Reuters: U.S. has bought 195 million doses of H1N1 vaccine

The U.S. government has bought 195 million doses of H1N1 swine flu vaccine for a possible autumn vaccination campaign, a U.S. federal official said Thursday.

The U.S. Health and Human Services Department has also contracted for 120 million doses of adjuvant, a compound to stretch the number of doses of vaccine needed, the department's Dr. Robin Robinson told a meeting of Food and Drug Administration advisers.

Five companies are making H1N1 vaccine for the U.S. market -- AstraZeneca's MedImmune unit, Australia's CSL Ltd, GlaxoSmithKline Plc, Novartis AG and Sanofi-Aventis SA.

Earlier, an FDA official said vaccine makers were only getting about 30 percent as much vaccine from eggs as they usually get with seasonal influenza vaccine.
