Reports of coverage against measles, rubella and mumps in minas Gerais State – Brazil

Introduction: Measles is a highly transmitted acute viral disease caused by the measles morbillivirus agent that leads to complications such as diarrhea, otitis, pneumonia and encephalitis. Brazil had outbreaks in some of the Brazilian states. Objective: Analyzing the MMR records Minas Gerais state, Brazil, contained in the Information System of the National Immunization Program (SIPNI) on the DATASUS platform. Methodology: Descriptive epidemiological study, quantitative and retrospective approach.Data have extracted from DATASUS (online base) of the Brazilian Ministry of Health. The vaccine coverage of the MMR has obtained for the 1st (D1) and the 2nd dose (D2), from 2015 to 2018. All data were analyzed with Generalized Linear Models. Results: In 2015, D1 reached the goal of 95% in almost all regions (homogeneity = 76.92%). The vaccination coverage rate was different between years (Wald Chi-square = 33.88, p< 0.001, d.f. = 3), between doses (Wald Chi-square = 219.52, p < 0.001, d.f. = 1), and was significant for interaction between year and dose (Wald Chi-square = 78.31, p < 0.001, d.f. = 3) and significant for the macro-region (Wald Chi-square = 46.56, p p< 0.001, d.f. = 12). It is observed that D1 obtained higher values than D2 in all years evaluated. In D2, none of the years analyzed obtained the mean percentage required for coverage.
