The United States Centers for Disease Control and Prevention (CDC) reported that most kindergartners in the United States received their recommended vaccines for measles and other diseases during the 2012-2013 school year. However, the CDC also mentioned concern about unvaccinated clusters of children that are at risk from vaccine preventable diseases, and may pose a health risk to the community at large.
Overall, 48 states and DC (as well as 8 US jurisdictions, including Guam, Puerto Rico and other territories) reported 2012-13 school vaccination coverage. Approximately 94.5% of kindergartners had received their complete MMR vaccinations, an insignificant drop from the 2011-12 level of 94.8%. DTaP coverage was 95.1%, above Healthy People 2020 target of 95%. For the varicella vaccine, 93.8% of American kindergartners received both necessary doses.
