Tracking Changes in Vaccine Attitudes and Decisions: Results from 2008 and 2016 Parental Surveys.

To monitor parental vaccine attitudes, a survey was conducted in 2008 and in 2016. In both years (90%-89%) reported full immunization of their children, and a stable majority (71%-66%) supported documentation of vaccination before entering kindergarten. However, a declining confidence in official recommendations from 87% to 72% (P < 0.0001) in 2008 and 2016, respectively, was documented, requiring effort to rebuild it.
