WASHINGTON - The Food and Drug Administration has approved the new swine flu vaccine, a long-anticipated step as the U.S. government works to get vaccinations underway next month.

Health and Human Services Secretary Kathleen Sebelius announced the vaccine's approval to Congress today.

She says she hopes to get the first limited supplies distributed early in October.

The bulk of vaccine will start arriving Oct. 15, and Sebelius said eventually it should be available at 90,000 sites around the country.

Sebelius said there will be enough vaccine available for everyone eventually, but that certain people get at the front of the line -- including children and pregnant women.
