Identifying early adopters of COVID-19 vaccines in Latin America

COVID-19 vaccine hesitancy is currently-one of the main obstacles to worldwide herd immunity and socioeconomic recovery. Because vaccine coverage can vary between and within countries, it is important to identify sources of variation so that policies can be tailored to different population groups. In this paper, we analyze the results from a survey designed and implemented in order to identify early adopters and laggers in six big cities located in Argentina, Colombia, Chile, Ecuador, Peru, and Dominican Republic. We find that trust in government and science, accurate knowledge about the value of vaccination and vaccine effects, and perceived risk of getting sick is associated with a higher probability to get vaccinated. We also identify potential laggers such as women and populations with high education but low knowledge about vaccines. We discuss specific strategies to promote vaccination among these populations groups as well as more general strategies designed to gain trust. These findings are specific to the context of Latin America insofar as the underlying factors associated with the choice to be vaccinated vary significantly by location and in relation to individual-level factors.
