Game Design and Behaviour Change using Vaxcards: A Collectable Card Game to Increase Vaccine Confidence

Confidence in vaccination presents a global challenge, and innovative interventions are needed to address this reluctance. This thesis presents the findings from a pragmatic randomised controlled trial (RCT) designed to ascertain whether an educational card game provided to high school students as an incentive within the context of a local government school-based vaccination programme was associated with an increase in the return of consent to vaccinate forms, vaccine hesitancy or increased confidence in vaccination.
