Surveys will assess parental hesitancy, parental trust in provider, and other covariates such as perceived social norms, other sources of information about vaccines, and demographic information.

  Change from Baseline in Parental Hesitancy at 6 months

Secondary Outcomes (1)

• Physician Self Efficacy Measure

  Change from Baseline in Physician Attitudes at 6 months
