The U.S. Food and Drug Administration announced on September 15, 2009 that it has approved four vaccines against the H1N1 influenza virus for 2009. This approval will provide an important tool to fighting any Pandemic which may arise. The vaccines are to be distributed nationally within the next four weeks.
The Commissioner of Food and Drugs Margaret A. Hamburg, M.D. said, “Today’s approval is good news for our nation’s response to the 2009 H1N1 influenza virus. This vaccine will help protect individuals from serious illness and death from influenza.”
The FDA article reports that the vaccines are made by CSL Limited, MedImmune LLC, Novartis Vaccines and Diagnostics Limited, and sanofi pasteur Inc. All four firms manufacture the H1N1 vaccines using the same processes, which have a long record of producing safe seasonal influenza vaccines.
They report, “Clinical studies under way will provide additional information about the optimal dose in children. The recommendations for dosing will be updated if indicated by findings from those studies. The findings are expected in the near future.”
There are potential side effects and dangers but the vaccines have been well tolerated. Potential side effects are expected to be similar to those of seasonal flu vaccines. Dangers are indicated for anyone allergic to chicken eggs or any other allergies to ingrediants in the vaccine.
