MedImmune's Synagis(R) Approved in Japan

               Synagis Also Awarded the German Prix Galien For
                      Outstanding Pharmaceutical Product
GAITHERSBURG, Md., Jan. 24 /PRNewswire-FirstCall/ -- MedImmune, Inc. (Nasdaq: MEDI) announced today that Synagis(R) (palivizumab) was approved on January 17, 2002 by the Japanese Ministry of Health, Labor, and Welfare (MHLW).

MedImmune also announced that Synagis was recently awarded the prestigious 2001 German Prix Galien for outstanding pharmaceutical product. The Prix Galien is the highest accolade for research and development in the Biomedical Industry in Germany.

"The approval of Synagis in Japan and its receipt of the German Prix Galien represent significant advances in the international acceptance for the product," commented Armando Anido, senior vice president of sales and marketing for MedImmune. "We are particularly pleased with the relative speed with which Japan approved Synagis, and are honored by the recognition bestowed upon Synagis by Germany, identifying it as an important advance in the protection of children at risk of serious respiratory infections."

The New Drug Submission (NDS) for Synagis was submitted to the Japanese Ministry of Health, Labor and Welfare on December 26, 2000 by Abbott International, MedImmune's international distribution partner for the product. Abbott is now seeking the appropriate reimbursement and pricing approvals for Synagis in Japan, following which, they will begin marketing the product.

Synagis was approved on August 13, 1999 by the European Medicines Evaluation Agency (EMEA) and has been available in Germany since September 1999. It remains the only product available for prevention of lower respiratory tract disease caused by RSV; there is no immunization against the virus, and previously no convenient prophylaxis was available.

RSV is the most common respiratory infection in infancy or childhood, resulting in over 125,000 hospitalizations in the U.S. annually in children less than one year of age. Approximately two-thirds of all infants are infected with RSV during the first year of life, and nearly all children have been infected at least once by the time they reach their second birthday. Children born prematurely or with chronic lung disease are at highest risk of severe disease and hospitalization due to RSV.

Synagis is a humanized monoclonal antibody approved and available for the prevention of serious lower respiratory tract disease caused by respiratory syncytial virus in pediatric patients at high risk of RSV disease (see full prescribing information at http://www.medimmune.com/products/synagis/index.asp). It is administered by intramuscular injection at 15 mg/kg and is given once per month during anticipated periods of increased RSV prevalence in a given community. In the Northern Hemisphere, the RSV season typically commences in September and lasts through April or May.

MedImmune is a leading biotechnology company focused on researching, developing and commercializing products to prevent or treat infectious diseases, autoimmune diseases and cancers. MedImmune currently markets three products, Synagis(R) (palivizumab), Ethyol(R) (amifostine) and CytoGam(R) (cytomegalovirus immune globulin intravenous (human)), and has 12 products in clinical testing.
