Big Pharma: 2012-13′s Flu Vaccine Field

GlaxoSmithKline

U.K.-based GlaxoSmithKline (NYSE:GSK) is the manufacturer of the Fluarix vaccine (for ages 3 and up), as well as FluLaval.

Don’t get confused about the flu vaccine’s maker here. A company called ID Biomedical manufactures FluLaval, but that’s a subsidiary of Glaxo’s thanks to a 2006 acquisition.

Some experts predict $375 million worth of FluLaval sales this year, though again — not a big chunk considering GSK’s $27 billion in annual revenues.
