One of the worst measles outbreaks in 20 years has swept the country. Once declared eradicated in the United States, more than 750 people in almost 30 states have contracted the disease since last year.
In Florida, children are required to receive certain immunizations before starting kindergarten. But in Miami-Dade County, more kindergartners enter school unvaccinated than any other county. The result is a vaccination rate that falls under what experts call “herd immunity,” the rate needed to prevent an outbreak.
In 2013, 92 percent of Miami-Dade County kindergartners enrolled in school fully immunized. Florida wants to immunize 95 percent of kindergartners. About half of all counties, including Miami-Dade, don't meet that goal.
In Manatee County, 95.8 percent of kindergartners were immunized in 2013. In Sarasota County, it was 93.7 percent.
