Abstract
ABSTRACTOBJECTIVE:To investigate how sociodemographic conditions, political factors, organizational confidence, and non-pharmaceutical interventions compliance affect the COVID-19 vaccine hesitancy in Brazil.METHODS:Data collection took place between November 25th, 2020 and January 11th, 2021 using a nationwide online survey. Subsequently, the researches performed a descriptive analysis on the main variables and used logistic regression models to investigate the factors associated with COVID-19 vaccine hesitancy.RESULTS:Less concern over vaccine side effects could improve the willingness to be vaccinated (probability changed by 7.7 pp; p < 0.10). The current vaccine distrust espoused by the Brazilian president is associated with vaccine hesitancy, among his voter base. Lower performance perception (“Very Bad” with 10.7 pp; p < 0.01) or higher political opposition (left-oriented) regarding the current presidency is associated with the willingness to be vaccinated. Higher compliance with non-pharmaceutical interventions (NPIs) is usually positively associated with the willingness to take the COVID-19 vaccine (+1 score to NPI compliance index is associated with higher willingness to be vaccinated by 1.4 pp, p < 0.05).CONCLUSION:Willingness to be vaccinated is strongly associated with political leaning, perceived federal government performance, vaccine side effects, and compliance with non-pharmaceutical interventions (NPIs).
Highlights
By July 2021, the COVID-19 pandemic had already resulted in more than 186 million cases and 4 million deaths worldwide, with Brazil ranking third place in the number of cases and second in the number of deaths[1]
In a global effort to contain the spread of the new virus, countries adopted several non-pharmacological interventions (NPI) such as social distancing[2,3,4] and face mask use[5]
This study investigates the factors associated with COVID-19 vaccine hesitancy in Brazil
Summary
By July 2021, the COVID-19 pandemic had already resulted in more than 186 million cases and 4 million deaths worldwide, with Brazil ranking third place in the number of cases and second in the number of deaths[1]. After the extraordinary efforts made to rapidly research and develop effective COVID-19 vaccines and their recent rollout, researchers and the media have pointed to a growing concern regarding public confidence in the vaccination process. “anti-vaccine movements” can foster vaccine hesitancy, reducing the population’s willingness to be vaccinated[6,7,8,9,10,11,12,13]. Several surveys have been used to characterize behaviours concerning vaccine hesitancy and NPI compliance[10,11,12,13,14,15,16,17,18]. According to the existing literature, sociodemographic conditions (e.g., education, age, or job occupation)[10,18,19,20] and political and organizational trust aspects[5,8,9,10,12,13], can affect people’s willingness to be vaccinated
