Sponsor's own description

Vaccination hesitancy is identified as a threat to global health by the World Health Organization (WHO). For adolescents undergoing vaccination at school, prior studies demonstrate that concerns about pain and/or fear of needles contribute to negative experiences with vaccination and non-compliance with vaccination. The investigators developed an intervention that addresses vaccination hesitancy. In this study, investigators will evaluate the effectiveness of this intervention in a randomized controlled trial.
