• Abstract:

  In Brazil, the Ministry of Health has had the National Immunization Program (PNI) since 1973, created with the aim of reducing the incidence of vaccine-preventable diseases by making vaccines available. The reappearance of anti-vaccine movements has encouraged vaccine hesitancy and negatively impacted vaccine coverage, leading to outbreaks of vaccine-preventable diseases that were previously controlled. Also, with the advent of the COVID-19 pandemic, the need for social isolation also had a negative impact on vaccine campaigns. The objective of this work is to draw an overview of the vaccination coverage records of the Triple Viral Vaccine, from 1994 to August 2022, and of the COVID-19 Vaccine since its implementation, to build a parallel between both and to discuss the probable causes and repercussions of the epidemiological scenario of each one. Through an ecological analytical study, numbers of confirmed cases of each of these diseases were analyzed, as well as their respective vaccination coverage, associating the results with the reemergence of anti-vaccine movements and the pandemic context associated with COVID-19.
