Stage 1 Registered Report presented at the [Junior Researcher Programme Conference 2020][1]. Abstract: > This project attempts to conceptually replicate the finding that herd > immunity communication increases vaccination intentions (Betsch, C. et > al. Nat. Hum. Behav. 0056 (2017)). The effects of descriptive social > norms and the herd-immunity threshold will be additionally explored. > An online experiment will be conducted with 540 non-senior adults > residing in the UK. The social benefit of herd immunity will be > presented in both textual and animated-infographic form. The project, > submitted as a Registered Report, was granted in-principle acceptance > at the British Journal of Health Psychology. The findings will > contribute to communication strategies that harness social processes > to address vaccine hesitancy. Abstract is printed in the Conference Booklet (available upon request).
