Web-based Social Media Intervention to Increase Vaccine Acceptance: A Randomized Controlled Trial

Interventions to address vaccine hesitancy and increase vaccine acceptance are needed. This study sought to determine if a web-based, social media intervention increases early childhood immunization. The results demonstrate that web-based vaccine information with social media technologies can positively influence parental vaccine decisions. As a complement to routine well-child care, the information appears to be effective when presented to parents before their children are born.
