The primary goal of this project is to evaluate the effectiveness of an innovative intervention designed to address these barriers—the Screening for Hesitancy to Optimize Talk (SHOT) intervention—in improving provider-parent vaccine discussions and increasing vaccine acceptance. The SHOT intervention involves administering a validated parent-report measure to parents and communicating their score and item-specific responses to their child's provider before their child's 2 and 6 month health supervision visits. The survey contains 15 questions regarding Health Belief Model concepts that influence parent vaccination behavior and has been shown to predict under-immunization.
