-----------------
The primary aim of this trial is to test the effectiveness of an intervention to train primary care physicians to determine if it leads to decreased parental vaccine hesitancy.

Detailed Description

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Parental Vaccine Hesitancy Measure | The investigators will contact mothers of newborns in study practices and conduct a telephone survey at two time points: baseline and 6 months. 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 Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Physician Self Efficacy Measure | Assessed via self-administered surveys of providers in all participating clinics at baseline and 6-months. The investigators will measure physician attitudes, perceived norms, intentions to change behavior, practice characteristics, and physician demographics. | Change from Baseline in Physician Attitudes at 6 months |
