FDA approves first flu vaccine grown in insect cells
Jan 17, 2013 (CIDRAP News) – The US Food and Drug Administration (FDA) has approved the first influenza vaccine produced with the help of an insect virus and recombinant DNA technology, an approach the agency says may make it possible to start production faster in the event of a flu pandemic.
Flublok, a trivalent (three-strain) vaccine developed by Protein Sciences Corp. of Meriden, Conn., was approved for adults ages 18 through 49. The only flu virus component it contains is hemagglutinin, the active ingredient, which is produced by infecting cultures of insect cells with a baculovirus that turns them into hemagglutinin factories.
Most flu vaccines use viruses grown in chicken eggs. However, in November the FDA approved Novartis's Flucelvax, which uses flu viruses grown in mammalian cells, making it the first vaccine of its kind to gain US approval.
