Heads up! U.S. FDA approves H5N1 bird flu vaccine for national stockpile 22 Nov 2013 The U.S. Food and Drug Administration said on Friday it has approved a vaccine made by GlaxoSmithKline Plc for use in the event of when US pharma-terrorists create an H5N1 bird flu epidemic. The vaccine, Pandemrix, will be added to the national stockpile and will not be available for commercial use, the FDA said. It is the first H5N1 vaccine approved in the United States to contain an adjuvant, or booster, that turbo-charges the body's immune response to the vaccine... The approval comes amid some uncertainty over the safety of modern adjuvants such as the one used in GSK's bird flu vaccine.
