The Centers for Disease Control and Prevention (CDC) reports that vaccine coverage for children entering kindergarten for the 2012-2013 school year was at or near the national Healthy People 2020 targets of 95 percent for two doses of MMR vaccine, four doses of DTaP, and two doses of varicella vaccine. However, the CDC researchers noted that low vaccination and high exemption levels can form within communities and raise the risk for disease. Each year, the CDC analyzes school vaccination coverage data from federally funded immunization programs as well as exemption rates. Among 48 states and the District of Columbia, vaccination coverage averaged 94.5 percent for two doses of MMR, 95.1 percent for local requirements for DTaP, and 93.8 percent for two doses of varicella vaccine. Among 49 states and the District, exemption rates had a median total of 1.8 percent. Kindergartners were considered up-to-date on each vaccine if they met all of the doses required for school entry in their jurisdiction. Exemptions included medical exemptions, religious exemptions, or philosophic exemptions.
