necessarily an indication of the results that would have been achieved had the
transaction been consummated as of the dates indicated or that may be achieved in the future (in millions, except per share
data).

(1) Excludes a non-recurring charge of $1,179.3 million for acquired in-process research and development.

Long-term Debt
Following the Acquisition, the Company's wholly owned subsidiary, MedImmune Vaccines Inc., remains obligated for its outstanding
indebtedness, which includes $200.0 million aggregate principal amount of the Notes.  Approximately $211.4 million of the
acquisition cost was allocated to the Notes, which represents the fair value as of the acquisition date, based on quoted market
prices.  The Notes are convertible into an aggregate of 3.4 million shares of the Company's common stock, based on a conversion
price of $58.14, at any time on or before January 15, 2008.  MedImmune Vaccines may redeem the Notes beginning in February 2004,
at redemption prices declining from 103% of their principal amount in 2004 to 100% in 2008, plus accrued interest.  Interest is
payable semi-annually in arrears in cash on February 1 and August 1 each year.

Derivative Instruments and Hedging Activities
The Company adopted SFAS 133, "Accounting for Derivative Instruments and Hedging Activities," on January 1, 2001.

The Company accounts for its Euro-denominated foreign currency forward-exchange contracts as foreign currency cash-flow hedges and
is required to recognize any ineffectiveness on hedging transactions as interest income or expense in the statement of
operations.  For the three months and nine months ended September 30, 2002, gains or losses for ineffective hedges were
insignificant.  As of September 30, 2002, net deferred gains on derivative instruments of $0.3 million, net of tax, in accumulated
other comprehensive income are expected to be reclassified to earnings in the next 12 months in conjunction with the sale of the
related inventory.  The maximum term over which the Company is hedging its exposures to the variability of cash flows is 12 months.

During the third quarter of 2002, the Company entered into foreign currency forward-exchange contracts to purchase 12.5 million
British Pounds (GBPs) to fund construction payments denominated in GBPs.  The contracts were designated as cash flow hedges.
During the third quarter of 2002, the hedges were determined to be ineffective, and realized gains on the contracts were recorded
to the income statement in the amount of $0.3 million.  During October 2002, the contracts were subsequently cancelled, at an
immaterial loss to the Company.

Inventory
Inventory, net of reserves, is comprised of the following (in millions):

                                        9/30/02              12/31/01

                                         ======                =====

Noncurrent inventory at September 30, 2002 and December 31, 2001 is comprised of some of the Company's raw plasma and certain
CytoGam production lots that are being tested for long-term stability which are not expected to be available for sale within the
next 12 months.

Inventory balances are net of reserves for RespiGam inventory, for which minimal product sales are expected to result for the
foreseeable future.  In April 2002, the Company reduced the inventory and reserve balances by $3.4 million upon the disposal of
expired product.  RespiGam inventory and reserve balances were $1.7 million and $0.6 million, respectively, at September 30, 2002,
versus $4.9 million and $4.2 million, respectively, at December 31, 2001.

The Company has commenced production of inventory in connection with its proposed launch of FluMist, which has not yet been
approved by the FDA.  The Company recorded a full reserve for such inventory produced through September 30, 2002, which resulted
in a year-to-date charge to other operating expense of approximately $39.4 million, in recognition of management's assessment that
it currently appears probable that such inventory materials will reach their expiration dates as FDA approval, if it occurs, is
not expected until 2003.

Earnings per Share
The Company computes earnings per share in accordance with Statement of Financial Accounting Standards No. 128, "Earnings Per
Share."  Basic earnings per share is computed based on the weighted average number of common shares outstanding during the period.
Diluted earnings per share is computed based on the weighted average shares outstanding adjusted for all dilutive potential common
shares.  The dilutive impact, if any, of common stock equivalents outstanding during the period, including outstanding stock
options and warrants, is measured by the treasury stock method.  The dilutive impact, if any, of the Notes is measured using the
if-converted method.  Common stock equivalents are not included in periods where there is a loss as they are anti-dilutive.  The
following is a reconciliation of the denominator of the diluted EPS computation for the periods reported (in millions).  There are
no reconciling items to the numerator for the EPS computation for the periods reported.

Options to purchase 6.7 million shares of common stock with prices ranging from $39.87 to $83.25 per share that were outstanding
during the nine months ended September 30, 2001 were not included in the computation of diluted earnings per share because they
were anti-dilutive.

Income Taxes
Income tax benefit for the three months and nine months ended September 30, 2002 was $20.1 million and $1.7 million,
respectively.  Excluding the Company's write-off of purchased in-process research and development and other insignificant items,
which are not tax deductible, income tax expense as a percentage of pre-tax income for the nine months ended September 30, 2002
was 35%.  During the nine months ended September 30, 2002, the Company recognized credits for research and development
expenditures and credits earned for "Orphan Drug" status of certain research and development expenses, resulting in a reduction
from the statutory rate of 37.0%.

Comprehensive Income
Comprehensive income is comprised of net earnings or loss and other comprehensive income. Other comprehensive income includes
certain changes in equity that are excluded from net earnings or loss, such as translation adjustments, unrealized holding gains
and losses on available-for-sale marketable securities, and gains and losses on hedging instruments.

Comprehensive loss for the three months ended September 30, 2002 was $25.2 million versus $10.1 million for the comparable period
in 2001.  Comprehensive (loss) income for the nine months ended September 30, 2002 was $(1,171.6) million versus $55.5 million for
the comparable period in 2001.  Net unrealized holding gains on available-for-sale marketable securities of $11.1 million and $8.6
million for the three months ended September 30, 2002 and 2001, respectively, and $10.3 million and $5.3 million, respectively,
for the nine months ended September 30, 2002 and 2001 were a significant component of comprehensive income during those periods.

Minority Interest Investments
In connection with its research and development collaborations, the Company holds minority interests in companies having
operations or technology in areas within its strategic focus.  The investments are maintained on the cost or equity method of
accounting, according to the facts and circumstances of the individual investment.  Under either method, the investments are
subject to adjustment for other-than-temporary impairments.   Additionally, for investments carried on the equity method, the
Company's proportionate share of the investee's gains or losses is recorded on a quarterly basis.  For minority interests
maintained in publicly traded companies, the Company's investment is maintained as available-for-sale securities.  Due to the
highly volatile share prices of these investments, the investments are subject to unrealized holding gains or losses.

As of September 30, 2002, the Company determined that the declines in fair value below the cost basis of certain of its minority
interest investments were other than temporary, based primarily on the duration and magnitude of the declines in fair value,
largely due to the downward movement in the capital markets, as well as the financial condition and near-term prospects of the
investee companies.  For the three months and nine months ended September 30, 2002, the Company recorded realized losses of $10.3
million and $10.6 million, respectively, to write-down the cost basis of certain of its minority interest investments to fair
value.

Property and Equipment
During March 2002, the Company paid approximately $13.4 million to acquire 11 acres of land in Gaithersburg, Maryland, which will
serve as the site of the Company's new corporate headquarters.  Additionally, the Company has options to purchase an additional 14
acres of land.  The Company has begun construction of the first phase of the new facility, at a total estimated cost of $85
million.  As of September 30, 2002, approximately $8.8 million of engineering and construction costs related to Phase I of the new
headquarters are included in construction in progress.  The Company expects to take occupancy of the first phase of construction,
which will feature a complex totaling approximately 220,000 square feet, in the fall of 2003.

Collaborative Arrangements
Wyeth
In January 1999, Aviron signed a worldwide collaborative agreement with Wyeth Lederle Vaccines, a subsidiary of Wyeth, for the
development, manufacture, distribution, marketing, promotion, and sale of FluMist.  Under this agreement, Wyeth has exclusive
worldwide rights to market FluMist, excluding Korea, Australia, New Zealand and some South Pacific countries.  The two companies
have agreed to co-promote FluMist in the United States, with the Company focusing on non-traditional channels.  Wyeth holds the
marketing rights in the United States for an initial term of seven years from the first commercial sale of FluMist in the United
States.  Outside the United States (with the exclusions noted above), Wyeth holds the marketing rights for an initial term of
eight years from the first commercial sale of FluMist outside the United States.  Wyeth has the option to extend its rights both
in the United States and internationally for an additional four years, the aggregate of which could result in payments to the
Company ranging from $145 million to $400 million.  Under the terms of the agreement with Wyeth, the two companies are to
collaborate on the regulatory, clinical and marketing programs for FluMist within the United States.

As a part of the collaboration, the Company is to receive certain payments related to the achievement of key milestones and events
for FluMist.  In January 2001, Aviron received from Wyeth: $15.5 million related to the acceptance by the FDA of the filing of the
Biological License Application ("BLA") for FluMist on December 28, 2000; and $10.0 million as compensation for manufacturing costs
incurred in preparing for the then-expected 2001 FluMist launch.  Under the agreements, as recently amended, potential milestones
and related payments to the Company from Wyeth include:  $25 million as compensation for manufacturing costs incurred in preparing
for the potential, but now not expected, 2002 FluMist launch; $20 million for FDA approval in the United States; $20 million for
advisory body recommendations and expanded label claims; up to $25 million in supply goal payments; up to $17.5 million for FDA
approval of use in multiple target populations; $10 million for the submission of a license application in Europe;  $27.5 million
for FDA approval of a liquid formulation of FluMist; and up to $50 million upon licensure in international regions.  Additionally,
Wyeth is committed to provide the Company with up to $20 million in financing, contingent upon regulatory approval of FluMist.
The total potential value for the license fees, milestones, financing support and term extension options that the Company could
receive from Wyeth could range from approximately $320 million to $620 million.

Under the terms of the agreement, Wyeth will distribute FluMist and record all product sales. The Company will receive
approximately 50% of FluMist revenues, paid in the form of product transfer payments and royalties.  These payments are higher in
the United States than internationally.  The Company incurs expenses to manufacture, supply and co-promote FluMist.  There is
potential for the manufacturing cost incurred by the Company to exceed transfer payments received from Wyeth.  Wyeth reimburses
the Company for a portion of the product's clinical development and sales and marketing expenses, and has agreed to spend up to
$100 million over the first three years for commercialization of FluMist in the United States.

Evans Vaccines Limited
In July 1999, Aviron entered into an agreement with a division of Celltech Group Plc, which was later acquired by PowderJect
Pharmaceuticals Plc and is now called Evans Vaccines Limited ("Evans"), for the manufacture of key components of FluMist,
specifically the bulk manufacture of monovalents and diluent, as well as use of the manufacturing facilities.  During October
2000, Aviron restructured its agreement with Evans in order to gain direct control over FluMist manufacturing operations. Aviron
obtained responsibility for bulk manufacture of FluMist in Evans' Speke, U.K. facility, hired approximately 100 Evans employees
who had been working on FluMist, and entered into subleases through June 2006 for the FluMist manufacturing areas on the existing
site. In connection with the restructuring of the manufacturing agreement, Aviron made an initial payment of $15.0 million and
payments of $3.9 million in September 2001 and 2002.  The Company is obligated to make three additional annual payments of $3.9
million in September 2003 through September 2005, which is included in other liabilities in the accompanying consolidated balance
sheet as of September 30, 2002.  The Company is also obligated to make other additional payments totaling $19.0 million (included
in other liabilities in the accompanying consolidated balance sheet as of September 30, 2002), which will be paid over the term of
the agreement based on net sales of FluMist, if and when approved for marketing, with the unpaid balance, if any, due January
2006.  In addition, the Company is obligated to make payments during the term of the agreement of $225,000 per year for the use of
the Aviron unit in the Evans manufacturing plant, payments up to an aggregate of $3.0 million for attaining specific milestones,
and payments for other support services based on the costs of these services incurred. The Company expenses rent and other support
services as the costs are incurred, and expenses milestones as they become due.

Legal Proceedings
In 1998, MediGene AG ("MediGene") initiated a legal action against Loyola University of Chicago ("Loyola") and the Company in the
United States District Court for the Northern District of Illinois alleging, among other things, breach of contract and tortious
interference by the Company with an alleged prospective business relationship between MediGene and Loyola. The claims relate to
human papillomavirus vaccine technology allegedly covered by contracts between MediGene and the Company and by a license agreement
from Loyola to the Company, under which the Company granted a sublicense to GlaxoSmithKline.  MediGene seeks damages from the
Company ranging from $31.3 million to $86.9 million based on the tortious interference claim, and/or damages ranging from $10.2
million to $31.3 million based on the breach of contract claim.  MediGene also seeks ownership of the patents in question, as well
as rescission of the Company's license agreement from Loyola or rights as a third-party beneficiary thereof.  The District Court
has granted summary judgment in favor of the Company on all claims and MediGene has appealed.

In October 2000, Celltech Chiroscience Limited ("Celltech") commenced a legal proceeding against the Company in the U.K. High
Court of Justice, Chancery Division, Patents Court.  Celltech alleges that the Company failed to pay royalties with respect to its
sales of Synagis as required by a license agreement dated January 19, 1998.  Under the agreement, the Company obtained from
Celltech a worldwide license to make, use and/or sell product under a patent (and related applications) pertaining to humanized
antibodies.  In the proceeding, Celltech seeks payment of a 2% royalty based on net sales of Synagis sold or manufactured in the
United States, with interest, and certain costs, including attorney's fees.  The Company filed answering papers denying that any
royalties are due on the basis that Celltech's United States patent does not cover Synagis and has sought dismissal of the case on
the grounds that the legal doctrine of prosecution history estoppel prevents Celltech from claiming that its patent covers
Synagis. On October 28, 2002, the High Court of Justice ruled in favor of the Company and dismissed Celltech's case on this basis
after a hearing was held before the Court in early October 2002.  Celltech is expected to appeal.

On November 29, 2001, the Company received a letter from counsel for Celltech enclosing a copy of a patent granted by the European
Patent Office on November 14, 2001.  That letter requested various information concerning the manufacture and sale of Synagis in
Europe and sought confirmation that the Company would pay royalties on such sales pursuant to the license agreement dated January
19, 1998.  On September 16, 2002, Celltech (now known as Celltech R&D Limited) commenced a second legal proceeding against the
Company in the U.K. High Court of Justice, Chancery Division, Patents Court, based on the license agreement dated January 19,
1998.  Celltech seeks payment of a 2% royalty based on net sales of Synagis sold or manufactured in Germany after the effective
date of the patent (November, 2001), with interest and certain costs, including attorney fees.  The Company has a contract
manufacturing relationship with Boehringer Ingleheim (BI) for the manufacture of Synagis in Germany.  As of November 7, 2002, the
Company had not made the royalty payments that were the subject of Celltech's November 29, 2001 letter or its September 16, 2002
lawsuit.  The Company's answering papers are due on December 4, 2002.

On December 18, 2001, Genentech, Inc. ("Genentech") announced that it had been granted a patent relating to certain methods and
compositions used to produce antibodies by recombinant DNA technology.  In June 1997, in anticipation of any potential impact the
issuance of Genentech's patent could have on the production of Synagis, the Company obtained a license to this patent.  The
Company has received from Genentech a letter, dated January 7, 2002, stating that Genentech expects to receive from the Company
royalty payments pursuant to such license. The Company is in the process of evaluating whether any valid claim of Genentech's
patent, as recently issued, covers production of Synagis.  Pending resolution of this issue, the Company has made certain royalty
payments to Genentech under protest and with reservation of all of its rights.  The Company is also evaluating whether any of its
other antibody-based product candidates, if and when approved for marketing by the United States Food and Drug Administration,
could require a license under any valid claim of the Genentech patent.

On February 28, 1996, Ichthyol Gesellschaft Cordes, Hermanni & Co. ("Ichthyol Gesellschaft") filed a complaint for refrain,
information and damages with the Regional Court of Hamburg against MedImmune Oncology on the grounds of trademark infringement in
respect of the use of the trademark "Ethyol" in Germany.  No monetary amount is currently being sought in the litigation by
Ichthyol.  Ichthyol is seeking injunctive relief against the use of the trademark Ethyol in Germany.  The suit was dismissed on
January 29, 1997 by the Regional Court of Hamburg.  Ichthyol Gesellschaft filed an appeal and a judgment was rendered in favor of
MedImmune Oncology in the appellate proceedings.  In January 1999, Ichthyol Gesellschaft filed an appeal on points of law with the
Federal Court of Justice, and in June 1999, Ichthyol Gesellschaft filed the grounds for the appeal on points of law.  By judgment
of May 3, 2001, the Federal Court of Justice reversed the judgment of the Higher Regional Court and remitted the case to that
court for another hearing.  By order of December l9, 2001, the Higher Regional Court ordered Ichthyol to make further submissions
concerning the relevant facts and legal questions.  Ichthyol recently filed its submissions.  A hearing was held during the fall
of 2002.  No decision has been reached, but the parties are engaged in settlement discussions.

The Company has been involved in a contract dispute with the University of Massachusetts Biologic Laboratories ("MBL") regarding
the Company's agreement to transfer to MBL certain technology relating to the Company's monoclonal antibody manufacturing
operations.  During the third quarter of 2002, the parties agreed to a settlement of the dispute for a $5 million payment by the
Company, which was charged to the income statement.  The Company will also secure the return of the rights to "make, have made,
use and sell" the Company's monoclonal antibody for RSV in the Commonwealth of Massachusetts and State of Maine in exchange for a
royalty.

On April 5, 2002, the Company filed a suit against Centocor, Inc. ("Centocor") in the United States District Court for the
District of Maryland.  The Company currently pays Centocor a royalty for sales of Synagis made or sold in the United States
pursuant to a patent Sublicense Agreement between the parties dated as of September 15, 2000 (the "Sublicense Agreement").  In the
litigation, the Company seeks a declaratory judgment that it has no obligation to continue paying royalties to Centocor on the
basis that the patent is invalid, unenforceable and does not cover Synagis.  Additionally, the Company seeks an injunction
preventing Centocor from enforcing this patent.  On July 1, 2002, Centocor moved to dismiss this action on the basis that it did
not include the Trustees of Columbia University in the City of New York ("Columbia") and the Board of Trustees of the Leland
Stanford University ("Stanford"), as the owners of the patent.  The court has not yet issued its decision on Centocor's motion.
On July 9, 2002, Centocor, Columbia and Stanford initiated an action against the Company in the United States District Court for
the Northern District of California.  In the California litigation, Centocor, Columbia and Stanford sought a declaratory judgment
that the patent at issue in the Sublicense Agreement is valid and enforceable and that the Company would be liable for patent
infringement but for the Sublicense Agreement, as well as a declaratory judgment that the Sublicense Agreement is enforceable.
The Company moved to dismiss the California action, among other arguments, on the basis that a prior action was filed in the U.S.
District Court for the State of Maryland and the California action should not go forward.  On October 21, 2002, the court ruled in
favor of the Company and dismissed the California litigation.  There can be no assurance that the Company will be successful in
this dispute.
                                                    ----------------------------

After consultation with its counsel, the Company believes that it has meritorious defenses to the claims against it referred to
above and is determined to defend its position vigorously.  While it is impossible to predict with certainty the eventual outcome
of these proceedings, the Company believes they are unlikely to have a material adverse effect on its financial position but might
have a material adverse effect on its results of operations for a particular period.



ITEM 2.

                                              MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                                           FINANCIAL CONDITION AND RESULTS OF OPERATIONS


GENERAL

During January 2002, we acquired Aviron, a biopharmaceutical company focused on preventing disease through innovative vaccine
technologies. Aviron was subsequently renamed MedImmune Vaccines, Inc. We accounted for the acquisition under the purchase method
of accounting and have included MedImmune Vaccines' operating results in our consolidated operating results beginning January 10,
2002.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

For a more detailed discussion of our critical accounting policies and estimates, please refer to Part II, Item 7 "Management's
Discussion and Analysis of Financial Condition Results of Operations" in our 2001 Annual Report on Form 10-K.

Contract Revenues - For contracts executed or acquired prior to January 1, 2002, we recognize revenue from upfront and milestone
payments under collaborative agreements using the contingency-adjusted performance (percentage-of-completion) model.  Under this
method, payments received that are related to future performance are deferred and recorded as revenues as they are earned over
specified future performance periods.  The amount of revenue recognized during each period is based on actual costs incurred
relative to the total projected costs to be incurred.  When the performance criteria for a non-refundable milestone payment are
met, revenue is recognized for that milestone based on the proration of actual costs incurred relative to the total costs to be
incurred.  Recognized revenues are subject to revisions as the collaboration efforts progress and estimated costs to complete are
revised. Revisions in revenue estimates are recorded to income in the period in which the facts that give rise to the revision
become known.

For new contracts executed or acquired after January 1, 2002, the Company uses the milestone payment method when all milestones to
be received under contractual arrangements are determined to be substantive, at-risk and the culmination of an earnings process.
Substantive milestones are payments that are conditioned upon an event requiring substantive effort, when the amount of the
milestone is reasonable relative to the time, effort and risk involved in achieving the milestone and when the milestones are
reasonable relative to each other and to the amount of any up-front payment.  If all of these criteria are not met, then the
Company will use the contingency-adjusted performance model.  This constitutes a change in accounting principle and was made to
more closely reflect the essence of the contractual obligations the Company enters into with collaborative partners.  Since
milestone payments are often times directly related to the completed portion (an achieved milestone) of the arrangement, revenue
is earned and recognized as the milestones are achieved.  Additionally, the new method is prevalent in our industry and is used by
most other companies in our peer group.  The effect on earnings and earnings per share for the three months and nine months ended
September 30, 2002 is not material.  The milestone payment method may not be applicable to all new contracts, in which case the
Company would revert to the contingency-adjusted performance model for revenue recognition.

Research and Development-  We expense research and development expenses as they are incurred.  These expenses include related
salaries, contractor fees, building costs, utilities, and administrative expenses.

   Licensing Fees-  In the normal course of business, we enter into collaborative research and development and in-licensing
agreements to acquire access to technology.  These collaborative agreements usually require us to pay up-front fees and milestone
payments, some of which are significant.  When we pay an up-front or milestone payment, management evaluates the stage of the
acquired technology to determine the appropriate accounting treatment.  If the technology is considered to be in the early
development stage (generally defined as pre-clinical through Phase 1 (safety)), the up-front or milestone payment is expensed.  If
the technology has entered Phase 2 (efficacy) clinical trials but has not yet been approved by regulatory authorities, we will
evaluate the facts and circumstances of each case to determine if a portion or all of the payment have future benefit and should
be capitalized at fair value.  Payments made to third parties subsequent to regulatory approval will be capitalized with that cost
generally amortized over the patented life of the product.  The agreements may also require that we provide funding for research
programs of our partners.  These costs are expensed as incurred.

   Clinical Trials-  We accrue estimated costs for clinical and preclinical studies performed by contract research organizations or
by our own staff based on the total estimated cost of the trial and the estimated percentage of completion of the clinical trial
related activities.  These costs are a significant component of research and development expenses. We monitor the progress of the
trials and their related activities to the extent possible, and adjust our accruals accordingly.

Sales Reserves -  We continually monitor the need for reserves associated with potential bad debts, sales discounts, sales returns
and government rebates.  We establish these reserves based on analysis of the marketplace, credit risk and historical trends for
each product.  If the actual bad debts, discounts, returns or requests for rebates deviate from the historical data on which the
reserve has been established, our revenue could be affected.

Acquired In-Process Research and Development - We recorded a charge of $1,179.3 million during the nine-month period ended
September 30, 2002 for the write-off of purchased in-process research and development in conjunction with our acquisition of
Aviron.  The write-off represents the fair value of purchased in-process technologies at the acquisition date, calculated
utilizing the sum of the probability-adjusted scenarios under the income approach.  This method is based upon management's
estimates of the probability of FDA approval and commercial success for FluMist.  As with all biotechnology products, the
probability of FDA approval and commercial success for any particular research and development project is highly uncertain.
Management's projections were based on assumptions, which may or may not remain valid for the relevant period, including the
estimated impact of four "key" factors:  price per dose; dose volume; launch date; and the potential failure of the frozen or
liquid formulations of FluMist.  Based on current information, management believes that the estimates and assumptions underlying
the fair value analysis are reasonable.

Investments -   We regularly enter into collaborative research and development agreements with strategic partners.  As part of the
agreements, we may obtain common stock, preferred stock or other equity securities in these strategic partners.  These companies
may be public or privately held companies.  At the time the securities are obtained, we determine if the investment should be
accounted for under the cost method, equity method, or consolidation method based upon multiple factors including:  percentage
ownership of the company; representation on board of directors; participation in policy-making processes; technological
dependency; veto rights of partners; our role on key technical or product development committees; revenue dependence; and other
extraordinary voting rights.  Investments accounted for under the equity method are adjusted quarterly for the Company's
proportionate share of the investee's gains or losses, which may fluctuate significantly from quarter to quarter.  Each quarter,
we evaluate all of our investments, and recognize an impairment charge in the consolidated statements of operations when a decline
in the fair value of an investment falls below its cost value and is judged to be other than temporary.  We consider various
factors in determining whether we should recognize an impairment charge, including the length of time and extent to which the fair
value has been less than our cost basis, the financial condition and near-term prospects of the issuer, fundamental changes to the
business prospects of the investee, share prices of subsequent offerings, and our intent and ability to hold the investment for a
period of time sufficient to allow for any anticipated recovery in market value.

Inventory Reserves - The Company has commenced production of inventory in connection with its proposed launch of FluMist, which
has not yet been approved by the FDA.  The Company recorded a full reserve for such inventory produced from January 10, 2002
through September 30, 2002, which resulted in a charge to other operating expense of approximately $39.4 million, in recognition
of management's assessment that it currently appears probable that such inventory materials will reach their expiration dates as
FDA approval, if it occurs, is not expected until 2003.  Should FluMist be approved for some portion of the 2002/2003 flu season,
any inventory sold would have no carrying value and, as such, margins would be favorably impacted in those periods when the
related inventory was sold.

RESULTS OF OPERATIONS
THREE MONTHS ENDED September 30, 2002 AND 2001

Product Sales -


          Product Sales (In Millions)              2002           2001
                                                  -----          -----

          Synagis                                 $30.2          $30.0

          Ethyol                                  $20.2          $(0.4)

          Other Products                           $8.8          $10.4
                                                  -----          -----
          TOTAL                                   $59.2          $40.0


Product sales grew 48% to $59.2 million in the third quarter of 2002 compared to $40.0 million in the same period last year.  This
increase is attributable to the impact of reacquiring the domestic marketing rights to Ethyol as of October 1, 2001.

Synagis- We achieved a 19% increase in domestic Synagis sales to $25.8 million in 2002 from $21.7 million in 2001. This growth was
largely due to increased demand in the United States, and resulted in an 18% increase in domestic units sold. Also aiding growth was
a 3% price increase that took effect in June 2002. Our reported international sales of Synagis decreased 47% to $4.4 million in the
2002 quarter compared to $8.3 million in the 2001 quarter, due to a 51% decrease in units sold to Abbott International ("Abbott"),
our exclusive distributor of Synagis outside of the United States. We believe that the decrease is due to reductions in the
inventory stocking levels of Abbott, rather than reduced product demand by end users. The decrease in unit volume was offset by an
increase in the per unit sales price recognized upon delivery of product to Abbott under the terms of our international distribution
agreement. Based on information received from Abbott, we believe that end-user sales have increased over last year's comparable
quarter. We record Synagis international product sales based on Abbott's sales price to customers, as defined in the agreement. We
have been working with Abbott to expand the number of countries where we are licensed to sell Synagis. As of September 30, 2002,
international registrations have been filed in 58 countries for the approval of Synagis, for which approval in 50 countries,
including the United States, had been obtained, the most recent of which was Canada in May 2002. There can be no assurance that
approvals by the appropriate regulatory authorities will continue to be granted or that we will receive pricing and reimbursement
approvals in countries where we have received regulatory approval.

Ethyol-  On October 1, 2001 we reacquired domestic marketing rights to Ethyol from ALZA Corporation ("ALZA") and have since
recorded all revenues from domestic sales of Ethyol to wholesalers and distributors.  As part of this agreement, no third quarter
2001 supply sales were made to ALZA, and we purchased ALZA's remaining Ethyol inventory at their original purchase price, which
was recorded as a reduction to product sales.  Beginning April 1, 2002, we pay ALZA a declining royalty through 2011 based on net
sales of Ethyol in the United States.  Domestic Ethyol sales were $18.5 million in the 2002 quarter, as compared to net returns of
$2.3 million in the 2001 quarter.  Prior to October 1, 2001, we had recorded Ethyol domestic product sales based on ALZA's net
unit selling price as defined in the agreement.  Our international sales of Ethyol to our distribution partner, Schering-Plough
Corporation ("Schering"), of $1.7 million for the third quarter of 2002 were down slightly from the prior year quarter sales of
$1.9 million.  We record Ethyol international product sales based on Schering's end user sales, as defined in the agreement.

Other Products-  Sales of other products in third quarter 2002, which include sales of CytoGam, NeuTrexin, RespiGam, and
by-products that result from the CytoGam manufacturing process, decreased 12% to $8.8 million from $10.0 million in last year's
quarter.  The decrease was largely due to the 5% decline in CytoGam sales and a mix shift to more CytoGam international sales,
which sell at a lower unit price than domestic units.

Forward-looking commentary-  The level of future product sales will depend on several factors, including, but not limited to, the
timing and extent of future regulatory approvals of our products and product candidates, receiving reimbursement pricing,
availability of finished product inventory, approval and commercialization of competitive products and the degree of acceptance of
our products in the marketplace.

We continue to make progress in the FDA review process for FluMist. On August 26, 2002, we completed a rolling submission of our
response to the FDA's Complete Response Letter ("CRL"). We expect to have the opportunity to appear before the Vaccine and Related
Biological Products Advisory Committee ("VRBPAC") in the near future, and have been given a tentative date of December 17, 2002 for
that meeting. The agenda and topics for discussion at that meeting have not yet been finalized, but could include: the relative
risks for asthma and wheezing episodes in children less than five years of age; the potential for vaccine transmission; and the
adequacy of the data set at the ends of the age spectrum (for example, infants under age 2 and adults over age 50). We do not expect
children less than five years of age to be included in the initial indication, if and when approved. We are hopeful that a
successful meeting will result in approval for FluMist during the second quarter of 2003, if not sooner.

Other Revenues - Other revenues increased 80% to $13.4 million in the third quarter of 2002 compared to $7.4 million in the 2001
period, largely the result of $9.0 million from the sale of excess production capacity to a third party and $2.1 million in
funding for FluMist clinical development and sales and marketing activities from Wyeth.  Partially offsetting these increases is a
decrease of $3.8 million in revenue recorded under collaborative agreements.

Forward-looking commentary-  The expected timing of annual revenues to be recognized through 2005 under major collaborative
agreements entered into before January 1, 2002 for which we have accounted for using the contingency adjusted performance model
and deferred a portion of the up-front and milestone payments received, based on current estimates of costs to complete, is as
follows (in millions):

                                                          2002          2003         2004        2005

Future changes in estimated total costs or differences between actual costs and projected costs in any one period could cause the
actual recorded amounts to differ from the projected amounts.  As discussed in "Critical Accounting Policies and Estimates -
Contract Revenues" above, we have adopted the milestone payment method for new contracts entered into or acquired after January 1,
2002.  Because we have adopted this method prospectively, the table above assumes the revenues deferred for these contracts
entered into prior to January 1, 2002 will be recognized in accordance with the contingency-adjusted performance model.

Under the recently amended collaborative agreements with Wyeth, acquired with the Acquisition and associated with FluMist, the
Company expects to receive a $25 million payment in the fourth quarter of 2002 as compensation for manufacturing costs incurred in
preparing for the potential, but now not expected, 2002 FluMist launch.

The level of contract revenues in future periods will depend primarily upon the extent to which we enter into other collaborative
contractual arrangements, if any, and the extent to which we achieve certain milestones provided for in existing agreements.
Future revenues from the sale of excess production capacity will vary depending upon the extent to which we enter into these types
of arrangements, and are not expected to be significant for 2003 or thereafter.

Cost of Sales - Cost of sales for the third quarter of 2002 increased 37% to $22.3 million from $16.3 million in 2001, principally
due to increases in sales volumes.  Overall gross margins for the September 2002 quarter increased to 62% from 59% in the last
year's quarter.   This increase is largely due to the write-off of certain inventories produced at our manufacturing facility in
Nijmegen in the 2001 quarter, partially offset by additional royalty payments in 2002 related to domestic Synagis and Ethyol
sales.

Forward-looking commentary-  We expect that gross margins will vary significantly from quarter to quarter, based on the seasonal
product mix.  We expect that on an annual basis, our gross margin percentage for 2002 will be lower than 2001, largely the result
of the additional royalties owed for Synagis and Ethyol.

Research and Development Expenses - Research, development and clinical expenses increased 50% to $31.8 million in the 2002 third
quarter, compared to $21.2 million in the 2001 quarter, driven by a $10.0 million up-front payment for the license to an early
development-stage technology for the human metapneumovirus (hMPV).  The clinical symptoms of hMPV are largely similar to RSV, both
of which cause serious respiratory infections in young children.  Additionally, the impact of the Acquisition was offset by
reduced spending in other areas of research and development.

In the third quarter of 2002, we completed several important clinical trials, including a successful Phase 3 trial for Synagis in
children with congenital heart disease.  We completed the preliminary analysis of three Phase 2 trials for Siplizumab involving
almost 700 psoriasis patients.  While the drug appeared to be generally well tolerated and patients exhibited an improvement in
their psoriatic disease, an anti-antibody response (also known as immunogenicity) was observed in the laboratory tests of
approximately 50 percent of the patients in the first of these Phase 2 trials (analysis of the other two trials is not yet
completed).  This anti-antibody response did not appear to cause any clinical complications.  However, in 2003 we plan to conduct
retreatment Phase 2 studies to further assess the potential clinical impact of the immunogenicity.

We have also recently completed two Phase 2 trials of our E. coli urinary tract infection vaccine, and have determined that there
is not a sufficient level of efficacy in prevention of urinary tract infections to proceed with additional trials.  Our ongoing
clinical program also includes several product candidates in various phases of evaluation, including a Phase 1 trial in adults
using a liquid formulation of Synagis; several Phase 1 and Phase 2 trials with our human papillomavirus (HPV) cervical cancer
vaccine; Phase 1 trials with Vitaxin in cancer and rheumatoid arthritis; and certain trials for FluMist.  Additionally, we have
multiple programs in the preclinical stage.

Forward-looking commentary - Overall, we expect 2002 clinical spending to increase over 2001 levels as more of our product
candidates move into the clinic and we expand trials on products already in the clinic. In conjunction with the in-licensing
agreement for hMPV technology, the Company is obligated to pay up to $74.4 million in research funding and various milestone
payments subject to the achievement of specified clinical, regulatory and sales milestones. Additionally, during the first half of
2002, we entered into two research collaborations. The Company entered into a research collaboration with Panacea Pharmaceuticals,
Inc. ("Panacea") to develop Human Aspartyl (Asparaginyl) Beta-Hydroxlase ("HAAH") technology. In conjunction with the agreement, the
Company is obligated to pay $3.3 million in research funding over a three-year period and is also obligated to make milestone
payments in the amount of $68.1 million subject to the achievement of specified clinical, regulatory and sales milestones. We also
entered into a research collaboration with A&G Pharmaceuticals, Inc. ("A&G") to license technology relating to PC-Cell
Derived Growth Factor (PCDGF), a monoclonal antibody, the initial indications of which would apply to breast cancer. In conjunction
with the agreement, the Company is obligated to pay up to $5.9 million in various milestone payments subject to the achievement of
specified clinical, regulatory and sales milestones.

Our development-stage efforts and other research and development projects may never reach clinical trials, achieve success in the
clinic, be submitted to the appropriate regulatory authorities for approval, or be approved for marketing or manufacturing by the
appropriate regulatory authorities. Further, we rely on numerous third parties to assist us in various stages of the development
process. Should they be unable to meet our needs, we may incur substantial additional costs. Any of such uncertainties, if they
should occur, could have a material adverse effect on our financial condition and results of operations.

Selling, General, and Administrative Expense - Selling, general and administrative ("SG&A") expense increased 16% to $51.2
million in the third quarter of 2002 compared to $44.2 million in the third quarter of 2001. The increase is primarily attributable
to the Acquisition, including $2.7 million for amortization of intangibles and stock compensation expense for unvested stock options
assumed. Additionally, we experienced increased costs for sales commissions due to increased product sales and increased
co-promotion expense directly related to the sales growth of Synagis in the United States. We also experienced increases in legal
costs, as we are currently involved in several disputes and legal matters. During the 2002 third quarter, we incurred a $5.0 million
charge associated with settling a contractual dispute, regarding an agreement with MBL to transfer certain technology relating to
the Company's monoclonal antibody manufacturing operations. The comparison to last year is also affected by a charge of $13.4
million in 2001 for termination payments associated with the return of marketing rights for Ethyol.

Other Operating Expenses - Other operating expenses were $24.1 million in the 2002 quarter compared to $2.1 million in the 2001
quarter.  The increase is primarily related to pre-production costs and inventory reserves for FluMist, which has not yet been
approved by the FDA.  In addition, we incurred $3.4 million in expense in the 2002 quarter relating to stock compensation for
unvested stock options assumed and amortization of intangibles relating to the Acquisition.  Also included in other operating
expense for both periods are excess capacity costs associated with the plasma production section of our Frederick, Maryland
manufacturing facility.

Forward-looking commentary- While we continue to make progress in the FDA review process for FluMist, we believe that it is unlikely
that FluMist would be approved in time for significant sales for the 2002/2003 flu season. As such, it currently appears probable
that a substantial portion, if not all, of the inventory materials produced in the fourth quarter of 2002 will reach their
expiration dates prior to being utilized. We expect that other operating expenses associated with FluMist will be slightly lower in
the fourth quarter of 2002.

From time to time, we consider cost-saving alternatives, including outsourcing or contract manufacturing. Certain of these
alternatives might result in the write-off of specialized equipment and facilities infrastructure that would not be transferable to
other activities. While we cannot predict with certainty the outcome of these considerations, we believe that such a write-off might
be material to the results of operations for a particular period but would not have a material adverse effect on our financial
position or future operations.

Interest Income and Expense - We earned interest income of $13.3 million during the 2002 quarter, up 45% over the 2001 quarter,
reflecting higher cash balances available for investment, largely due to the Acquisition, partially offset by a decline in
interest rates which lowered our portfolio yield.  Interest expense for the third quarter of 2002, net of amounts capitalized,
increased $2.2 million over third quarter 2001, due to interest expense on the convertible debt assumed in the Acquisition.

Loss on Investment Activities - We incurred $10.6 million in losses on investment activities for the 2002 third quarter.  The
losses consist primarily of impairment write-downs due to the decline in the fair value of certain of our publicly traded equity
investments and other investments in private companies below their cost basis that were judged to be other than temporary.

Taxes - We recorded an income tax benefit of $20.1 million for the quarter ended September 30, 2002, resulting in an effective
rate of 35.7%.  This compares to a tax benefit of $8.4 million recorded for the quarter ended September 30, 2001, based on an
effective tax rate of 30.8%.   The variation in the effective tax rate for 2002 versus 2001 results primarily from differences in
the amount of credits taken for research and development programs and the impact of lower state income tax rates.  These credits
will vary from year to year depending on the activities of the Company.  We believe that our effective tax rate for the full year
of 2002 will be approximately 35.2%.

Net Loss - Net loss for the third quarter of 2002 was $36.3 million, or $0.14 per share, compared to a net loss for the 2001
quarter of $19.0 million, or $0.09 per share.  Shares used in computing net loss per share for the quarter ended September 30,
2002 and September 30, 2001 were 250.8 million and 213.9 million, respectively.  The increase in share count primarily reflects
the additional shares issued in conjunction with the Acquisition.

Forward-looking commentary -  Our quarterly financial results vary significantly due to seasonality of Synagis product sales,
adequate product supply to meet demand, fluctuations in sales of other products, milestone payments, research funding and
expenditures for research, development, clinical and marketing programs.

NINE MONTHS ENDED SEPTEMBER 30, 2002 AND 2001

Product Sales -


          Product Sales (In Millions)             2002            2001
                                                 -----           -----

          Synagis                               $355.7          $266.5

          Ethyol                                 $55.0            $6.0

          Other Products                         $26.5           $31.0
                                                 -----           -----
          TOTAL                                 $437.2          $303.5



Product sales grew 44% to $437.2 million in the nine months ended September 30, 2002 from $303.5 million in the comparable 2001
period, primarily driven by higher sales of Synagis, which accounted for 81% of our product sales for the nine-month period.

Synagis-  Synagis sales increased 34% from $266.5 million in the nine months ended September 30, 2001 to $355.7 million in the
nine months ended September 30, 2002, reflecting 38% growth in domestic unit sales due to increased demand for the product.  Our
reported international sales of Synagis decreased 37% primarily due to a decrease in units sold to Abbott International
("Abbott"), our exclusive distributor of Synagis outside of the United States, and totaled $15.8 million in the 2002 nine months
compared to $25.1 million in the 2001 nine months.  We believe that the decrease is due to reductions in the inventory stocking
levels of Abbott, rather than reduced product demand by end users.  Based upon information received from Abbott, we believe that
end user sales have increased 27% over the comparable prior year period.  The decrease in unit volume was offset by an increase in
the per unit sales price recognized upon delivery of product to Abbott under the terms of our international distribution agreement.

Ethyol- Ethyol sales accounted for approximately 13% and 2% of year-to-date product sales in 2002 and 2001, respectively. Sales of
Ethyol increased from $6.0 million for the nine months ended September 30, 2001 to $55.0 million for the nine months ended September
30, 2002, principally due to our assumption of domestic marketing rights of the product on October 1, 2001 when we began recording
all revenues from domestic sales to wholesalers and distributors. Once reacquired in October 2001, domestic sales volume increased
and we increased the sales price. Domestic Ethyol sales were $51.1 million in the nine-month period in 2002, as compared to $1.6
million in the 2001 period. The amounts for 2001 are net of reductions in Ethyol sales for the buy back of Ethyol inventory from
ALZA in accordance with the reacquisition of marketing rights. As of April 1, 2002, we began paying ALZA a declining royalty based
on net sales of Ethyol in the United States which will continue through 2011. Year-to-date international sales of $3.9 million were
down slightly from the prior year sales of $4.4 million for the comparable period.

Other Products- Sales of other products, which include sales of CytoGam, NeuTrexin, RespiGam, and by-products that result from the
CytoGam manufacturing process, decreased  $4.5 million or 15% for the nine months ended September 30, 2002 from the 2001
comparable period.  CytoGam sales for the nine months ended September 30, 2002 decreased $1.6 million or 7% from the 2001 period.
Unit sales decreased approximately 13%, which was offset by a 10% domestic price increase, which took effect in the first quarter
of 2002.  The Company also experienced decreases in sales of NeuTrexin and by-products.

Other revenues - Other revenues in the nine months ended September 30, 2002 of $28.8 million increased $6.3 million or 28% from
the comparable 2001 period, principally due to $9.0 million from the sale of excess production capacity to a third party and $6.3
million in funding for FluMist clinical development and sales and marketing activities from Wyeth.  Offsetting these increases are
decreases in revenues recognized in accordance with SAB 101 and a $3.6 million decrease in revenues related to sale proceeds
received in 2001 for our Hexalen business.

Cost of sales - Cost of sales for the 2002 nine months increased 54% to $117.8 million from $76.3 million in the 2001 nine months,
principally due to higher sales volume.  Gross margins for the nine month period ended September 30, 2002 were 73% compared to 75%
for the nine month period ended September 30, 2001.  This decrease is principally due to additional royalties payable relating to
Synagis, starting in December 2001.

Research and Development Expenses - Research and development expenses of $110.4 million in the 2002 nine months increased 79% from
$61.6 million in the 2001 nine months, primarily due to higher expenditures on the Company's clinical trials and the impact of the
Acquisition including $5.7 million in expense relating to retention payments, stock option acceleration and stock compensation for
unvested stock options assumed.   As discussed in the analysis of results for the three months ended September 30, 2002 above, we
are conducting trials for several product candidates in various phases of clinical development and have multiple programs in the
preclinical stage.

Selling, General and Administrative Expense- Selling, general and administrative expenses increased 52% to $194.2 million in 2002
compared to $128.2 million for the 2001 period. As a percentage of product sales, SG&A expense increased to 44% of product sales
in the 2002 period from 42% in the 2001 period. The increase in this ratio is largely reflective of the impact of the Acquisition,
including $8.6 million in expense in the 2002 nine-month period relating to retention payments, stock option acceleration and stock
compensation for unvested stock options assumed, and amortization of intangibles. Additionally, we incurred increased costs for
salary and related expenses for the expansion of our Ethyol sales force by adding approximately 40 additional sales representatives
during the second half of 2001 and increased marketing expenses for the relaunch of Ethyol. Higher sales commissions in conjunction
with the increase in product sales and the expansion of Synagis marketing programs contributed to the increase, as well as increased
co-promotion expense directly related to the growth in domestic sales of Synagis. Higher legal expenses for the period included a
$5.0 million charge associated with the settlement of a contractual dispute in August 2002 regarding an agreement with MBL to
transfer certain technology relating to the Company's monoclonal antibody manufacturing operations (see further discussion in the
Legal Proceedings section of this report).

Other Operating Expense- Other operating expenses increased to $68.1 million in the nine months ended September 30, 2002 from $7.7
million in the 2001 period. The increase is principally attributable to pre-production costs and inventory reserves for FluMist,
which has not yet been approved by the FDA.  In addition, we incurred $14.4 million in expense in the 2002 nine-month period
relating to retention payments, stock option acceleration and stock compensation for unvested stock options assumed and
amortization of intangibles relating to the Acquisition.  Also included in other operating expense for both periods are excess
capacity costs associated with the plasma production section of our Frederick manufacturing facility.

In-Process Research and Development - We incurred charges of $1,179.3 million during the nine month period ended September 30,
2002 for the write-off of purchased in-process research and development in conjunction with the Acquisition.  The write-off
represents the fair value of purchased in-process technologies at the acquisition date, calculated utilizing the sum of the
probability-adjusted scenarios under the income approach using a discount rate of 18.7%, and certain in-process research and
development projects, primarily FluMist.  The Company does not anticipate that there will be any alternative future use for the
in-process technologies that were written off.

FluMist is a live, attenuated vaccine delivered via a nasal mist for the prevention of influenza.  We are currently seeking
regulatory approval for the frozen formulation, which requires freezer storage.  The liquid formulation of FluMist, which is
better suited to international markets than the frozen formulation, is currently in Phase 3 clinical trials with our partner,
Wyeth.  While there are other flu vaccines currently marketed by other companies, FluMist would be the only live virus vaccine
administered as a nasal mist.  In October 2000, Aviron had submitted a BLA for FluMist (frozen) to the FDA seeking approval for
licensure.  Aviron received a Complete Response Letter from the FDA on August 31, 2001, and filed its response to this letter on
January 8, 2002.  A second Complete Response Letter was received from the FDA on July 10, 2002 requesting clarification and
additional information relating to clinical data and chemistry, manufacturing and controls data previously submitted.  We
completed our submission of information requested on August 26, 2002.  We are hopeful that a successful meeting with the FDA's
VRBPAC committee in December will result in approval for FluMist during the second quarter of 2003, if not sooner.

The valuation of the acquired in-process research and development is based upon certain estimates and assumptions by management.
The valuation is based upon management's estimates of the probability of FDA approval and commercial success for FluMist.  As with
all biotechnology products, the probability of FDA approval and commercial success for any particular research and development
project is highly uncertain.  Management's projections were based on assumptions, which may or may not remain valid for the
relevant period, including the estimated impact of four "key" factors:  price per dose; dose volume; launch date; and the
potential failure of the frozen or liquid formulations of FluMist.  Based on current information, management believes that the
estimates and assumptions underlying the fair value analysis are substantially accurate. In addition, as of September 30, 2002,
none of the existing manufacturing facilities involved in the production of FluMist had been licensed by any regulatory agency and
FluMist had not yet been manufactured at a sustained commercial scale.  There can be no assurance that these facilities can
achieve licensure by the FDA or any other regulatory agency.  Nor can there be any assurances that if licensed, commercial scale
production could be achieved or sustained.  If we fail to obtain FDA approval for the marketing and manufacture of FluMist, we
will absorb all of the related ongoing expenses while recording no corresponding revenue.

Interest Income and Expense - We earned interest income of $37.2 million for the first nine months of 2002, compared to $28.4
million in the comparable 2001 period, reflecting higher cash balances available for investment, largely due to the Acquisition,
partially offset by a decrease in interest rates which lowered the overall portfolio yield.  Interest expense for the first nine
months of 2002, net of amounts capitalized, increased $6.5 million over the first nine months of 2001 due to interest expense on
convertible debt assumed in the Acquisition.

Loss on Investment Activities - We incurred $10.7 million in losses on investment activities for the nine months ended September
30, 2002.  The losses consist primarily of impairment writedowns due to the decline in the fair value of publicly traded equity
investments and other investments in private companies below their cost basis that were judged to be other than temporary.

Taxes- We recorded an income tax benefit of $1.7 million for the nine months ended September 30, 2002.  Excluding items not
deductible for tax purposes, principally the write-off of purchased in-process research and development, income tax expense
resulted in an effective tax rate of 35.2%.  This compares to tax expense for the nine months ended September 30, 2001 of $29.8
million, resulting in an effective rate of 37.1%.  The variation from the statutory rate in both periods is principally due to the
amount of credits taken for research and development expenditures.

Net Loss -  Net loss for the nine months ended September 30, 2002, which includes the impact of the write off for in-process
research and development, was $1,182.6 million or $4.75 per share.  Shares used in computing net loss per share were 249.1
million.  This compared to net earnings for the comparable period of 2001 of $50.5 million or $0.24 basic and $0.23 diluted
earnings per share.   Shares used in computing basic and diluted earnings per share were 213.1 million and 219.9 million,
respectively.  The increase in share count primarily reflects the additional shares issued in conjunction with the Acquisition.

LIQUIDITY AND CAPITAL RESOURCES

Sources and uses of cash-  The Company's capital requirements have generally been funded from operations, cash and investments on
hand, and issuance of common stock.  Cash and marketable securities (short and long-term) increased 59% to $1.2 billion at
September 30, 2002 from $777.7 million at December 31, 2001.  This increase is due to the impact of the Acquisition, as well as
cash generated from operations.  Working capital increased 7.5% to $451.6 million at September 30, 2002 from $419.9 million at
December 31, 2001 largely due to the Acquisition combined with the seasonal nature of the business.  Also, as a result of the
Acquisition, we have added $200 million in convertible debt with the entire balance due in 2008.

Operating Activities
Net cash provided by operating activities decreased to $43.2 million in the nine months ended September 30, 2002 as compared to
$114.3 million in the comparable 2001 period, primarily as the result of the net loss for the period (excluding the write-off of
in-process research and development and other non-cash items), the seasonal decrease in accrued co-promotion expenses for Synagis,
and the seasonal decrease in royalties payable.  These changes were partially offset by higher allowances for doubtful accounts
receivable.  The Company has made $5.0 million in cash restructuring payments relating to the Acquisition.  The remaining
restructuring liability of $1.4 million is expected to be settled by 2004 with cash generated from operations.

Investing Activities
Cash used for investing activities during the nine months ended September 30, 2002 was $132.5 million, as compared to $191.0 million
in 2001. Cash used for investing activities in 2002 included net additions to our investment portfolio of $227.2 million, offset by
$146.9 in cash acquired as a result of the Acquisition. We also invested $3.7 million in preferred equity securities of two
strategic partners: Panacea, which is developing the HAAH technology; and A&G, which is developing the PC-Cell Derived Growth
Factor (PCDGF) technology. We expended $48.4 million for capital expenditures, primarily for the land purchase for and construction
of our new corporate headquarters in Gaithersburg, Maryland, and for the continued expansion of our manufacturing facilities in
Frederick, Maryland; Philadelphia, Pennsylvania; and Speke, England in the U.K.

Forward-looking commentary -  The Company expects to have approximately $80 million in capital expenditures during 2002.
Construction of the first phase of the new headquarters facility, at a total estimated cost of $85 million, will be funded from
cash generated from operations and investments on hand.  Additionally, the Company has options to purchase an additional 14 acres
of land adjacent to the new facility.  Construction began during March 2002, and the Company expects to take occupancy of the
first phase, a complex of approximately 220,000 square feet, in the fall of 2003.  The majority of the Company's existing space,
which is leased through 2006, is expected to be subleased.  There can be no guarantee that we will be successful in subleasing the
space.

In conjunction with the research and development collaborations with Panacea, A&G and ViroNovative, the Company is obligated to
pay up to $114.4 million in various milestone payments subject to the achievement of specified clinical, regulatory, and sales
milestones and is obligated to make quarterly research and development funding payments.  The Company is also obligated to pay
research and development funding and milestones under various research and development agreements it has entered into.   Payments
due are expected to be funded from cash generated from operations and investments on hand.

Financing Activities
Financing activities generated $36.5 million in cash for the nine months ended September 30, of 2002, as compared to $18.2 million
in 2001.  Approximately $40.9 million was received upon the issuance of common stock relating primarily to the exercise of
employee stock options in 2002, as compared to $18.7 million received in 2001, largely reflecting the inclusion of option
exercises of employees of MedImmune Vaccines subsequent to the Acquisition.  In 2002, repayments on long-term obligations were
$4.4 million, compared to $0.6 million in 2001.


ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Following the Acquisition, the Company's wholly-owned subsidiary MedImmune Vaccines, Inc. is obligated for $200.0 million
aggregate principal amount of 5 1/4% Convertible Subordinated Notes (the "Notes") due 2008.  The Notes were recorded at their fair
value of $211.4 million, based on quoted market prices as of January 10, 2002, the acquisition date.  Interest is payable
semi-annually in arrears in cash on February 1 and August 1 each year.  Changes in interest rates do not affect interest expense
incurred on the Notes, because they bear interest at fixed rates.  The Notes are convertible into an aggregate of 3.4 million
shares of the Company's common stock, based on a conversion price of $58.14, at any time on or before February 1, 2008.  MedImmune
Vaccines may redeem the Notes beginning in February 2004, at  redemption prices declining from 103% of their principal amount in
2004 to 100% in 2008, plus accrued interest.

We periodically enter into foreign exchange forward contracts that permit us to purchase Euros to fund a portion of our inventory
purchase obligations at a fixed exchange rate.  As of September 30, 2002, we had outstanding forward contracts to purchase 6.2
million Euros, all expiring within one year.  Fair value of the outstanding contracts at September 30, 2002 was $0.6 million.  In
addition, during the third quarter of 2002, we entered into foreign exchange forward contracts to purchase 12.5 million British
Pounds (GBPs) to fund payments due under construction contracts denominated in GBPs.  The contracts were designated as cash flow
hedges.  During the third quarter of 2002, the hedges were determined to be ineffective, and all gains and losses on the contracts
were recorded to the income statement, resulting in a net gain of $0.3 million.  During October 2002, the contracts were
subsequently cancelled, at an immaterial loss to the Company.

As of September 30, 2002 we reduced the cost basis of our investments by $10.6 million due to other-than-temporary impairments. The
adjusted cost basis of approximately $10.9 million is invested with strategic partners in various forms of investments, principally
preferred equity securities and convertible preferred equity securities. We carry the majority of these investments at cost,
adjusted for any other-than-temporary declines in value. We evaluate these investments on a quarterly basis, and adjust the carrying
value for other-than-temporary impairments if necessary. Should these investments continue to experience other-than-temporary
impairments, further write-downs could occur, up to the total amount of our investment. Additionally, the Company maintains several
investments in accordance with the equity method. The equity method of accounting requires us to adjust the carrying value of our
investments for our proportionate share of the gains or losses generated by the investees on a quarterly basis. As of September 30,
2002 we recorded year-to-date net writedowns of our equity method investments of $0.1 million. Our total equity investments are
currently $3.6 million. Further writedowns of our investments could occur, up to our total investment, should the investee continue
to incur net losses in future periods.

In July 2002, the Company formed MedImmune Ventures, Inc., a wholly-owned venture capital subsidiary that will assume the
responsibility of the current portfolio of investments in strategic partners and will invest in early-to-late-stage public or
private biotechnology companies focused on discovering and developing human therapeutics.  The fund will invest primarily in areas
of strategic interest to the Company, including infectious disease, immunology and oncology.  The fund initially plans to invest
up to $100.0 million over the next three years.  These investments will be maintained either on the cost or equity method of
accounting, according to the facts and circumstances of the individual investment.  Under either method, the investments will be
subject to adjustment for other-than-temporary impairments.  In addition, investments accounted for under the equity method will
be adjusted for the Company's proportionate share of the investee's gains or losses on a quarterly basis.

Qualitative Disclosures About Market Risk" of the Company's Annual Report on Form 10-K for the year ended December 31, 2001.


ITEM 4.   CONTROLS AND PROCEDURES

Based on an evaluation of the Company's disclosure controls and procedures as of November 4, 2002, our Chief Executive Officer,
Chief Operating Officer, Chief Financial Officer and Chief Accounting Officer have concluded that the Company's disclosure
controls and procedures are effective in connection with the Company's filing of this quarterly report on Form 10-Q for the period
ended September 30, 2002.

There were no significant changes in the Company's internal controls or in any other factors that could significantly affect those
controls, subsequent to the date of the most recent evaluation of the Company's internal controls by the Company, including any
corrective actions with regard to any significant deficiencies or material weaknesses.


                                                     --------------------


The statements in this quarterly report that are not descriptions of historical facts may be forward-looking statements.  Those
statements involve substantial risks and uncertainties.  You can identify those statements by the fact that they contain words
such as "anticipate," "believe," "estimate," "expect," "intend," "project" or other terms of similar meaning.  Those statements
reflect management's current beliefs, but are based on numerous assumptions which MedImmune cannot control and which may not
develop as MedImmune expects.  Consequently, actual results may differ materially from those projected in the forward - looking
statements.  Among the factors that could cause actual results to differ materially are:  seasonal demand for and continued supply
of the Company's principal product, Synagis; whether FluMist receives clearance by the Food and Drug Administration and, if it
does, whether it will be successfully launched; availability of competitive products in the market; availability of third-party
reimbursement for the cost of our products; effectiveness and safety of our products; exposure to product liability, intellectual
property or other types of litigation; foreign currency exchange rate fluctuations; changes in generally accepted accounting
principles; growth in costs and expenses; the impact of acquisitions, divestitures and other unusual items; and the risks,
uncertainties and other matters discussed in this quarterly report and in our periodic reports filed with the United States
Securities and Exchange Commission.  MedImmune cautions that RSV disease occurs primarily during the winter months; MedImmune
believes its operating results will reflect that seasonality for the foreseeable future.  MedImmune is also developing several
products (including FluMist) for potential future marketing.  There can be no assurance that such development efforts will
succeed, that such products will receive required regulatory clearance or that, even if such regulatory clearance were received,
such products would ultimately achieve commercial success.  Unless otherwise indicated, the information in this quarterly report
is as of September 30, 2002.  This quarterly report will not be updated as a result of new information or future events.


                                                                   PART II
                                                              OTHER INFORMATION

Item 1.  Legal Proceedings
In 1998, MediGene AG ("MediGene") initiated a legal action against Loyola University of Chicago ("Loyola") and the Company in the
United States District Court for the Northern District of Illinois alleging, among other things, breach of contract and tortious
interference by the Company with an alleged prospective business relationship between MediGene and Loyola. The claims relate to
human papillomavirus vaccine technology allegedly covered by contracts between MediGene and the Company and by a license agreement
from Loyola to the Company, under which the Company granted a sublicense to GlaxoSmithKline.  MediGene seeks damages from the
Company ranging from $31.3 million to $86.9 million based on the tortious interference claim, and/or damages ranging from $10.2
million to $31.3 million based on the breach of contract claim.  MediGene also seeks ownership of the patents in question, as well
as rescission of the Company's license agreement from Loyola or rights as a third-party beneficiary thereof.  The District Court
has granted summary judgment in favor of the Company on all claims and MediGene has appealed.

In October 2000, Celltech Chiroscience Limited ("Celltech") commenced a legal proceeding against the Company in the U.K. High
Court of Justice, Chancery Division, Patents Court.  Celltech alleges that the Company failed to pay royalties with respect to its
sales of Synagis as required by a license agreement dated January 19, 1998.  Under the agreement, the Company obtained from
Celltech a worldwide license to make, use and/or sell product under a patent (and related applications) pertaining to humanized
antibodies.  In the proceeding, Celltech seeks payment of a 2% royalty based on net sales of Synagis sold or manufactured in the
United States, with interest, and certain costs, including attorney's fees.  The Company filed answering papers denying that any
royalties are due on the basis that Celltech's United States patent does not cover Synagis and has sought dismissal of the case on
the grounds that the legal doctrine of prosecution history estoppel prevents Celltech from claiming that its patent covers
Synagis. On October 28, 2002, the High Court of Justice ruled in favor of the Company and dismissed Celltech's case on this basis
after a hearing was held before the Court on early October 2002.  Celltech is expected to appeal.

On November 29, 2001, the Company received a letter from counsel for Celltech enclosing a copy of a patent granted by the European
Patent Office on November 14, 2001.  That letter requested various information concerning the manufacture and sale of Synagis in
Europe and sought confirmation that the Company would pay royalties on such sales pursuant to the license agreement dated January
19, 1998.  On September 16, 2002, Celltech (now known as Celltech R&D Limited) commenced a second legal proceeding against the
Company in the U.K. High Court of Justice, Chancery Division, Patents Court, based on the license agreement dated January 19,
1998.  Celltech seeks payment of a 2% royalty based on net sales of Synagis sold or manufactured in Germany, with interest and
certain costs, including attorney fees.  As of November 7, 2002, the Company had not made the royalty payments that were the
subject of Celltech's November 29, 2001 letter or its September 16, 2002 lawsuit.  The Company's answering papers are due on
December 4, 2002.

On December 18, 2001, Genentech, Inc. ("Genentech") announced that it had been granted a patent relating to certain methods and
compositions used to produce antibodies by recombinant DNA technology.  In June 1997, in anticipation of any potential impact the
issuance of Genentech's patent could have on the production of Synagis, the Company obtained a license to this patent.  The
Company has received from Genentech a letter, dated January 7, 2002, stating that Genentech expects to receive from the Company
royalty payments pursuant to such license. The Company is in the process of evaluating whether any valid claim of Genentech's
patent, as recently issued, covers production of Synagis.  Pending resolution of this issue, the Company has made certain royalty
payments to Genentech under protest and with reservation of all of its rights.  The Company is also evaluating whether any of its
other antibody-based product candidates, if and when approved for marketing by the United States Food and Drug Administration,
could require a license under the Genentech patent.  For additional information on risk associated with patent licenses, please
refer to Part 1, Item 1, Business - Risk Factors of the Company's Annual Report on Form 10-K for the year ended December 31, 2001.

On February 28, 1996, Ichthyol Gesellschaft Cordes, Hermanni & Co. ("Ichthyol Gesellschaft") filed a complaint for refrain,
information and damages with the Regional Court of Hamburg against MedImmune Oncology on the grounds of trademark infringement in
respect of the use of the trademark "Ethyol" in Germany.  No monetary amount is currently being sought in the litigation by
Ichthyol.  Ichthyol is seeking injunctive relief against the use of the trademark Ethyol in Germany.  The suit was dismissed on
January 29, 1997 by the Regional Court of Hamburg.  Ichthyol Gesellschaft filed an appeal and a  judgment was rendered in favor of
MedImmune Oncology in the appellate proceedings.  In January 1999, Ichthyol Gesellschaft filed an appeal on points of law with the
Federal Court of Justice, and in June 1999, Ichthyol Gesellschaft filed the grounds for the appeal on points of law.  By judgment
of May 3, 2001, the Federal Court of Justice reversed the judgment of the Higher Regional Court and remitted the case to that
court for another hearing.  By order of December l9, 2001, the Higher Regional Court ordered Ichthyol to make further submissions
concerning the relevant facts and legal questions.  Ichthyol recently filed its submissions.  Another hearing will probably be
held this fall.

The Company has been involved in a contract dispute with the University of Massachusetts Biologic Laboratories ("MBL") regarding
the Company's agreement to transfer to MBL certain technology relating to the Company's monoclonal antibody manufacturing
operations.  During the third quarter of 2002, the parties agreed to a settlement of the dispute for a $5 million payment by the
Company, which was charged to the income statement.  The Company also secured the return of the rights to "make, have made, use
and sell" the Company's monoclonal antibody for RSV in the Commonwealth of Massachusetts and State of Maine in exchange for a
royalty.

On April 5, 2002, the Company filed a suit against Centocor, Inc. ("Centocor") in the United States District Court for the
District of Maryland.  The Company currently pays Centocor a royalty for sales of Synagis made or sold in the United States
pursuant to a patent Sublicense Agreement between the parties dated as of September 15, 2000 (the "Sublicense Agreement").  In the
litigation, the Company seeks a declaratory judgment that it has no obligation to continue paying royalties to Centocor on the
basis that the patent is invalid, unenforceable and does not cover Synagis.  Additionally, the Company seeks an injunction
preventing Centocor from enforcing this patent.  On July 1, 2002, Centocor moved to dismiss this action on the basis that it did
not include the Trustees of Columbia University in the City of New York ("Columbia") and the Board of Trustees of the Leland
Stanford University ("Stanford"), as the owners of the patent.  On July 9, 2002, Centocor, Columbia and Stanford initiated an
action against the Company in the United States District Court for the Northern District of California.  In the California
litigation, Centocor, Columbia and Stanford sought a declaratory judgment that the patent at issue in the Sublicense Agreement is
valid and enforceable and that the Company would be liable for patent infringement but for the Sublicense Agreement, as well as a
declaratory judgment that the Sublicense Agreement is enforceable.  The Company moved to dismiss the California action, among
other arguments, on the basis that a prior action was filed in the U.S. District Court for the State of Maryland and the
California action should not go forward.  On October 21, 2002, the court ruled in favor of the Company and dismissed the
California litigation.  There can be no assurance that the Company will be successful in this dispute.
                                                    ----------------------------

After consultation with its counsel, the Company believes that it has meritorious defenses to the claims against it referred to
above and is determined to defend its position vigorously.  While it is impossible to predict with certainty the eventual outcome
of these proceedings, the Company believes they are unlikely to have a material adverse effect on its financial position but might
have a material adverse effect on its results of operations for a particular period.






Item 2.           Changes in Securities - None

Item 3.           Defaults upon Senior Securities - None

Item 5.           Other Information -

Update to Risk Factors:

Our products may receive further scrutiny after approval by regulatory agenies for adverse events relating to the product.

Prior to approval by the FDA, as well as international regulatory agencies, drug products are subject to rigorous preclinical and
clinical testing for safety and efficacy. From these trials, a product's "adverse event profile" is identified. This profile is
disclosed on each product's Package Insert, which is a printed page accompanying the product, to inform physicians and patients as
to what side effects they might encounter with a given product's use. Following approval, MedImmune monitors all of its drug
products to maintain a current safety database, tracking identified adverse events from a drug's use in broader populations. Such
adverse events are reported to the appropriate regulatory authorities. Periodically, discussions with regulatory agencies may occur
regarding adverse event reports. Such discussions may result in changes to the disclosures in the Package Inserts for the Company's
products and communications with health care professionals to apprise them of such changes. During 2002, modifications were made to
the Package Inserts for Neutrexin, Ethyol, and Synagis reflecting information gained from product use.

I, David M. Mott, certify that:

1.       I have reviewed this quarterly report on Form 10-Q of MedImmune, Inc. (the "Company");

2.       Based on my knowledge, this quarterly report does not contain any untrue statement of a material fact or omit to state a
         material fact necessary to make the statements made, in light of the circumstances under which such statements were made,
         not misleading with respect to the period covered by this quarterly report;

         procedures (as defined in Exchange Act Rules 13a-14 and 15d-14) for the registrant and we have:

                  a.  designed such disclosure controls and procedures to ensure that material information relating to the
                      Company, including its consolidated subsidiaries, is made known to us by others within those entities,
                      particularly during the period in which this quarterly report is being prepared;
                  b.  evaluated the effectiveness of the Company's disclosure controls and procedures as of November 4, 2002 (the
