PLANTATION, 
                      FL -- January 17, 2002 -- Viragen, Inc. and Viragen International, 
                      Inc. today announced the approval of its application to 
                      Swedish regulatory authorities to expand the use of Viragen's 
                      natural alpha interferon.
                    This 
                      broadened approval extends use of the drug to include the 
                      treatment of patients afflicted with any and all diseases 
                      in which patients were or became resistant to treatments 
                      using recombinant (synthetic) interferon. The most common 
                      maladies treated with interferons include hepatitis C, multiple 
                      sclerosis and certain cancers.
                    Viragen's 
                      natural alpha interferon had previously been approved in 
                      Sweden and certain other countries for the treatment of 
                      patients with hairy cell leukemia (HCL) and chronic myelogenous 
                      leukemia (CML) who did not respond to recombinant interferon 
                      regimens. Global interferon sales are estimated to exceed 
                      $2 billion per year.
                    Viragen's 
                      newly appointed chief medical officer, Professor Orjan Strannegard, 
                      MD, stated, "Recombinant interferon products are the dominant 
                      treatment for a broad range of chronic viral and malignant 
                      diseases. However, a significant percentage of patients 
                      cannot tolerate the adverse side-effects typically associated 
                      with recombinant regimens or fail the therapy, probably 
                      due to the formation of neutralizing antibodies. For those 
                      patients that do fail, there are few safe and effective 
                      alternatives. Our expanded Swedish approval provides further 
                      evidence that it may be advantageous for a patient to be 
                      treated with Viragen's naturally-derived interferon. This 
                      drug has been demonstrated to have excellent effects in 
                      various viral diseases and cancers. It is well tolerated 
                      by the treated patients and it is able to elicit a renewed 
                      response in patients that have been resistant to recombinant 
                      interferons."
                    Natural 
                      interferon, produced by white blood cells, is part of the 
                      human immune system. It is one of the body's natural defensive 
                      responses to foreign substances such as viruses, and is 
                      so named because it "interferes" with viral growth. Recombinant 
                      interferons, which currently dominate the interferon market, 
                      are genetically engineered and are sometimes recognized 
                      as "foreign" by the body's immune system. Recombinant interferons 
                      usually contain only one subtype of interferon as compared 
                      to multiple subtypes produced by human white blood cells.
