[Vaccines in Brazil in the pandemic: a study of public perception]

In a polarized and complex context, the COVID-19 pandemic has highlighted, vaccine hesitancy as one of several crises. Studies indicate a high intention to vaccinate in Brazil, but official data indicate insufficient vaccination coverage. In order to identify the perception and attitudes of Brazilians, an empirical study was carried out using the survey technique, totaling 2,069 household interviews with people aged 16 and over in urban centers from August to October 2022. To analyze the results, multivariate statistical techniques, factor analysis and regression models, were used. In general, respondents expressed a positive view of vaccines, but the survey results suggest that confidence in vaccines may be shaken. The level of education and scientific knowledge affect some of the attitudes of Brazilians towards vaccines. Indices were constructed considering values, trajectories, life context and habits of the interviewees. In addition to the region of residence and religion, gender parity indices, vision of the role of the State and trust in science provided relevant information, indicating the need for aligned communication strategies with different audiences considering the variables that impact the perception of vaccines.
