Abstract

Introduction: As of 2019 several different efforts have been taken to reduce the spread and combat the effects of COVID-19, the most promising being vaccination. Thus, we aimed to check the adherence and knowledge of the population about the vaccination against SARS-CoV-2/COVID-19. Methods: Cross-sectional study with online collection of sociodemographic, health, behavioral and knowledge data. Collection was conducted between July 17 and September 21, 2021, including subjects of both genders and 18 years of age or older. The sample size was calculated based on 95% confidence level, study power of 80%, ratio of unexposed/exposed of 5:5, total prevalence of the outcome of 35%, expected frequency of the outcome in unexposed of 23.3% and, PR of 2, resulting in a minimum n of 546 participants. Results: The sample was composed of 683 participants, with a predominance of female (66.0%), non-pregnant (98.0%), age 30-39 years (29.7%), white (83.7%), postgraduates (61.2%), workers (78.8%), working in a field other than health (78.1%) and health students (83.6%). The population adhesion to the vaccine was 85,8%, being observed a high knowledge of the collateral effects (52,7%) and a high sensation of protection between the vaccinated (74,4%) and relatively less among the non-vaccinated (4%) .Conclusion: there is a need to be intensified information by official agencies for better clarification of the population in order to reduce the impact of the pandemic and expand the vaccination schedule.
