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

November 6, 2017

This three-arm, randomized controlled trial investigated if a Web-based, social media intervention increases early childhood immunization and was conducted in Colorado from September 2013 to July 2016. Participants were pregnant women, randomly assigned (3:2:1) to a website with vaccine information and interactive social media components, a website with vaccine information, or provided standard-of-care. Vaccination was assessed in infants of participants from birth to age 200 days to determine the rates of undervaccination. Findings report that during pregnancy, exposure to web-based vaccination information with social media applications can positively influence parental vaccine behaviors. As a complement to routine well-child care, the information appears to be effective when presented to parents before their children are born.
