To evaluate polio vaccination coverage in Brazil between the years 2012 and 2022. This is an ecological, quantitative, and cross-sectional study with a search conducted in April 2023. The collection occurred by accessing the Information System of the National Immunization Program (SI - PNI), available at the Department of Informatics of the Unified Health System (DATASUS-TABNET) of the Ministry of Health for each region according to the year and study variables between 2012 and 2022. The variables used in the study were: vaccination coverage, year and region. In the period between 2012 and 2022, the polio vaccination coverage in Brazil was 79.17%. The North region had the lowest number when compared to the other five Brazilian regions, with a quantitative average of 68.06%. In relation to the year with the highest quantitative vaccination coverage was 2012, in which the Midwest region showed a percentage of 109%, standing out in relation to the other regions. When analyzing when this decline began in the country, it is observed that the numbers fell from 2016, intensifying in 2020 and solidifying in 2022. Given the above findings, the relevance of a rising CV in the country is affirmed, since it decreases the chances of combated pathologies such as polio being reintroduced in the Brazilian territory. Furthermore, it is important to highlight the heterogeneity in relation to the index in each Brazilian region, indicating how the determinants and conditioning factors influence the health-disease process of individuals.
