Objectives:
to investigate the factors influencing vaccine hesitancy against COVID-19 among Brazilians.
Methods:
this research employed an observational and analytical approach, utilizing a web-based survey. Data collection took place in 2020, and data analysis was conducted using structural equation modeling.
Results:
the prevalence of vaccine hesitancy was found to be 27.5% (1182 individuals). There is a negative correlation between belief in conspiracy theories and social influence. Among the various beliefs associated with vaccination intentions, only conspiracy beliefs exhibited significant predictive value. Thus, the findings suggest that personal beliefs significantly impact hesitancy towards vaccination, and also indicate that trust in governmental bodies is inversely related to hesitancy.
Conclusions:
vaccine hesitancy emerges as a multifaceted phenomenon influenced by a complex array of factors, including personal beliefs, trust in governmental bodies, and healthcare systems.
