    1 in 4 Americans Got Swine Flu Vaccine

    Rhode Island Most, Mississippi Least Protected From H1N1 Swine Flu

    Millions of Doses Go Unused continued...

    So far, between 81 million and 91 million doses have been given to between 72 million and 81 million U.S. residents (young children need two doses).

    That means a lot of vaccine is left over. Some of that vaccine, about 25 million doses, has already been donated to poor nations. But millions of doses of leftover vaccine will have to be thrown out. That isn't unusual -- lots of flu vaccine gets discarded every year -- but the scale is unprecedented.

    Schuchat defended the decision to purchase massive quantities of vaccine.

    "We had to decide: Do we want more than enough or less than enough? And we decided to protect the American people," she said.

    Since flu is unpredictable, CDC officials were very aware that the H1N1 vaccine supply would never match demand.

    "Early on, CDC Director [Thomas] Frieden predicted there would be times when we will have less H1N1 vaccine than we need and times we will have more than we need -- and 12 seconds when we will have exactly enough," Schuchat said.

    Schuchat pointed to the ongoing uptick in serious flu cases in Georgia as a reminder that people are still getting sick from H1N1 swine flu -- some of them very sick.

    While next year's seasonal flu vaccine will protect against H1N1 swine flu, it won't be ready until next fall. Over the summer and early fall, H1N1 swine flu will still be with us. And the new flu season is just starting in the Southern Hemisphere, where it will threaten unvaccinated residents as well as unvaccinated travelers.

    Based on CDC surveys, here are the state-by state H1N1 swine flu vaccination rates through January 2010 (rankings added by WebMD; CDC does not rank states):
