ATLANTA, Aug 24: Most US kindergartners received the recommended vaccines for measles and other preventable diseases during the 2011-12 school year, but local clusters of unvaccinated children still pose a health risk, federal health officials said yesterday. More than 95 percent of kindergartners were vaccinated for diphtheria, tetanus, acellular pertussis, polio and hepatitis B, meeting federal guidelines, the Centers for Disease Control and Prevention said in a new report.
