ABSTRACT
OBJECTIVE: To analyze vaccination coverage and factors associated with incomplete vaccination in inland municipalities of Northeastern Brazil.
METHODS: This was a household survey using cluster sampling conducted in Vitória da Conquista, Bahia state, Caruaru, Pernambuco state, Sobral, Ceará state and Imperatriz, Maranhão state between 2020 and 2022. Vaccination coverage by valid doses and vaccine hesitancy were analyzed, with the odds ratio (OR) estimated and adjusted using logistic regression.
RESULTS: Among 1,847 children, complete vaccination coverage was 49.2% (95%CI 43.9;54.5). Factors associated with incomplete vaccination included: higher income (OR 1.53; 95%CI 1.02;2.31), residence in Sobral (OR 4.35; 95%CI 3.04; 6.21) and >1 child (OR 1.20; 95%CI 1.11;1.32). Parental decision not to vaccinate and difficulties in traveling to vaccination centers contributed to vaccine hesitancy.
CONCLUSION: Low vaccination coverage and incomplete vaccination were associated with social issues in the socioeconomic strata analyzed.
