Abstract:

Vaccinating against COVID-19 is the main hope to end the current pandemic. We develop and test experimentally three phone-based cumulative interventions to increase COVID-19 vaccine acceptance in Mozambique. First, the provision of a simple positive message informing about these vaccines. Second, the activation of social memory on the country’s success in eradicating wild polio. Finally, the inoculation against fake news by developing among participants a critical view towards misleading information. We find that the combination of the three interventions increases COVID-19 vaccine acceptance and trust in institutions.
