[Childhood vaccine hesitancy and COVID-19: an analysis based on the perception of health professionals].

This article presents the results of a study on health professionals' perceptions of childhood vaccine hesitancy related to COVID-19. Based on the theoretical construct of vaccine hesitancy, a qualitative study was conducted with 86 primary health care (PHC) workers in four municipalities in four Brazilian states and in the Federal District. A thematic analysis was performed and three categories were obtained: fear, misinformation about vaccines, and the role of health professionals. Fear as a reason for vaccine hesitancy has led to reflections on the Brazilian Federal Government's management of the pandemic, especially regarding governability and the consequences of the use of digital platforms on the population. Fear was related to the vaccine still being perceived as experimental; to the adverse reactions it may cause; to the lack of long-term studies; to the false perception of reduced risk of COVID-19 in children; and to the Federal Government's behavior, which creates uncertainty about the effects of the vaccine. Vaccine misinformation was related to fake news about the vaccine and its reactions; the phenomenon of infodemic and misinformation; and the lack of guidance and knowledge about vaccines. Finally, the article discusses the fundamental role of PHC workers in increasing vaccination coverage due to the trust among the population and proximity to the territories, factors that enable the reversal of fear and misinformation about vaccines. Throughout the study, authors' sought to show the convergences between the content of the themes outlined and the determinants of vaccine hesitancy and to consider possibilities for rebuilding high adherence to childhood vaccines.
