The Offering:

         This Prospectus  relates to the sale of up to 21,300,000  shares of our
common  stock by Fusion  Capital  Fund II,  LLC.  Fusion  Capital  is  sometimes
referred to in this Prospectus as the selling  stockholder.  The prices at which
Fusion Capital may sell the shares will be determined by the  prevailing  market
price for the shares or in negotiated transactions. We will not receive proceeds
from the sale of our shares by Fusion Capital, but we will receive proceeds from
sales of shares to Fusion Capital.

         Our common stock is registered  under  Section 12(g) of the  Securities
Exchange Act of 1934 and quoted on the NYSE Amex  (formerly,  the American Stock
Exchange)  under the symbol  "HEB." On April 23, 2009,  the last  reported  sale
price for our common stock as reported on the NYSE Amex was $0.48 per share.

         The  selling  stockholder  may sell its shares from time to time on the
NYSE  Amex or  otherwise,  in one or  more  transactions  at  fixed  prices,  at
prevailing  market  prices  at the  time of sale or at  prices  negotiated  with
purchasers.  The selling  stockholder will be responsible for any commissions or
discounts due to brokers or dealers.  We will pay  substantially all expenses of
registration of the shares covered by this Prospectus.

About Hemispherx

         We are a biopharmaceutical company engaged in the clinical development,
manufacture,  marketing and  distribution of new drug therapies based on natural
immune system enhancing technologies for the treatment of viral and immune based
chronic  disorders.  We were founded in the early 1970s doing contract  research
for the National  Institutes of Health.  Since that time, we have  established a
strong foundation of laboratory, pre-clinical, and clinical data with respect to
the development of nucleic acids to enhance the natural antiviral defense system
of the human body and to aid the  development  of  therapeutic  products for the
treatment of certain chronic diseases.

         Our current  strategic  focus is derived from four  applications of our
two  core  pharmaceutical   technology  platforms   Ampligen(R)  and  Alferon  N
Injection(R).  The  commercial  focus for  Ampligen  includes  application  as a
treatment  for  Chronic  Fatigue  Syndrome  ("CFS")  and as a  vaccine  enhancer
(adjuvant) for both therapeutic and preventative vaccine development.  Alferon N
Injection(R)  is an FDA approved  product with an indication  for  refractory or
recurring genital warts. Alferon LDO (Low Dose Oral) is an application currently
under early stage development  targeting influenza and viral diseases both as an
adjuvant as well as a single entity anti-viral.

           Ampligen(R) is an  experimental  drug currently  undergoing  clinical
development  for the  treatment of CFS. In August 2004, we completed a Phase III
clinical trial ("AMP 516") treating over 230 CFS patients with  Ampligen(R)  and
are presently in the  registration  process for a new drug  application  ("NDA")
with the Food and Drug  Administration  ("FDA").  Ampligen  represents the first
drug in the class of RNA (nucleic acid) molecules to apply for NDA review.

         On July 7, 2008,  the FDA accepted our NDA for review.  On February 18,
2009, we were  notified by the FDA that the  originally  scheduled  Prescription
Drug User Fee Act date of February 25, 2009 has been extended to May 25, 2009.

         We own and  operate a 43,000  sq.  ft.  FDA  approved  facility  in New
Brunswick, NJ primarily designed to produce Alferon N Injection(R).  In 2006, we
completed the installation of a polymer  production line to produce  Ampligen(R)
raw materials on a more reliable and consistent basis.

         Our principal  executive  offices are located at One Penn Center,  1617
JFK Boulevard,  Philadelphia,  Pennsylvania  19103,  and our telephone number is
215-988-0080. We maintain a website at "http://www.hemispherx.net."  Information

Fusion Capital Transaction

         On July 2, 2008, we entered into a Common Stock Purchase Agreement with
Fusion Capital Fund II, LLC, an Illinois limited  liability  company.  Under the
Purchase Agreement,  Fusion Capital is obligated,  under certain conditions,  to
purchase shares from us in an aggregate amount of up to $30 million from time to
time  over a 25 month  period  from  August  21,  2008.  Under  the terms of the
Purchase  Agreement,  Fusion Capital has received a commitment fee consisting of
650,000 shares of our common stock.  Also, we will issue to Fusion Capital up to
an additional  650,000 shares as a commitment fee pro rata as we receive the $30
million of future funding. We originally  registered herein 21,300,000 shares in
the  aggregate,  consisting  of  20,000,000  shares  which we may sell to Fusion
Capital and 1,300,000  shares we have issued or may issue to Fusion Capital as a
commitment  fee. As of April 23,  2009 we have sold an  aggregate  of  4,377,515
shares to Fusion  Capital  (exclusive of any shares issued as a commitment  fee)
under the Purchase Agreement for gross proceeds of approximately $1,860,000.

         Our common  stock is quoted on the NYSE Amex  (formerly,  the  American
Stock  Exchange)  under the symbol "HEB." In connection  with this  transaction,
under the rules of the NYSE Amex, we may not issue more than  14,823,651  shares
(19.99% of our  outstanding  shares as of July 2, 2008, the date of the Purchase
Agreement)  without first obtaining the approval of our stockholders.  Under the
Purchase  Agreement and a Registration  Rights  Agreement with Fusion Capital we
are  required to register  and have  included in the  offering  pursuant to this
Prospectus (1) 650,000 shares which have already been issued,  (2) an additional
650,000  shares which we may issue in the future as a commitment fee pro rata as
we receive up to the $30 million of future  funding and (3) at least  13,523,651
shares which we may sell to Fusion Capital after this registration  statement is
declared  effective.  In the  aggregate,  this is  14,823,651  or  19.99% of our
outstanding shares on July 2, 2008, the date of the Purchase Agreement.

         Under the Purchase Agreement,  we have the right but not the obligation
to sell  more  than the  20,000,000  shares to  Fusion  Capital  (excluding  the
1,300,000  shares we have issued or may issue to Fusion  Capital as a commitment
fee). This 21,300,000 shares is greater than 19.99% of our outstanding shares of
common stock as of the date of the Purchase Agreement.  On November 11, 2008, at
our Annual  Meeting of  Stockholders,  we received  stockholder  approval of the
Purchase  Agreement  in order to be in  compliance  with  the  NYSE  Amex  rules
permitting us to sell more than 14,823,651 or 19.99% of our  outstanding  shares
on July 2, 2008, the date of the Purchase Agreement.

         As of the date of this  Prospectus,  we do not have any plans or intent
to sell to Fusion Capital any shares beyond the 20,000,000 shares offered hereby
(excluding the 1,300,000 shares we have issued or may issue to Fusion Capital as
a commitment fee). However, if we elect to sell more than the 20,000,000 shares,
which we have the right but not the  obligation  to do, we must  first  register
under the Securities  Act any  additional  shares we may elect to sell to Fusion
Capital before we can sell such additional shares, which could cause substantial
dilution to our stockholders.
 6
         Generally,  we have the right but not the obligation  from time to time
to sell our  shares to Fusion  Capital  in  amounts  between  $120,000  and $1.0
million depending on certain conditions. We have the right to control the timing
and amount of any sales of our shares to Fusion  Capital.  The purchase price of
the shares will be determined  based upon the market price of our shares without
any fixed  discount at the time of each sale.  Fusion  Capital does not have the
right nor the  obligation  to  purchase  any shares of our  common  stock on any
business  day that the price of our common  stock is below  $0.40.  There are no
negative  covenants,  restrictions on future  fundings,  penalties or liquidated
damages in the Purchase  Agreement or the  Registration  Rights  Agreement.  The
Purchase Agreement may be terminated by us at any time at our discretion without
any cost to us.

         The number of shares  ultimately  offered for sale by Fusion Capital is
dependent  upon the  number of shares  purchased  by  Fusion  Capital  under the
Purchase Agreement.


                                  RISK FACTORS

         The following  cautionary  statements  identify  important factors that
could cause our actual results to differ  materially from those projected in the
forward-looking  statements made in this Prospectus.  Among the key factors that
have a direct bearing on our results of operations are:

Risks Associated With Our Business

No assurance of successful product development.

         Ampligen(R)  and related  products.  The development of Ampligen(R) and
our  other  related  products  is  subject  to a number  of  significant  risks.
Ampligen(R) may be found to be ineffective or to have adverse side effects, fail
to receive  necessary  regulatory  clearances,  be difficult to manufacture on a
commercial   scale,   be   uneconomical   to   market  or  be   precluded   from
commercialization  by proprietary  right of third  parties.  Our products are in
various stages of clinical and  pre-clinical  development  and,  require further
clinical studies and appropriate  regulatory  approval processes before any such
products can be marketed. We do not know when, if ever, Ampligen(R) or our other
products will be generally  available for  commercial  sale for any  indication.
Generally,  only a  small  percentage  of  potential  therapeutic  products  are
eventually  approved by the FDA for  commercial  sale.  Please see the next risk
factor.

         Alferon N Injection(R). Although Alferon N Injection(R) is approved for
marketing in the United States for the intra-lesional treatment of refractory or
recurring  external  genital warts in patients 18 years of age or older, to date
it has not been  approved  for  other  indications.  We face  many of the  risks
discussed  above,  with regard to developing this product for use to treat other
ailments.



 7



Our drug and related  technologies are investigational and subject to regulatory
approval. If we are unable to obtain regulatory approval, our operations will be
significantly adversely affected.

         All of our drugs and  associated  technologies,  other  than  Alferon N
Injection(R),  are investigational and must receive prior regulatory approval by
appropriate  regulatory  authorities  for general use and are currently  legally
available only through  clinical  trials with specified  disorders.  At present,
Alferon N  Injection(R)  is only  approved for the  intra-lesional  treatment of
refractory  or recurring  external  genital warts in patients 18 years of age or
older.  Use of  Alferon  N  Injection(R)  for  other  indications  will  require
regulatory approval.

         Our  products,   including   Ampligen(R),   are  subject  to  extensive
regulation by numerous governmental authorities in the U.S. and other countries,
including, but not limited to, the FDA in the U.S., the Health Protection Branch
("HPB") of  Canada,  and the Agency for the  Evaluation  of  Medicinal  Products
("EMEA") in Europe.  Obtaining  regulatory  approvals  is a rigorous and lengthy
process and requires  the  expenditure  of  substantial  resources.  In order to
obtain  final  regulatory  approval of a new drug,  we must  demonstrate  to the
satisfaction of the regulatory agency that the product is safe and effective for
its intended  uses and that we are capable of  manufacturing  the product to the
applicable  regulatory  standards.  We require  regulatory  approval in order to
market Ampligen(R) or any other proposed product and receive product revenues or
royalties. We cannot assure you that Ampligen(R) will ultimately be demonstrated
to be safe or efficacious.  In addition, while Ampligen(R) is authorized for use
in clinical  trials  including a cost recovery  program in the United States and
Europe,  we cannot assure you that  additional  clinical trial approvals will be
authorized in the United States or in other countries, in a timely fashion or at
all, or that we will complete these clinical trials.

         We filed an NDA with the FDA for  treatment of CFS on October 10, 2007.
On December 5, 2007 we received an RTF letter from the FDA as our NDA filing was
deemed "not  substantially  complete".  We  responded  to the FDA's  concerns by
filing  amendments to our NDA on April 25, 2008. These  amendments  should allow
the  FDA   reviewers   to  better   evaluate   independently   the   statistical
efficacy/safety  conclusions  of our NDA for the use of  Ampligen(R) in treating
CFS. On July 7, 2008 the FDA accepted our NDA filing for review.  However, there
are no  assurances  that upon  review of the NDA that it will be approved by the
FDA. On  February  18,  2009,  we were  notified by the FDA that the  originally
scheduled  Prescription  Drug User Fee Act date of  February  25,  2009 has been
extended to May 25, 2009.
 8
         If Ampligen(R) or one of our other products does not receive regulatory
approval in the U.S. or elsewhere, our operations most likely will be materially
adversely affected.

We may  continue to incur  substantial  losses and our future  profitability  is
uncertain.

         We began  operations  in 1966 and last  reported  net profit  from 1985
through 1987. Since 1987, we have incurred  substantial  operating losses, as we
pursued our clinical  trial effort to get our  experimental  drug,  Ampligen(R),
approved.  As of December 31, 2008, our  accumulated  deficit was  approximately
$197,409,000.  We have not yet generated  significant revenues from our products
and may incur  substantial and increased losses in the future.  We cannot assure
that we will ever achieve  significant  revenues  from  product  sales or become
profitable.  We  require,  and will  continue  to  require,  the  commitment  of
substantial resources to develop our products. We cannot assure that our product
development  efforts will be successfully  completed or that required regulatory
approvals  will be  obtained  or that  any  products  will be  manufactured  and
marketed successfully, or be profitable.

We may require additional financing which may not be available.

         The  development  of  our  products  will  require  the  commitment  of
substantial  resources  to  conduct  the  time-consuming  research,  preclinical
development,  and clinical  trials that are  necessary  to bring  pharmaceutical
products to market. As of December 31, 2008, we had approximately  $6,119,000 in
cash and cash equivalents and short-term  investments.  Given the harsh economic
conditions,  we have  reviewed  every  aspect  of our  operations  for  cost and
spending  reductions  to assure  the long term  survival  of our  Company  while
maintaining  the  resources  necessary  to achieve  our  primary  objectives  of
obtaining NDA approval of Ampligen(R) and securing a strategic partner. Based on
these  actions,  we  anticipate,  but cannot  assure,  that these  funds will be
sufficient to meet our operating cash requirements for the next 16 months.

         We have in place two  potential  sources  of  financing:  1) the Common
Stock Purchase Agreement (the "Purchase Agreement") with Fusion Capital Fund II,
LLC ("Fusion")  pursuant to which we have the right to sell shares of our Common
Stock to  Fusion;  and 2) a Standby  Financing  Agreement  with  certain  of our
executives, directors and strategic consultants.

         We  anticipate,  but  cannot  assure,  that we  will  be able to  raise
additional  capital from the sale of shares to Fusion Capital under the Purchase
Agreement. Pursuant to the Purchase Agreement, we only have the right to receive
$120,000 every two business days unless our stock price equals or exceeds $0.80,
in which case we can sell greater  amounts to Fusion Capital as the price of our
common  stock  increases.  Fusion  Capital  does  not  have  the  right  nor the
obligation  to purchase  any shares of our common stock on any business day that
the market price of our common  stock is less than $0.40.  As of April 23, 2009,
we have sold an aggregate of 4,377,515  shares to Fusion  Capital  (exclusive of
any shares  issued as a commitment  fee) under the Purchase  Agreement for gross
proceeds of  approximately  $1,860,000.  Since we  registered  an  aggregate  of
20,000,000  shares  for  sale to  Fusion  Capital  pursuant  to this  Prospectus
(exclusive of the 1,300,000  shares issued or to be issued as a commitment fee),
the  selling  price of the  remaining  15,622,485  shares  we can sell to Fusion
Capital  will have to  average at least  $1.80 per share for us to  receive  the
maximum  proceeds of $30 million.  Assuming a purchase  price of $0.48 per share
(the  closing sale price of the common stock on April 23, 2009) and the purchase
by Fusion Capital of the full  15,622,485  shares  remaining  under the Purchase
Agreement,  proceeds to us would only be $7,498,793.  Subject to approval by our
board of directors,  we have the right but not the obligation to issue more than
20,000,000  shares to Fusion  Capital.  In the event we elect to issue more than
20,000,000 shares offered hereby, we will be required to file a new registration
statement  and  have  it  declared  effective  by the  Securities  and  Exchange
Commission.
 9
         The extent we rely on Fusion Capital as a source of funding will depend
on a number of factors  including,  the  prevailing  market  price of our common
stock and the extent to which we are able to secure  working  capital from other
sources. Specifically, Fusion Capital does not have the right nor the obligation
to purchase any shares of our common stock on any business  days that the market
price of our common stock is less than $0.40.  While the current market price is
in excess of $0.40  per  share,  during  the past few  months,  the price of our
common stock often has been below $0.40.

         In  February  2009,  we  entered  into a  Standby  Financing  Agreement
pursuant to which certain individuals ("Individuals"),  consisting of Dr. Carter
and Thomas  Equels,  agreed to loan us up to an aggregate of $1,000,000 in funds
should we be unable to obtain additional financing, if needed. Under the Standby
Financing Agreement,  we will use our best efforts in 2009 to obtain one or more
additional  financing  agreements  on  such  terms  as  our  Board  deems  to be
reasonable and appropriate in order to maintain our  operations.  If at any time
after December 1, 2009 and prior to June 30, 2010 a majority of our  independent
Directors  deems that in the event a financing  of at least $2.5 Million has not
been obtained and  additional  funds are needed to maintain our  operations,  we
will send a  written  notice to each of the  Individuals  informing  them of the
total amount of additional  funds required and the specific  amount that will be
required from each Individual. Within fifteen calendar days after receipt of the
notice,  the Individuals will be required to pay us their respective  amount. We
will then issue to them one year 15% senior  secured notes for their  respective
amounts  (the  "Notes").  Interest  will be paid  monthly in our  Common  Stock.
Repayment of the principal  and interest  under the Notes will be secured by all
of our assets.  We will not, without the consent of the  Individuals,  (i) incur
any new debt  senior  or pari  passu to the  Notes or (ii)  encumber  or grant a
security  interest in any assets.  Upon 20 business days written notice,  we may
prepay the Notes in cash at any time at 105% of the then  outstanding  principal
amount of the Notes, plus any accrued but unpaid interest.

         For agreeing to be obligated to loan us money, each Individual received
10 year warrants (the "Commitment Warrants") to purchase our common stock at the
rate of $50,000 worth in warrants per $100,000 committed.  The exercise price of
these warrants is $0.51 (125% of the market closing price of our Common Stock on
the date that Agreement was executed). These warrants vested immediately. If and
when we notify the Individuals that we are  consummating the Standby  Financing,
upon  each  Individual's  payment  of his  committed  amount,  he  will  receive
additional  10 year warrants to purchase our Common Stock at the rate of $50,000
worth in warrants per $100,000  paid. The exercise price of the warrants will be
the  closing  market  price of our Common  Stock on the day we receive the funds
from the Individuals. These warrants will vest immediately. While any portion of
the Notes are outstanding,  Individuals will have weighted average anti-dilution
rights with regard to the exercise price of all warrants  issued pursuant to the
Standby Financing, except that these rights will not apply if the securities are
issued to employees,  Board members,  corporate and scientific advisors,  select
vendors,  pursuant to the Purchase  Agreement  with Fusion  Capital or part of a
corporate or strategic alliance.

If we are unable to obtain  sufficient  financing from the sale of securities to
Fusion  Capital and/or the Standby  Financing  Agreement and if we are unable to
commercialize and sell Ampligen(R), Alferon N Injection(R) or other products, we
will need to secure other sources of funding through  additional  equity or debt
financing or from other  sources in order to satisfy our working  capital  needs
and to  complete  the  necessary  clinical  trials and the  regulatory  approval
processes including the commercializing of Ampligen(R)  products. In this regard
we  previously  registered  $50,000,000  worth of our  securities in a universal
 10
shelf  registration  statement,  none of which has been designated or issued. We
are  unable to  estimate  the  amount,  timing  or  nature  of  future  sales of
outstanding common stock or instruments  convertible into or exercisable for our
common stock.  Should the financing we require be unavailable  or  prohibitively
expensive  when we require  it,  the  consequences  could be a material  adverse
effect on our ability to develop our products or continue our operations.

Our Alferon N Injection(R)  Commercial Sales have halted due to lack of finished
goods inventory.

         Our finished  goods  inventory of Alferon N  Injection(R)  reached it's
expiration  date in March 2008. As a result,  we have no product to sell at this
time.  The FDA has  declined to respond to our  requests for an extension of the
expiration  date,  therefore  we consider  the  request to be denied.  Since our
testing of the product  indicates  that it is not  impaired  and could be safely
utilized, the finished goods inventory of 2,745 Alferon N Injection(R) 5ml vials
may be used to produce approximately 11,000,000 sachets of Low Dose Oral Alferon
(LDO) for future clinical trials.

         Production  of  Alferon  N  Injection(R)   from  our   work-in-progress
inventory,  which has an  approximate  expiration  date of 2012, has been put on
hold at this time due to the  resources  needed  to  prepare  our New  Brunswick
facility for the FDA preapproval inspection with respect to our Ampligen(R) NDA.
Work on the Alferon N  Injection(R)  is expected to resume in mid-2009 under the
condition  that adequate  funding is obtained,  which means that we may not have
any Alferon N Injection(R) product commercially available until 2010.

         In 2007,  we averaged  Alferon N  Injection(R)  sales of  approximately
$77,000 per month. However with no FDA approval to extend the expiration date of
our finished good inventory,  we will no longer receive these monthly  revenues.
In addition,  if there is a  significant  absence of the product from the market
place, no assurance can be given that sales will return to prior levels.

Although  preliminary in vitro testing  indicates that Ampligen(R)  enhances the
effectiveness  of different drug  combinations on avian  influenza,  preliminary
testing in the laboratory is not necessarily predictive of successful results in
clinical testing or human treatment.

         Ampligen(R)  continues  to undergo  pre-clinical  testing for  possible
treatment of avian flu.  Although  preliminary  in vitro testing  indicates that
Ampligen(R)  enhances the  effectiveness of different drug combinations on avian
flu,  preliminary  testing in the  laboratory is not  necessarily  predictive of
successful  results in clinical testing or human treatment.  No assurance can be
given  that  similar  results  will  be  observed  in  clinical  trials.  Use of
Ampligen(R)  in the treatment of avian flu requires prior  regulatory  approval.
Only the FDA can  determine  whether a drug is safe,  effective or promising for
treating  a  specific  application.  As  discussed  in the  prior  risk  factor,
obtaining regulatory approvals is a rigorous and lengthy process.

         In addition,  Ampligen(R) is currently being tested on strains of avian
influenza virus.  There are a number of strains and strains mutate. No assurance
can be given that Ampligen(R) will be effective on any strains that might infect
humans.
 11
We may not be  profitable  unless we can  protect  our  patents  and/or  receive
approval for additional pending patents.

         We need to preserve and acquire enforceable patents covering the use of
Ampligen(R) for a particular disease in order to obtain exclusive rights for the
commercial  sale of  Ampligen(R)  for such  disease.  We obtained  all rights to
Alferon N Injection(R),  and we plan to preserve and acquire enforceable patents
covering its use for existing and potentially new diseases. Our success depends,
in large part, on our ability to preserve and obtain patent  protection  for our
products and to obtain and preserve our trade secrets and expertise.  Certain of
our know-how and technology is not patentable,  particularly  the procedures for
the  manufacture of our  experimental  drug,  Ampligen(R),  which is carried out
according  to standard  operating  procedure  manuals.  We also have been issued
patents on the use of Ampligen(R)  in  combination  with certain other drugs for
the treatment of chronic  Hepatitis B virus,  chronic  Hepatitis C virus,  and a
patent which  affords  protection  on the use of  Ampligen(R)  in patients  with
Chronic Fatigue Syndrome.  We have not yet been issued any patents in the United
States for the use of  Ampligen(R)  as a sole  treatment for any of the cancers,
which we have sought to target.  With regard to Alferon N Injection(R),  we have
acquired from ISI its patents for natural alpha  interferon  produced from human
peripheral  blood  leukocytes  and its  production  process  and we have filed a
patent  application  for the use of Alferon(R)  LDO in treating  viral  diseases
including avian  influenza.  We cannot assure that our competitors will not seek
and obtain patents  regarding the use of similar  products in  combination  with
various  other agents,  for a particular  target  indication  prior to our doing
such.  If we cannot  protect our patents  covering the use of our products for a
particular  disease,  or  obtain  additional  patents,  we may  not be  able  to
successfully market our products.

The  patent  position  of  biotechnology  and  pharmaceutical  firms  is  highly
uncertain and involves complex legal and factual questions.

         To date,  no  consistent  policy has emerged  regarding  the breadth of
protection afforded by pharmaceutical and biotechnology patents. There can be no
assurance  that new patent  applications  relating to our products or technology
will result in patents being issued or that, if issued, such patents will afford
meaningful  protection  against  competitors  with  similar  technology.  It  is
generally  anticipated that there may be significant  litigation in the industry
regarding patent and intellectual property rights. Such litigation could require
substantial  resources  from  us and we may not  have  the  financial  resources
necessary to enforce the patent  rights that we hold.  No assurance  can be made
that our patents will provide  competitive  advantages  for our products or will
not be successfully  challenged by  competitors.  No assurance can be given that
patents do not exist or could not be filed which would have a materially adverse
effect on our ability to develop or market our products or to obtain or maintain
any competitive  position that we may achieve with respect to our products.  Our
patents also may not prevent others from developing  competitive  products using
related technology.



 12



There can be no assurance that we will be able to obtain  necessary  licenses if
we cannot enforce  patent rights we may hold. In addition,  the failure of third
parties from whom we currently license certain  proprietary  information or from
whom we may be  required to obtain such  licenses in the future,  to  adequately
enforce their rights to such proprietary information, could adversely affect the
value of such licenses to us.

         If we cannot  enforce  the patent  rights we  currently  hold we may be
required to obtain  licenses from others to develop,  manufacture  or market our
products.  There can be no  assurance  that we would be able to obtain  any such
licenses on  commercially  reasonable  terms,  if at all. We  currently  license
certain proprietary  information from third parties, some of which may have been
developed  with  government  grants  under  circumstances  where the  government
maintained certain rights with respect to the proprietary information developed.
No assurances can be given that such third parties will  adequately  enforce any
rights they may have or that the rights, if any, retained by the government will
not adversely affect the value of our license.

         There is no guarantee  that our trade  secrets will not be disclosed or
known by our competitors.

         To protect our rights,  we require certain employees and consultants to
enter into  confidentiality  agreements  with us. There can be no assurance that
these  agreements  will  not be  breached,  that  we  would  have  adequate  and
enforceable  remedies for any breach, or that any trade secrets of ours will not
otherwise become known or be independently developed by competitors.

We have  limited  marketing  and sales  capability.  If we are  unable to obtain
additional  distributors  and our current and future  distributors do not market
our products  successfully,  we may not generate  significant revenues or become
profitable.

         We have limited marketing and sales  capability.  We are dependent upon
existing and, possibly future, marketing agreements and third party distribution
agreements for our products in order to generate significant revenues and become
profitable.  As a result, any revenues received by us will be dependent in large
part on the  efforts  of third  parties,  and there is no  assurance  that these
efforts will be successful.

         Our   commercialization   strategy  for   Ampligen(R)-CFS  may  include
licensing/co-marketing  agreements  utilizing the resources and  capacities of a
strategic  partner(s).  We are currently seeking worldwide marketing partner(s),
with the goal of having a relationship in place before approval is obtained.  In
parallel to partnering discussions, appropriate pre-marketing activities will be
undertaken.  We intend to control  manufacturing  of  Ampligen  on a  world-wide
basis.

         We cannot  assure that our U.S. or foreign  marketing  strategy will be
successful or that we will be able to establish  future marketing or third party
distribution  agreements  on  terms  acceptable  to us,  or  that  the  cost  of
establishing  these  arrangements  will not exceed  any  product  revenues.  Our
inability to establish viable marketing and sales capabilities would most likely
have a materially adverse effect on us.
 13
There are no long-term  agreements with suppliers of required  materials.  If we
are unable to obtain the  required  raw  materials,  we may be required to scale
back  our  operations  or  stop  manufacturing  Alferon  N  Injection(R)  and/or
Ampligen(R).

         A number of essential materials are used in the production of Alferon N
Injection(R),  including  human  white  blood  cells.  We do not have  long-term
agreements for the supply of any of such materials. There can be no assurance we
can enter into  long-term  supply  agreements  covering  essential  materials on
commercially reasonable terms, if at all.

         There  are a limited  number  of  manufacturers  in the  United  States
available  to provide the  polymers  for use in  manufacturing  Ampligen(R).  At
present,  we do not have any agreements with third parties for the supply of any
of these polymers. We have established relevant manufacturing  operations within
our New  Brunswick,  New  Jersey  facility  for the  production  of  Ampligen(R)
polymers  from raw  materials in order to obtain  polymers on a more  consistent
manufacturing basis.

         If we are unable to obtain or manufacture the required polymers, we may
be required to scale back our  operations or stop  manufacturing.  The costs and
availability of products and materials we need for the production of Ampligen(R)
and the commercial production of Alferon N Injection(R) and other products which
we may commercially produce are subject to fluctuation depending on a variety of
factors  beyond  our  control,   including   competitive  factors,   changes  in
technology,  and FDA and  other  governmental  regulations  and  there can be no
assurance  that we will be able to obtain such  products and  materials on terms
acceptable to us or at all.

There is no assurance that  successful  manufacture of a drug on a limited scale
basis  for  investigational  use  will  lead  to  a  successful   transition  to
commercial, large-scale production.

         Small  changes  in  methods  of  manufacturing,   including  commercial
scale-up,  may affect the chemical structure of Ampligen(R) and other RNA drugs,
as well as their safety and efficacy,  and can, among other things,  require new
clinical studies and affect orphan drug status, particularly, market exclusivity
rights,  if any,  under  the  Orphan  Drug  Act.  The  transition  from  limited
production of  pre-clinical  and clinical  research  quantities to production of
commercial  quantities  of our products  will involve  distinct  management  and
technical  challenges  and will  require  additional  management  and  technical
personnel and capital to the extent such  manufacturing  is not handled by third
parties.  There can be no assurance that our manufacturing will be successful or
that any given product will be determined to be safe and  effective,  capable of
being  manufactured   economically  in  commercial  quantities  or  successfully
marketed.
 14
We have limited manufacturing experience and capacity.

         Ampligen(R) has been only produced in limited quantities for use in our
clinical   trials  and  we  are  dependent  upon  a  third  party  supplier  for
substantially  all of the  production  process.  The failure to  continue  these
arrangements or to achieve other such  arrangements on satisfactory  terms could
have a material  adverse affect on us. Also to be successful,  our products must
be  manufactured   in  commercial   quantities  in  compliance  with  regulatory
requirements  and at  acceptable  costs.  To the extent we are  involved  in the
production  process,  our current facilities are not adequate for the production
of our proposed products for large-scale commercialization,  and we currently do
not have adequate personnel to conduct commercial-scale manufacturing. We intend
to  utilize  third-party  facilities  if and when the need  arises or, if we are
unable to do so, to build or acquire commercial-scale  manufacturing facilities.
We will  need to  comply  with  regulatory  requirements  for  such  facilities,
including  those of the FDA pertaining to current Good  Manufacturing  Practices
("cGMP")  regulations.  There can be no assurance  that such  facilities  can be
used,  built,  or  acquired  on  commercially  acceptable  terms,  or that  such
facilities,  if used,  built,  or acquired,  will be adequate for our  long-term
needs.  Please refer to the Risk Factor "Our Alferon N  Injection(R)  commercial
sales have halted due to lack of finished goods inventory."

We may not be profitable unless we can produce  Ampligen(R) or other products in
commercial quantities at costs acceptable to us.

         We have  never  produced  Ampligen(R)  or any other  products  in large
commercial  quantities.  We must  manufacture  our products in  compliance  with
regulatory  requirements in large commercial  quantities and at acceptable costs
in order for us to be profitable. We intend to utilize third-party manufacturers
and/or  facilities if and when the need arises or, if we are unable to do so, to
build  or  acquire  commercial-scale  manufacturing  facilities.  If  we  cannot
manufacture  commercial  quantities  of  Ampligen(R)  or enter into third  party
agreements for its manufacture at costs acceptable to us, our operations will be
significantly  affected.  Also, each production lot of Alferon N Injection(R) is
subject to FDA review and approval prior to releasing the lots to be sold.  This
review and approval process could take considerable  time, which would delay our
having product in inventory to sell.

Rapid technological change may render our products obsolete or non-competitive.

         The  pharmaceutical  and biotechnology  industries are subject to rapid
and   substantial   technological   change.   Technological   competition   from
pharmaceutical and biotechnology companies, universities,  governmental entities
and others  diversifying  into the field is intense and is expected to increase.
Most of these  entities  have  significantly  greater  research and  development
capabilities than us, as well as substantial marketing, financial and managerial
resources,  and  represent  significant  competition  for  us.  There  can be no
assurance  that   developments  by  others  will  not  render  our  products  or
technologies  obsolete  or  noncompetitive  or that we will be able to keep pace
with technological developments.

Our products may be subject to substantial competition.

         Ampligen(R). Competitors may be developing technologies that are, or in
the future may be, the basis for competitive  products.  Some of these potential
products  may have an  entirely  different  approach  or means of  accomplishing
similar  therapeutic  effects to products being developed by us. These competing
products may be more  effective and less costly than our products.  In addition,
conventional drug therapy,  surgery and other more familiar treatments may offer
competition  to  our  products.   Furthermore,  many  of  our  competitors  have
significantly  greater  experience  than us in  pre-clinical  testing  and human
clinical trials of  pharmaceutical  products and in obtaining FDA, HPB and other
regulatory  approvals of products.  Accordingly,  our competitors may succeed in
obtaining FDA, HPB or other regulatory  product  approvals more rapidly than us.
 15
There are no drugs approved for commercial  sale with respect to treating ME/CFS
in the United  States.  The  dominant  competitors  with drugs to treat  disease
indications in which we plan to address include Gilead  Pharmaceutical,  Pfizer,
Bristol-Myers,  Abbott Labs,  GlaxoSmithKline,  Merck and Schering-Plough  Corp.
These potential  competitors are among the largest  pharmaceutical  companies in
the world,  are well known to the public  and the  medical  community,  and have
substantially   greater   financial   resources,    product   development,   and
manufacturing and marketing  capabilities than we have.  Although we believe our
principal  advantage  is the unique  mechanism of action of  Ampligen(R)  on the
immune system, we cannot assure that we will be able to compete.

         ALFERON  N   Injection(R).   Our  competitors  are  among  the  largest
pharmaceutical  companies  in the  world,  are well  known to the public and the
medical community,  and have substantially greater financial resources,  product
development,  and manufacturing and marketing capabilities than we have. Alferon
N Injection(R)  currently competes with Schering's injectable  recombinant alpha
interferon  product  (INTRON(R)  A) for  the  treatment  of  genital  warts.  3M
Pharmaceuticals  also  offer  competition  from  its  immune-response  modifier,
Aldara(R),  a  self-administered  topical  cream,  for the treatment of external
genital and  perianal  warts.  In  addition,  Medigene  has FDA  approval  for a
self-administered  ointment,  VeregenTM,  which  is  indicated  for the  topical
treatment of external  genital and perianal warts.  Alferon N Injection(R)  also
competes with surgical,  chemical,  and other methods of treating genital warts.
We cannot assess the impact products  developed by our competitors,  or advances
in other methods of the treatment of genital warts,  will have on the commercial
viability of Alferon N Injection(R).  If and when we obtain additional approvals
of uses of this product,  we expect to compete primarily on the basis of product
performance.  Our competitors have developed or may develop products (containing
either  alpha  or beta  interferon  or  other  therapeutic  compounds)  or other
treatment  modalities for those uses.  There can be no assurance that, if we are
able to obtain  regulatory  approval of Alferon N Injection(R) for the treatment
of new indications,  we will be able to achieve any significant penetration into
those  markets.  In  addition,  because  certain  competitive  products  are not
dependent  on a source of human blood  cells,  such  products  may be able to be
produced  in greater  volume and at a lower  cost than  Alferon N  Injection(R).
Currently,  our wholesale price on a per unit basis of Alferon N Injection(R) is
higher  than  that of the  competitive  recombinant  alpha  and beta  interferon
products.

         General.  Other  companies may succeed in developing  products  earlier
than we do, obtaining approvals for such products from the FDA more rapidly than
we do, or developing products that are more effective than those we may develop.
While we will  attempt  to expand  our  technological  capabilities  in order to
remain  competitive,  there can be no assurance that research and development by
others or other  medical  advances  will not render our  technology  or products
obsolete or  non-competitive  or result in treatments  or cures  superior to any
therapy we develop.



 16



Possible  side effects  from the use of  Ampligen(R)  or Alferon N  Injection(R)
could adversely affect potential revenues and physician/patient acceptability of
our product.

         Ampligen(R).  We  believe  that  Ampligen(R)  has been  generally  well
tolerated  with a low  incidence of clinical  toxicity,  particularly  given the
severely  debilitating or life  threatening  diseases that have been treated.  A
mild  flushing  reaction has been observed in  approximately  15-20% of patients
treated in our various studies.  This reaction is occasionally  accompanied by a
rapid heart beat,  a tightness of the chest,  urticaria  (swelling of the skin),
anxiety,  shortness of breath, subjective reports of "feeling hot", sweating and
nausea.  The  reaction is usually  infusion-rate  related and can  generally  be
controlled by reducing the rate of infusion.  Other adverse side effects include
liver enzyme level elevations,  diarrhea,  itching,  asthma, low blood pressure,
photophobia, rash, transient visual disturbances,  slow or irregular heart rate,
decreases  in  platelets  and  white  blood  cell  counts,  anemia,   dizziness,
confusion,  elevation of kidney function tests,  occasional  temporary hair loss
and various flu-like symptoms, including fever, chills, fatigue, muscular aches,
joint  pains,  headaches,  nausea and  vomiting.  These  flu-like  side  effects
typically  subside  within  several  months.  One or more of the potential  side
effects might deter usage of  Ampligen(R)  in certain  clinical  situations  and
therefore,  could  adversely  affect  potential  revenues and  physician/patient
acceptability of our product.

         Alferon N  Injection(R).  At present,  Alferon N  Injection(R)  is only
approved for the  intra-lesional  (within the lesion) treatment of refractory or
recurring external genital warts in adults. In clinical trials conducted for the
treatment  of  genital  warts  with  Alferon N  Injection(R),  patients  did not
experience  serious  side  effects;  however,  there  can be no  assurance  that
unexpected or unacceptable side effects will not be found in the future for this
use or other  potential uses of Alferon N  Injection(R)  which could threaten or
limit such product's usefulness.

We may be subject  to  product  liability  claims  from the use of  Ampligen(R),
Alferon N Injection(R),  or other of our products which could negatively  affect
our  future  operations.  We have  temporarily  discontinued  product  liability
insurance.

         We face an inherent  business  risk of  exposure  to product  liability
claims in the event that the use of Ampligen(R) or other of our products results
in adverse  effects.  This  liability  might result from claims made directly by
patients,  hospitals, clinics or other consumers, or by pharmaceutical companies
or others  manufacturing these products on our behalf. Our future operations may
be negatively  affected from the litigation costs,  settlement expenses and lost
product  sales  inherent to these  claims.  While we will continue to attempt to
take appropriate  precautions,  we cannot assure that we will avoid  significant
product liability exposure.

         On November 28, 2008,  as we disclosed in an 8-K, we suspended  product
liability insurance for Alferon(R) N and Ampligen(R) until we receive regulatory
clearance  for  Ampligen(R).  We now require  third  parties to  indemnify us in
conjunction with all overseas emergency sales of Ampligen(R) and Alferon(R) LDO.
We concluded that years of successfully addressing the limited number of product
liability claims filed against Ampligen(R) and Alferon(R) LDO, combined with the
mandatory patient waivers completed as an element of clinical trials and lack of
any  commercial  sales since  April 2008,  that  temporarily  discontinuing  the
liability  insurance  was an acceptable  risk given our financial  condition and
need to conserve cash.
 17
         Currently,  without  product  liability  coverage for  Ampligen(R)  and
Alferon(R)  LDO, a claim  against the products  could have a materially  adverse
effect on our business and financial condition.

The loss of services of key personnel including Dr. William A. Carter could hurt
our chances for success.

         Our  success  is  dependent  on the  continued  efforts  of our  staff,
especially  certain doctors and researchers  along with the continued efforts of
Dr.  William  A.  Carter  because of his  position  as a pioneer in the field of
nucleic acid drugs, his being the co-inventor of Ampligen(R),  and his knowledge
of our overall activities, including patents and clinical trials. As a result of
our  implementation of the Employee Wage Or Hours Reduction  Program,  our staff
has  agreed  to take a portion  of their  compensation  in shares of our  Common
Stock. While we believe that our employees are dedicated to us and while we have
incentivised  them to remain with us through the  establishment  of a Bonus Pool
that  would  award them  money in the event  that the FDA  approves  our NDA for
Ampligen(R),  we cannot  assure  that they will  remain with us. The loss of the
services of personnel key to our  operations or Dr. Carter could have a material
adverse effect on our operations and chances for success. As a cash conservation
measure, we have elected to discontinue the key man life insurance in the amount
of $2,000,000 on the life of Dr.  Carter until we receive  regulatory  clearance
for  Ampligen(R).  An  employment  agreement  continues to exist with Dr. Carter
that,  as amended,  runs until  December 31, 2010.  However,  Dr. Carter has the
right to  terminate  his  employment  upon not less than 30 days  prior  written
notice.  The loss of Dr.  Carter or other  personnel  or the  failure to recruit
additional  personnel as needed could have a  materially  adverse  effect on our
ability to achieve our objectives.

Uncertainty of health care reimbursement for our products.

         Our ability to successfully  commercialize our products will depend, in
part,  on the extent to which  reimbursement  for the cost of such  products and
related  treatment  will be  available  from  government  health  administration
authorities,   private  health  coverage   insurers  and  other   organizations.
Significant  uncertainty exists as to the reimbursement status of newly approved
health care products,  and from time to time legislation is proposed,  which, if
adopted,   could  further   restrict  the  prices   charged  by  and/or  amounts
reimbursable to  manufacturers  of  pharmaceutical  products.  We cannot predict
what,  if any,  legislation  will  ultimately  be  adopted or the impact of such
legislation  on us.  There  can  be no  assurance  that  third  party  insurance
companies will allow us to charge and receive  payments for products  sufficient
to realize an appropriate return on our investment in product development.

There are  risks of  liabilities  associated  with  handling  and  disposing  of
hazardous materials.

         Our  business  involves  the  controlled  use of  hazardous  materials,
carcinogenic  chemicals,  flammable solvents and various radioactive  compounds.
Although we believe that our safety  procedures  for  handling and  disposing of
such materials comply in all material respects with the standards  prescribed by
applicable  regulations,  the risk of  accidental  contamination  or injury from
these  materials  cannot  be  completely  eliminated.  In the  event  of such an
accident or the failure to comply with applicable regulations,  we could be held
liable for any damages that result, and any such liability could be significant.
We do not maintain insurance coverage against such liabilities.
 18
Risks Associated With an Investment in Our Common Stock

The market price of our stock may be adversely affected by market volatility.

         The  market  price of our  common  stock  has been and is  likely to be
volatile.  This is especially true given the current significant  instability in
the financial  markets.  In addition to general  economic,  political and market
conditions,  the price and trading volume of our stock could fluctuate widely in
response to many factors, including:

     o    announcements  of  the  results  of  clinical  trials  by  us  or  our
          competitors;

     o    adverse reactions to products;

     o    governmental  approvals,  delays in expected governmental approvals or
          withdrawals  of  any  prior   governmental   approvals  or  public  or
          regulatory  agency concerns  regarding the safety or  effectiveness of
          our products;

     o    changes in U.S.  or  foreign  regulatory  policy  during the period of
          product development;

     o    developments  in patent or other  proprietary  rights,  including  any
          third party challenges of our intellectual property rights;

     o    announcements of technological innovations by us or our competitors;

     o    announcements   of  new  products  or  new  contracts  by  us  or  our
          competitors;

     o    actual or anticipated  variations in our operating  results due to the
          level of development expenses and other factors;

     o    changes in financial  estimates by securities analysts and whether our
          earnings meet or exceed the estimates;

     o    conditions and trends in the pharmaceutical and other industries;

     o    new accounting standards; o overall investment market fluctuation; and

     o    occurrence of any of the risks described in these "Risk Factors."

         Our common stock is listed for  quotation  on the NYSE Amex  (formerly,
the American Stock  Exchange).  For the 12-month period ended December 31, 2008,
the price of our  common  stock has ranged  from  $0.25 to $1.20 per  share.  We
expect the price of our  common  stock to remain  volatile.  The  average  daily
trading  volume of our common stock varies  significantly.  Our  relatively  low
average  volume and low average  number of  transactions  per day may affect the
ability  of our  stockholders  to sell  their  shares  in the  public  market at
prevailing prices and a more active market may never develop.

         In the past, following periods of volatility in the market price of the
securities of companies in our industry,  securities class action litigation has
often been instituted  against companies in our industry.  If we face securities
litigation in the future, even if without merit or unsuccessful, it would result
in  substantial  costs and a diversion of management  attention  and  resources,
which would negatively impact our business.

The sale of our common stock to Fusion  Capital may cause  dilution and the sale
of the shares of common stock  acquired by Fusion  Capital could cause the price
of our common stock to decline.

         In connection  with entering  into the Purchase  Agreement  with Fusion
Capital,  we  registered  21,300,000  shares  in the  aggregate,  consisting  of
20,000,000  shares which we may sell to Fusion  Capital and 1,300,000  shares we
have issued or may issue to Fusion  Capital as a commitment  fee. As of the date
of this  Prospectus  we have sold an  aggregate  of  4,377,515  shares to Fusion
Capital  (exclusive of any shares issued as a commitment fee) under the Purchase
Agreement for gross proceeds of  approximately  $1,860,000,  leaving  15,622,485
shares (exclusive of additional shares issuable as a commitment fee). The number
of shares ultimately offered for sale by Fusion Capital under this Prospectus is
dependent  upon the  number of shares  purchased  by  Fusion  Capital  under the
agreement.  The purchase price for the common stock to be sold to Fusion Capital
pursuant to the  Purchase  Agreement  will  fluctuate  based on the price of our
common stock. It is anticipated  that shares offered pursuant to this Prospectus
could be sold over a period of up to 16 months after the date hereof.  Depending
upon market  conditions  at the time, a sale of shares by Fusion  Capital at any
given time could cause the trading price of our common stock to decline.  Fusion
Capital may  ultimately  purchase  all,  some or none of the  15,622,485  shares
(exclusive  of  additional  shares  issued or to be issued as a commitment  fee)
registered herein but not yet issued.  After it has acquired such shares, it may
sell all, some or none of such shares. Therefore,  sales to Fusion Capital by us
under the Purchase Agreement may result in substantial dilution to the interests
of other holders of our common stock. The sale of a substantial number of shares
of our common stock by Fusion Capital, or anticipation of such sales, could make
it more  difficult  for us to sell equity or  equity-related  securities  in the
future at a time and at a price that we might  otherwise  wish to effect  sales.
However,  we have the right to control the timing and amount of any sales of our
shares to Fusion  Capital and the  agreement may be terminated by us at any time
at our discretion without any cost to us.

         In  addition  to the  shares  registered  for Fusion  Capital,  we have
previously  registered  135% of  3,615,514  shares  issuable  upon  exercise  of
Warrants  related to our former  convertible  debentures and  14,442,294  shares
issuable  upon exercise of certain  other  warrants.  To the extent the exercise
price of the  warrants is less than the market  price of the common  stock,  the
holders of the  warrants  are likely to  exercise  them and sell the  underlying
shares of common stock and to the extent that the conversion  price and exercise
price of these securities are adjusted pursuant to anti-dilution protection, the
securities  could be exercisable  or convertible  for even more shares of common
stock.  We also may issue shares to be used to meet our capital  requirements or
use  shares to  compensate  employees,  consultants  and/or  directors.  In this
regard,  we  previously  registered  $50,000,000  worth of our  securities  in a
universal  shelf  registration  statement,  none of which has been designated or
issued.  We are unable to estimate the amount,  timing or nature of future sales
of outstanding  common stock or instruments  convertible into or exercisable for
our common stock.

         Sales of  substantial  amounts of our common stock in the public market
could cause the market price for our common stock to  decrease.  Furthermore,  a
decline in the price of our common  stock  would  likely  impede our  ability to
raise capital through the issuance of additional shares of common stock or other
equity securities.
 20
Provisions of our  Certificate of  Incorporation  and Delaware law could defer a
change of our management which could discourage or delay offers to acquire us.

         Provisions of our  Certificate  of  Incorporation  and Delaware law may
make  it  more  difficult  for  someone  to  acquire  control  of us or for  our
stockholders to remove existing  management,  and might discourage a third party
from offering to acquire us, even if a change in control or in management  would
be beneficial to our stockholders. For example, our Certificate of Incorporation
allows us to issue shares of preferred  stock without any vote or further action
by our  stockholders.  Our  Board  of  Directors  has the  authority  to fix and
determine the relative rights and preferences of preferred  stock.  Our Board of
Directors  also has the  authority  to issue  preferred  stock  without  further
stockholder  approval.  As a result,  our Board of Directors could authorize the
issuance  of a series  of  preferred  stock  that  would  grant to  holders  the
preferred right to our assets upon  liquidation,  the right to receive  dividend
payments before dividends are distributed to the holders of common stock and the
right to the  redemption of the shares,  together  with a premium,  prior to the
redemption of our common stock.  In this regard,  in November 2002, we adopted a
stockholder  rights plan and, under the Plan, our Board of Directors  declared a
dividend distribution of one Right for each outstanding share of Common Stock to
stockholders of record at the close of business on November 29, 2002. Each Right
initially  entitles  holders to buy one unit of preferred stock for $30.00.  The
Rights generally are not  transferable  apart from the common stock and will not
be exercisable unless and until a person or group acquires or commences a tender
or exchange offer to acquire,  beneficial ownership of 15% or more of our common
stock.  However,  for Dr.  Carter,  our Chief  Executive  Officer,  who  already
beneficially  owns 8.9% of our common stock,  the Plan's  threshold will be 20%,
instead of 15%. The Rights will expire on November 19, 2012, and may be redeemed
prior thereto at $.01 per Right under certain circumstances.

         Because the risk factors  referred to above could cause actual  results
or outcomes to differ  materially  from those  expressed in any  forward-looking
statements  made  by us,  you  should  not  place  undue  reliance  on any  such
forward-looking  statements.  Further, any forward-looking statement speaks only
as of the date on which it is made and we undertake no  obligation to update any
forward-looking statement or statements to reflect events or circumstances after
the  date on  which  such  statement  is  made  or  reflect  the  occurrence  of
unanticipated  events.  New  factors  emerge  from  time to time,  and it is not
possible for us to predict which will arise.  In addition,  we cannot assess the
impact of each  factor on our  business  or the extent to which any  factor,  or
combination of factors, may cause actual results to differ materially from those
contained in any  forward-looking  statements.  Our research in clinical efforts
may continue for the next several  years and we may continue to incur losses due
to clinical  costs incurred in the  development  of  Ampligen(R)  for commercial
application Possible losses may fluctuate from quarter to quarter as a result of
differences  in the  timing of  significant  expenses  incurred  and  receipt of
licensing fees and/or cost recovery treatment revenue.

The following  table  presents  information  regarding the selling  stockholder,
Fusion  Capital.  Neither the selling  stockholder nor any of its affiliates has
held a position  or office,  or had any other  material  relationship,  with us.
However,  in July 2005 we entered into a prior common stock  purchase  agreement
with Fusion Capital,  pursuant to which we sold an aggregate of 8,791,838 shares
for total gross proceeds of  $20,000,000.  In April 2006 we entered into a prior
common stock purchase  agreement with Fusion Capital,  pursuant to which we sold
an  aggregate of  10,682,032  shares for total gross  proceeds of  approximately
$19,739,000 through November, 2007. Each of these transactions was substantially
similar to the transaction set forth herein.

(1)      Applicable percentage of ownership is based on 74,960,278 shares of our

         commencement of the offering),  together with securities exercisable or
         convertible  into shares of Common Stock within sixty (60) days of that
         date for the selling stockholder. Beneficial ownership is determined in
         accordance  with the rules of the SEC and generally  includes voting or
         investment power with respect to securities. Shares of common stock are
         deemed to be  beneficially  owned by the person holding such securities
         for the  purpose of  computing  the  percentage  of  ownership  of such
         person, but are not treated as outstanding for the purpose of computing
         the percentage ownership of any other person.

(2)      Steven G. Martin and Joshua B. Scheinfeld, the principals of Fusion

         the shares of common stock owned by Fusion Capital. Messrs. Martin and
         Scheinfeld have shared voting and disposition power
         over the shares being offered under this Prospectus.

(3)      We have included in this Prospectus 21,300,000 shares in the aggregate.
         The numbers in the above  table are as of August 1, 2008,  prior to the
         commencement  of the offering.  As of the date of the  Prospectus,  the
         21,300,000  shares consist of the  following:4,377,515  shares which we
         have issued and sold to Fusion Capital, 15,622,485 shares which are not
         presently  issued  and  which  we may  sell to  Fusion  Capital  at our
         discretion,  690,300  shares  we have  issued to  Fusion  Capital  as a
         commitment  fee and 609,700  shares we may issue to Fusion Capital as a
         commitment  fee.  Therefore,  we may issue to Fusion  Capital  up to an
         additional  16,232,185  shares under the Purchase  Agreement but Fusion
         Capital does not presently  beneficially own those shares as determined
         in  accordance  with the rules of the SEC.  Prior to entering  into the
         Purchase  Agreement  Fusion Capital owned 448,814 of our shares that it
         previously acquired.

                             The Fusion Transaction

General

         On July 2, 2008, we entered into a Common Stock Purchase Agreement with
Fusion Capital Fund II, LLC, an Illinois limited  liability  company.  Under the
Purchase Agreement,  Fusion Capital is obligated,  under certain conditions,  to
purchase shares from us in an aggregate amount of up to $30 million from time to
time  over a 25 month  period  from  August  21,  2008.  Under  the terms of the
Purchase  Agreement,  Fusion Capital has received a commitment fee consisting of
650,000 shares of our common stock.  Also, we will issue to Fusion Capital up to
an additional  650,000 shares as a commitment fee pro rata as we receive the $30
million of future funding. We originally  registered herein 21,300,000 shares in
the  aggregate,  consisting  of  20,000,000  shares  which we may sell to Fusion
Capital and 1,300,000  shares we have issued or may issue to Fusion Capital as a
commitment  fee. As of April 23,  2009,  we have sold an  aggregate of 4,377,515
shares to Fusion  Capital  (exclusive of any shares issued as a commitment  fee)
under the Purchase Agreement for gross proceeds of approximately $1,860,000.

         Our common  stock is quoted on the NYSE Amex  (formerly,  the  American
Stock  Exchange)  under the symbol "HEB." In connection  with this  transaction,
under the rules of the NYSE Amex, we may not issue more than  14,823,651  shares
(19.99% of our  outstanding  shares as of July 2, 2008, the date of the Purchase
Agreement)  without first obtaining the approval of our stockholders.  Under the
Purchase  Agreement and a Registration  Rights  Agreement with Fusion Capital we
are  required to register  and have  included in the  offering  pursuant to this
Prospectus (1) 650,000 shares which have already been issued,  (2) an additional
650,000  shares which we may issue in the future as a commitment fee pro rata as
we receive up to the $30 million of future  funding and (3) at least  13,523,651
shares which we may sell to Fusion Capital after this registration  statement is
declared  effective.  In the  aggregate,  this is  14,823,651  or  19.99% of our
outstanding shares on July 2, 2008, the date of the Purchase Agreement.

         Under the Purchase Agreement,  we have the right but not the obligation
to sell  more  than the  20,000,000  shares to  Fusion  Capital  (excluding  the
1,300,000  shares we have issued or may issue to Fusion  Capital as a commitment
fee). This 21,300,000 shares is greater than 19.99% of our outstanding shares of
common  stock as of the date of the  Purchase  Agreement.  The  number of shares
ultimately  offered for sale by Fusion  Capital is dependent  upon the number of
shares purchased by Fusion Capital under the Purchase Agreement. On November 11,
2008, at our Annual Meeting of Stockholders we received  stockholder approval of
the  Purchase  Agreement in order to be in  compliance  with the NYSE Amex rules
permitting us to sell more than 14,823,651 or 19.99% of our  outstanding  shares
on July 2, 2008, the date of the Purchase Agreement.

         As of the date of this  Prospectus,  we do not have any plans or intent
to sell to Fusion Capital any shares beyond the 20,000,000 shares offered hereby
(excluding the 1,300,000 shares we have issued or may issue to Fusion Capital as
a commitment fee). However, if we elect to sell more than the 20,000,000 shares,
which we have the right but not the  obligation  to do, we must  first  register
under the Securities  Act any  additional  shares we may elect to sell to Fusion
Capital before we can sell such additional shares, which could cause substantial
dilution to our stockholders.

         Generally,  we have the right but not the obligation  from time to time
to sell our  shares to Fusion  Capital  in  amounts  between  $120,000  and $1.0
million depending on certain conditions. We have the right to control the timing
and amount of any sales of our shares to Fusion  Capital.  The purchase price of
 24
the shares will be determined  based upon the market price of our shares without
any fixed  discount at the time of each sale.  Fusion  Capital does not have the
right nor the  obligation  to  purchase  any shares of our  common  stock on any
business  day that the price of our common  stock is below  $0.40.  There are no
negative  covenants,  restrictions on future  fundings,  penalties or liquidated
damages in the Purchase  Agreement or the  Registration  Rights  Agreement.  The
Purchase Agreement may be terminated by us at any time at our discretion without
any cost to us.

         The number of shares  ultimately  offered for sale by Fusion Capital is
dependent  upon the  number of shares  purchased  by  Fusion  Capital  under the
Purchase Agreement.

Purchase Of Shares Under The Purchase Agreement

         Under the common stock purchase agreement, on any business day selected
by us, we may direct  Fusion  Capital to  purchase  up to $120,000 of our common
stock. The purchase price per share is equal to the lesser of:

o        the lowest sale price of our common stock on the purchase date; or

o        the average of the three (3) lowest  closing  sale prices of our common
         stock  during the twelve (12)  consecutive  business  days prior to the
         date of a purchase by Fusion Capital.

         The purchase price will be equitably  adjusted for any  reorganization,
recapitalization,  non-cash dividend,  stock split, or other similar transaction
occurring  during the business days used to compute the purchase  price.  We may
direct Fusion  Capital to make multiple  purchases from time to time in our sole
discretion; no sooner then every two business days.

Our Right To Increase the Amount to be Purchased

                  In addition to purchases of up to $120,000  from time to time,
we may also from time to time elect on any single business day selected by us to
require  Fusion  Capital  to  purchase  our  shares in an amount up to  $150,000
provided  that our share price is not below $0.80 during the two  business  days
prior to and on the purchase date. We may increase this amount to up to $250,000
if our share price is not below $1.25 during the two business  days prior to and
on the purchase date. This amount may also be increased to up to $500,000 if our
share price is not below $1.75 during the two business  days prior to and on the
purchase  date.  This amount may also be  increased to up to  $1,000,000  if our
share price is not below $4.00 during the two business  days prior to and on the
purchase  date. We may direct Fusion  Capital to make multiple  large  purchases
from time to time in our sole  discretion;  however,  at least two business days
must have passed since the most recent large purchase was  completed.  The price
at which our common stock would be  purchased  in this type of larger  purchases
will be the  lesser of (i) the  lowest  sale  price of our  common  stock on the
purchase date and (ii) the lowest purchase price (as described above) during the
previous ten business days prior to the purchase date.

Minimum Purchase Price

         Under  the  common  stock  purchase  agreement,  we have set a  minimum
purchase price ("floor price") of $0.40.  However,  Fusion Capital does not have
the right nor the  obligation  to purchase any shares of our common stock in the
event  that the  purchase  price  would be less the floor  price.  Specifically,
Fusion Capital does not have the right or the  obligation to purchase  shares of
our common  stock on any  business day that the market price of our common stock
is below $0.40.
 25
Events of Default

         Generally,  Fusion  Capital may  terminate  the common  stock  purchase
agreement  without any liability or payment to us upon the  occurrence of any of
the following events of default:

o        the   effectiveness  of  the  registration   statement  of  which  this
         Prospectus  is a part of  lapses  for any  reason  (including,  without
         limitation,  the issuance of a stop order) or is  unavailable to Fusion
         Capital for sale of our common stock  offered  hereby and such lapse or
         unavailability  continues for a period of ten consecutive business days
         or for  more  than an  aggregate  of 30  business  days in any  365-day
         period;

o        suspension by the NYSE Amex of our common stock from trading for a
         period of three consecutive business days;

o        the  de-listing  of our common  stock from the NYSE Amex  provided  our
         common stock is not  immediately  thereafter  trading on the Nasdaq OTC
         Bulletin  Board Market,  the Nasdaq Global  Market,  the Nasdaq Capital
         Market, or the New York Stock Exchange;

o        the transfer  agent`s failure for five business days to issue to Fusion
         Capital  shares of our common stock which Fusion Capital is entitled to
         under the common stock purchase agreement;

o        any material breach of the  representations  or warranties or covenants
         contained  in the  common  stock  purchase  agreement  or  any  related
         agreements  which has or which could have a material  adverse effect on
         us subject to a cure period of five business days; or

o        any participation or threatened participation in insolvency or
         bankruptcy proceedings by or against us.

Our Termination Rights

         We have the  unconditional  right at any  time for any  reason  to give
notice to Fusion Capital  terminating the Purchase Agreement without any cost to
us.



 26



No Short-Selling or Hedging by Fusion Capital

         Fusion  Capital  has agreed that  neither it nor any of its  affiliates
shall  engage in any direct or indirect  short-selling  or hedging of our common
stock  during any time prior to the  termination  of the common  stock  purchase
agreement.

Effect of Performance of the Purchase Agreement on Our Stockholders

         All  21,300,000  shares  offered in this  Prospectus are expected to be
freely  tradable and will be sold over a period of up to 16 months from the date
of this Prospectus. The sale by Fusion Capital of a significant amount of shares
at any given time could  cause the market  price of our common  stock to decline
and to be highly  volatile.  We may sell to Fusion  Capital all, some or none of
the remaining  15,622,485 shares of common stock not yet sold or issued but part
of this offering.  After Fusion Capital has acquired any of such shares,  it may
sell all, some or none of such shares. Therefore,  sales to Fusion Capital by us
under the agreement may result in substantial dilution to the interests of other
holders of our common  stock.  However,  we have the right to control the timing
and amount of any sales of our shares to Fusion Capital and the agreement may be
terminated  by us at any time at our  discretion  without  any  cost to us.  The
number of  shares  ultimately  offered  for sale by Fusion  Capital  under  this
Prospectus is dependent  upon the number of shares  purchased by Fusion  Capital
under the  Purchase  Agreement.  The  following  table  sets forth the amount of
proceeds we would  receive from Fusion  Capital  from the sale of the  remaining
15,622,485 shares at varying purchase prices:

                              PLAN OF DISTRIBUTION

         The common stock offered by this  Prospectus is being offered by Fusion
Capital Fund II, LLC, the selling  stockholder.  The common stock may be sold or
distributed from time to time by the selling stockholder directly to one or more
purchasers or through  brokers,  dealers,  or underwriters who may act solely as
agents at market prices prevailing at the time of sale, at prices related to the
prevailing market prices, at negotiated prices, or at fixed prices, which may be
changed. The sale of the common stock offered by this Prospectus may be effected
in one or more of the following methods:

o        ordinary brokers' transactions;
o        transactions involving cross or block trades;
o        through brokers, dealers, or underwriters who may act solely as agents;
o        "at the market" into an existing market for the common stock;
o        in other  ways not  involving  market  makers or  established  business
         markets, including direct sales to purchasers or sales effected through
         agents;
o        in privately negotiated transactions; or
o        any combination of the foregoing.

         In order to comply  with the  securities  laws of  certain  states,  if
applicable,  the shares may be sold only through  registered or licensed brokers
or dealers.  In addition,  in certain states,  the shares may not be sold unless
they have been  registered  or  qualified  for sale in the state or an exemption
from the  registration  or  qualification  requirement is available and complied
with.

         Brokers,  dealers,   underwriters,   or  agents  participating  in  the
distribution  of the shares as agents may  receive  compensation  in the form of
commissions,  discounts,  or  concessions  from the selling  stockholder  and/or
purchasers of the common stock for whom the broker-dealers may act as agent. The
compensation paid to a particular broker-dealer may be less than or in excess of
customary commissions.

         Fusion Capital is an "underwriter" within the meaning of the Securities
Act.

         Neither we nor Fusion  Capital  can  presently  estimate  the amount of
compensation  that any agent will receive.  We know of no existing  arrangements
between Fusion Capital, any other stockholder,  broker, dealer,  underwriter, or
agent  relating  to the  sale or  distribution  of the  shares  offered  by this
Prospectus.  At the time a  particular  offer of  shares is made,  a  prospectus
supplement,  if required,  will be distributed  that will set forth the names of
any  agents,  underwriters,  or dealers  and any  compensation  from the selling
stockholder, and any other required information.

         We will pay all of the expenses incident to the registration, offering,
and sale of the shares to the public  other than  commissions  or  discounts  of
underwriters, broker-dealers, or agents. We have also agreed to indemnify Fusion
Capital and related persons against specified liabilities, including liabilities
under the Securities Act.
 28
         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to our directors,  officers,  and controlling  persons,  we
have been advised that in the opinion of the SEC this indemnification is against
public   policy  as  expressed  in  the   Securities   Act  and  is   therefore,
unenforceable.

         Fusion  Capital  and its  affiliates  have  agreed not to engage in any
direct or indirect  short selling or hedging of our common stock during the term
of the common stock purchase agreement.

         We  have  advised  Fusion  Capital  that  while  it  is  engaged  in  a
distribution  of the shares included in this Prospectus it is required to comply
with  Regulation M  promulgated  under the  Securities  Exchange Act of 1934, as
amended.   With  certain   exceptions,   Regulation  M  precludes   the  selling
stockholder,  any affiliated  purchasers,  and any broker-dealer or other person
who  participates  in  the  distribution  from  bidding  for or  purchasing,  or
attempting to induce any person to bid for or purchase any security which is the
subject  of  the  distribution  until  the  entire   distribution  is  complete.
Regulation M also prohibits any bids or purchases made in order to stabilize the
price of a security in connection with the distribution of that security. All of
the foregoing may affect the  marketability  of the shares  offered  hereby this
Prospectus.

         This  offering  will  terminate on the date that all shares  offered by
this Prospectus have been sold by Fusion Capital.


                                 USE OF PROCEEDS

         We will not receive any proceeds  from the sale of the shares of common
stock offered by the selling stockholder.  However, we may receive proceeds from
the sale of shares of our  common  stock to Fusion  Capital  under the  Purchase
Agreement.  We will apply such proceeds,  if any, to fund infrastructure  growth
including  manufacturing,  regulatory compliance,  market development or general
operating costs.

         SEC POSITION ON INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors,  officers or persons  controlling the company
pursuant to the foregoing provisions,  we have been informed that in the opinion
of the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is therefore unenforceable.


                   DESCRIPTION OF SECURITIES BEING REGISTERED

         The following  section does not purport to be complete and is qualified
in all respects by reference to the detailed  provisions of our  certificate  of
incorporation  and by-laws,  as amended and restated,  copies of which have been
filed with the Securities and Exchange Commission.
 29
         Our  authorized  capital  stock consist of: (i)  200,000,000  shares of
common stock,  $.001 par value;  and (ii) 5,000,000  shares of preferred  stock,
$.01 par value. 83,529,962 shares of common stock were issued and outstanding as
of the date of this Prospectus.

Common Stock

         Shares of our common stock are  entitled to one vote per share,  either
in person or by proxy,  on all  matters  that may be voted upon by the owners of
our shares at meetings of our stockholders. There is no provision for cumulative
voting with respect to the election of directors by the holders of common stock.
Therefore, the holder of more than 50% of our shares of outstanding common stock
can, if they choose to do so,  elect all of our  directors.  In this event,  the
holders of the  remaining  shares of common  stock will not be able to elect any
directors.

         The holders of common stock:

     o    have equal rights to dividends from funds legally available therefore,
          when and if declared by our board of directors;

     o    are  entitled  to share  ratably  in all of our assets  available  for
          distribution to holders of common stock upon liquidation,  dissolution
          or winding up of our affairs; and

     o    do not have preemptive  rights,  conversion  rights,  or redemption of
          sinking fund provisions.

         The outstanding shares of our common stock are duly authorized, validly
issued, fully paid and nonassessable.

Anti-Takeover Provisions

Delaware Law

         We are subject to the provisions of Section 203 of the Delaware General
Corporation Law, as amended,  which restricts certain business combinations with
interested  stockholders  even if such a combination  would be beneficial to all
stockholders.  In  general,  Section  203  would  require a  two-thirds  vote of
stockholders  for any business  combination  (such as a merger or sale of all or
substantially  all of our  assets)  between us and an  "interested  stockholder"
unless such transaction is approved by a majority of the disinterested directors
or meets certain other  requirements.  An "interested  stockholder"  is a person
who,  together with affiliates and associates,  owns (or within three years, did
own)  15%  or  more  of  our  voting  stock.   These  provisions  could  deprive
stockholders  of an  opportunity  to receive a premium for their common stock as
part of a sale of us or may  otherwise  discourage  a  potential  acquirer  from
attempting to obtain control of us.
 30
Certificate of Incorporation

         Provisions  of our  Certificate  of  Incorporation  may  make  it  more
difficult for someone to acquire control of us or for our stockholders to remove
existing management, and might discourage a third party from offering to acquire
us,  even if a change in control or in  management  would be  beneficial  to our
stockholders.  For example,  our Certificate of Incorporation allows us to issue
shares  of  preferred   stock  without  any  vote  or  further   action  by  our
stockholders.  Our Board of Directors has the authority to fix and determine the
relative rights and preferences of preferred  stock. Our Board of Directors also
has the authority to issue preferred stock without further stockholder approval.
As a result,  our Board of Directors could authorize the issuance of a series of
preferred  stock that would grant to holders the  preferred  right to our assets
upon  liquidation,  the right to receive dividend  payments before dividends are
distributed  to the holders of common stock and the right to the  redemption  of
the  shares,  together  with a premium,  prior to the  redemption  of our common
stock.

Shareholder rights plan

         In November,  2002 we adopted a shareholder  rights plan and, under the
Plan, our Board of Directors  declared a dividend  distribution of one Right for
each outstanding share of Common Stock to stockholders of record at the close of
business on November 29, 2002. Each Right initially  entitles holders to buy one
unit of preferred stock for $30.00.  The Rights  generally are not  transferable
apart  from the  common  stock and will not be  exercisable  unless  and until a
person or group  acquires or  commences  a tender or exchange  offer to acquire,
beneficial ownership of 15% or more of our common stock. However, for William A.
Carter,  M.D., our chief executive officer,  who already beneficial owns 8.9% of
our common stock,  the Plan's  threshold will be 20%, instead of 15%. The Rights
will expire on November 19, 2012,  and may be redeemed prior thereto at $.01 per
Right under certain circumstances.

         The rights have certain  anti-takeover  effects.  The rights will cause
substantial  dilution to a person or group that  attempts to acquire us on terms
not approved by our Board of Directors. The rights should not interfere with any
merger or business combination approved by the Board of Directors.


                                  LEGAL MATTERS
