Europe fast-tracking swine flu vaccine

In a drive to inoculate people against swine flu before winter, many European governments say they will fast-track the testing of a vaccine, arousing concern among some experts about safety and proper doses. The European Medicines Agency, the EU's top drug regulatory body, is accelerating the approval process for swine flu vaccine, and countries such as Britain, Greece, France and Sweden say they'll start using the vaccine after it's greenlighted—possibly within weeks.
