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.
