Uma análise comparativa das coberturas vacinais da tríplice viral e poliomielite nas regiões brasileira

Abstract

INTRODUCTION: Vaccines contain in their base inactive virus, proteins, polysaccharides and attenuated microbial agents. For the control, programming, coordination and monitoring of vaccines, Brazil has the National Immunization Program (PNI). The introduction of the vaccine was difficult due to the poor acceptance of the population, due to the lack of knowledge of the great importance of the drug and also for cultural reasons, leading society to organize the “Vaccine Revolt”. Years later, days of vaccination campaigns were created, the so-called “D” days. OBJECTIVES: To analyze vaccine coverage in Brazilian regions of MMR and polio vaccines between the years 2013 to 2020. In terms of vaccination coverage for

poliomyelitis and MMR, we can see that the North region is the region with the lowest number of vaccination coverage, thus adding up every year. METHODOLOGY: This is a descriptive study with secondary data, the target audience of the study are children under five years of age, aiming to avoid a recrudescence of the diseases, and the data were extracted from the database of the Ministry of Health, Datasus. The data were analyzed using excel for tabulation and presentation of the results, it was produced in the form of graphs. RESULTS: There was a significant drop in vaccine coverage in the period evaluated, with the North region being the most affected. CONCLUSION: It is believed that the reasons that contributed to the reductions in vaccination coverage were due to the lower demand for vaccination services, the population's lack of knowledge about the importance of immunologicals, or even the moving of children to other municipalities, and the distance from home with the health service.
