Political Partisanship, Trust, and Attitudes toward COVID-19 Vaccines in Indonesia.

Context: This study examines the extent to which political partisanship-measured as support for either the incumbent candidate for Indonesia's presidency, Joko Widodo (popularly known as Jokowi), or for Jokowi's challenger, Prabowo-affects individuals' risk perception of COVID-19 and COVID-19 vaccine hesitancy and refusal as well as beliefs about the safety and efficacy of the COVID-19 vaccine.

Methods: The authors performed multinomial logistic and ordinary least squares regression analyses on a nationally representative sample of a national survey on public trust in COVID-19 vaccines and vaccinations that was conducted in December 2020.

Findings: Individuals who voted for Prabowo in the 2019 presidential election were more likely to have a lower level of willingness and a higher level of hesitancy to get the COVID-19 vaccine than those who cast their ballot for Jokowi as the Indonesian president.

Conclusions: Political partisanship does matter in shaping individuals' hesitancy or refusal to receive the COVID-19 vaccine in Indonesia. The effect of partisanship is also significant in shaping individuals' trust in the efficacy and safety of the COVID-19 vaccine, but it is not significantly associated with individuals' risk perceptions.
