Vaccine Coverage and Hesitancy Virology and Viral Diseases Immune responses and vaccinations

Abstract

OBJECTIVE: To analyze the temporal trend of vaccination coverage for hepatitis A, measles, mumps and rubella, and varicella in a Brazilian state from 2014 to 2020. METHODS: An ecological, time-series study that considered data from 853 municipalities in the state of Minas Gerais that compose the 14 regions of the state, these being the territorial units of analysis. Records of applied doses of hepatitis A, measles, mumps and rubella, and varicella vaccines registered in the Brazilian Immunization Information System were analyzed. Trends were estimated by Prais-Winsten regression and 95% confidence intervals of measures of variation were calculated. RESULTS: Low vaccine coverage of hepatitis A, measles, mumps and rubella, and varicella was identified. Coverages above 95% were observed only in 2015 for the vaccine against hepatitis A (98.8%) and, in 2016, for varicella (98.4%). The measles, mumps and rubella vaccine showed coverage of less than 95% in all analyzed years. Decreases of 13.6 and 4.3% between the years 2019 and 2020 were identified for the measles, mumps and rubella, and hepatitis A vaccines, respectively. There was a decreasing trend in hepatitis A vaccination coverage in the South (p=0.041), East (p=0.030), and North (p=0.045) regions; and for the measles, mumps and rubella in Jequitinhonha Valley (p=0.002), East (p=0.004), and North (p=0.024) regions. Increasing coverage was observed only for varicella in eight regions of the state. CONCLUSIONS: The data point to heterogeneity in the temporal behavior of vaccination coverage in Minas Gerais. The downward trend in some regions causes concern about the possibility of resurgence of diseases, such as measles, which until then had been controlled.
