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.

2017年和2018年巴西城市活产队列脊髓灰质炎疫苗接种状况分析：一项全国疫苗接种覆盖率调查

目的：描述巴西26个州首府、联邦区和12个直辖市2017年至2018年出生儿童的脊髓灰质炎疫苗接种状况。方法：这是一项基于人口的家庭调查，于2020年至2022年进行，评估儿童脊髓灰质炎疫苗接种覆盖率，考虑市政当局的有效、管理和及时剂量。结果：收集了37,801名儿童的数据。完整有效剂量表的疫苗接种率为87.5% (95%CI 86.2;88.7)，当考虑加强剂量时，接种率降至79.6% （95%CI 78.1;81.0）。在整个计划中，退出率为4.5%，第一次加强剂的退出率为11.7%。活动执行与高覆盖率之间没有相关性。结论：完整有效剂量计划和第一次加强疫苗接种覆盖率未达到95.0%的目标。在提高覆盖率的战略中应考虑到区域差异以及疫苗接种覆盖率与社会指标之间的关系。
