Sanofi ships H1N1 vaccine to U.S.

Sanofi-Aventis SA delivered its first shipment of swine-flu vaccine to the U.S. government on Sept. 29, according to a spokeswoman. Last week, the director of the U.S. Centers for Disease Control and Prevention said the first doses of an H1N1 vaccine should become available about Oct. 6. The company cautioned that the shots may not become immediately available for administration because they will have to work their way through government distribution channels.
