Undervaccinated Kindergarteners

JAMA. 2016;316(20):2079. doi:10.1001/jama.2016.16669

The vast majority of US kindergarteners received a passing grade for being fully vaccinated on their first day of class last year. Even so, many kindergarteners are undervaccinated because they haven’t completed their immunization doses.

For the 2015-2016 school year, the CDC collected school vaccination data from all 50 states and the District of Columbia. The data showed that median vaccination coverage was 94.6% for 2 doses of measles, mumps, and rubella vaccine (MMR); 94.2% for diphtheria, tetanus, and acellular pertussis vaccine (DTaP); and 94.3% for the 2-dose varicella vaccination in the 42 states that require it. Coverage with MMR vaccine increased in 32 states last year, likely due to the 2015 measles outbreak primarily among unvaccinated children in 18 states.
