Conclusion
Coverage was identified as being below recommended levels for most vaccines. Disinformation should be combated in order to avoid vaccination hesitancy. There is a pressing need to recover coverages, considering public health service access and socioeconomic disparities. Main results: Vaccination coverage of children up to 4 years old was 50.2% in Belo Horizonte, and 64.9% in Sete Lagoas. Fear of severe reactions and believing that vaccination against eradicated diseases is unnecessary were the main reasons for vaccination hesitancy. Implications for services: Recovery of high vaccination coverage among children, considering public health service access conditions and socioeconomic inequities. Acting on reasons for hesitancy that can assist in targeting actions. Perspectives: The multifactorial context of vaccination hesitancy demands the development of health education strategies to raise awareness about child immunization. Objetivo: Descrever as coberturas e vacilación de las vacunas del calendario básico infantil en Belo Horizonte y Sete Lagoas, Minas Gerais. Métodos: Inquéritos epidemiológicos de base poblacional realizados, de 2020 a 2022, para estimar coberturas vacunales por tipo de imunobiológico y esquema completo (dosis válidas y aplicadas) segundos estratos socioeconómicos, y los motivos de vacilación vacunal. Resultados: A cobertura vacunale global con dosis válidas e a vacilación vacunal de pelo menos uma vacuna foram, respectivamente, de 50,2% (IC95% 44,1;56,2) e 1,6% (IC95% 0,9; 2,7), en Belo Horizonte (n = 1.866), e de 64,9% (IC95% 56,9;72,1) y 1,0% (IC95% 0,3;2,8), en Sete Lagoas (n = 451), con diferencias entre los estratos. O medo de reações graves foi o principal motivo de vacilación. Conclusión: Identificou-se cobertura vacunale abaixo do preconizado para a mayoria das vacunas. La desinformación debe ser combatida, evitando la vacilación vacunal. Há necessidad de recuperar la cobertura vacunale, considerando el acesso y las disparidades socioeconómicas.
Methods
Population-based epidemiological surveys performed from 2020 to 2022, which estimated vaccine coverage by type of immunobiological product and full schedule (valid and ministered doses), according to socioeconomic strata; and reasons for vaccination hesitancy.
Objective
To describe vaccination coverage and hesitation for the basic children's schedule in Belo Horizonte and Sete Lagoas, Minas Gerais state, Brazil.
Results
Overall coverage with valid doses and vaccination hesitancy for at least one vaccine were, respectively, 50.2% (95%CI 44.1;56.2) and 1.6% (95%CI 0.9;2.7), in Belo Horizonte (n = 1,866), and 64.9% (95%CI 56.9;72.1) and 1.0% (95%CI 0.3;2.8), in Sete Lagoas (n = 451), with differences between socioeconomic strata. Fear of severe reactions was the main reason for vaccination hesitancy.
