Description
Summary:ABSTRACT Objective To estimate prevalence of the full vaccination schedule for children 12 to 24 months old and to analyze associated factors. Methods Survey with cluster sampling carried out in Vitória, Espírito Santo, Brazil, between December 16, 2020, and January 4, 2021. Children born in Vitória in 2017 and 2018 were included. We estimated the prevalence of vaccination schedules. Poisson regression was used to verify association with full vaccination coverage. Results We included 788 children. Full vaccination coverage was found to be 57% taking a 95% confidence interval (95%CI 50.98;62.98). Prevalence of full vaccination coverage was lowest when private services were used for immunization (prevalence ratio [PR] 0.67; 95%CI 0.51;0.86) and when mothers had ≥ 4 children (PR 0.55; 95%CI 0.32;0.94). Conclusion We found low vaccination coverage and a drop in booster doses. Use of private services for immunization and number of children were associated with incomplete vaccination coverage.
