ATLANTA -- U.S. health officials say New England leads the nation in swine flu vaccinations -- while the South has the lowest rates.
Rhode Island has the highest vaccination rate -- at 39 percent. Mississippi has the lowest rate -- at 13 percent.
The report from the Centers for Disease Control and Prevention says many of the 13 other states with rates at or below 20 percent are in the Southeast and South Central regions. The list includes Texas, Louisiana, Arkansas, Alabama and Georgia.
CDC says about one-fourth of Americans have been vaccinated since October.
At first, doses were hard to come by. But as flu cases dropped, so did demand. Now there are tens of millions of unused doses. -- The CDC calculated state rates from two telephone surveys that included about 140,000 adults and nearly 75,000 children. The surveys covered vaccinations through January.
