Since 2020, the COVID-19 pandemic has had a significant impact on morbidity and mortality around the world. As one of the most successful and cost-effective health interventions for preventing infectious diseases, immunization against SARS-CoV-2, is at the moment the most effective strategy for controlling the current pandemic. Despite the high vaccine acceptance rates that countries such as Costa Rica have shown in the past, the public acceptance of the COVID-19 vaccine is still uncertain. The purpose of this study was to examine adults' willingness to get a novel COVID-19 vaccine and its potential predictors in Costa Rica. We conducted a cross-sectional study comprising a sample of 4717 adult participants living in Costa Rica who participated in a voluntary electronic survey regarding their intent to get a future COVID-19 vaccine. Results suggest that a high percentage (86.1%) of Costa Ricans aged 18 or more would be willing to be vaccinated once a safe and effective vaccine is approved and distributed in the country. Some relevant significant predictors of willingness to get a COVID-19 vaccine in Costa Rica were higher income, being male, work in the health care sector, and having a relative or a close acquaintance diagnosed with COVID-19. Our findings suggest that it is essential to concentrate efforts on the immediate development of culturally appropriate communication, dissemination, and implementation strategies to maximize immunization against SARS-CoV-2 in Costa Rica.
