Repeated information of benefits reduces COVID-19 vaccination hesitancy: Experimental evidence from Germany.

Our findings suggest that if soft governmental interventions such as information campaigns are employed, highlighting benefits should be given preference over debunking vaccination myths. Furthermore, it seems that repeated messages affect vaccination action while one-time messages might be insufficient, even for increasing vaccination intentions. Our study highlights the importance of testing interventions outside of survey experiments that are limited to measuring vaccination intentions-not actions-and immediate changes in attitudes and intentions-not long-term changes.
