ABSTRACT Objective To describe the polio vaccination status in 26 state capitals, the Federal District, and 12 municipalities in Brazil, among children born between 2017 and 2018. Methods This was a population-based household survey conducted from 2020 to 2022, which assessed polio vaccination coverage in children, considering valid, administered, and timely doses by municipality. Results Data were collected from 37,801 children. Vaccination coverage for the complete valid dose schedule was 87.5% (95%CI 86.2;88.7), dropping to 79.6% (95%CI 78.1;81.0), when the booster dose was considered. The dropout rate was 4.5% for the complete schedule, and 11.7% for the first booster. There was no correlation between campaign implementation and high coverage. Conclusion Vaccination coverage for the complete valid dose schedule and the first booster did not meet the 95.0% target. Regional disparities and the association between vaccination coverage and social indicators should be taken into consideration in strategies to increase coverage.
