Communicating doctors’ consensus persistently increases COVID-19 vaccinations | Nature

Our results shed light on the role that misperceptions of the distribution of expert views have in vaccine hesitancy, and also show how this barrier can be lifted by providing accurate information. We provide evidence that (1) the vast majority of medical doctors in the Czech Republic trust the approved COVID-19 vaccines, (2) the vast majority of respondents in a nationally representative survey substantially underestimate the percentage of doctors with positive views of the vaccine, and (3) correcting these misperceptions has lasting positive effects on vaccine uptake. Although existing experiments have made progress in identifying low-cost strategies to increase vaccination intentions4,13,14,15 and uptake5 measured shortly after the intervention, this paper integrates the experiment in longitudinal online data collection and contributes by identifying a low-cost, scalable treatment that has lasting effects on behaviour.
