Abstract

The scope of this article is to analyze vaccination coverage rates in children under one year of age during the period from 2015 to 2020 in the state of Minas Gerais (MG). It involved an ecological, time-series study on vaccination coverage in children under 1 year of age, considering the 28 Regional Health Management/Superintendencies (GRS/SRS) of MG as the unit of analysis. The following immunobiological vaccine coverage was analyzed: Bacillus Calmette and Guérin, human rotavirus, pneumococcal 10, pentavalent, meningococcus C, yellow fever, and polio vaccines. The Prais-Winsten autoregressive model was employed for trend analysis. The year 2020 stands out, as it presented the lowest proportion of GRS and SRS that reached the recommended vaccine coverage goals for the immunobiologicals analyzed. Regarding the analysis of the coverage trend, 8 of the 28 GRS/SRS showed a decreasing trend for at least 5 of the 7 immunobiologicals evaluated. We observed a downward trend in the vaccination coverage of at least five immunobiologicals in eight of the GRS/SRS, with emphasis on the Pentavalent vaccine, which showed a downward trend in vaccination coverage in 60.71% of the GRS and SRS.

O objetivo deste artigo é analisar as taxas de coberturas vacinais em crianças menores de um ano durante o período de 2015 a 2020 no estado de Minas Gerais (MG). Estudo ecológico, de série temporal, sobre as coberturas vacinais em crianças menores de 1 ano, considerando-se como unidade de análise as 28 Gerências/Superintendências Regionais de Saúde (GRS/SRS) de MG. Analisaram-se as coberturas vacinais dos seguintes imunobiológicos vacinas: contra o Bacilo de Calmette e Guérin (BCG), contra rotavírus humano, contra pneumococo 10, pentavalente, contra meningococo C, contra febre amarela e contra a poliomielite. Empregou-se o modelo autorregressivo de Prais-Winsten para análise de tendência. Destaca-se o ano de 2020, que apresentou a menor proporção de GRS e SRS que alcançaram as metas preconizadas de cobertura vacinal para os imunobiológicos analisados. Quanto à análise de tendência da cobertura, 8 das 28 GRS/SRS apresentaram tendência decrescente de, pelo menos, 5 dos 7 imunobiológicos avaliados. Observou-se tendência decrescente na cobertura vacinal de pelo menos cinco imunobiológicos em oito das GRS /SRS, com destaque para a vacina Pentavalente, que apresentou tendência decrescente de cobertura vacinal em 60,71% das GRS e SRS.
