SUMMARY:

The mission of the National Immunization Program is based on the control and eradication of vaccine-preventable diseases. Insufficient campaigns and declining vaccination coverage can increase the burden of endemic infectious diseases and the risk of resurgence of eliminated pathogens. In view of this, this study aims to assess vaccination coverage in Brazil, based on the time series from 2000 to 2022. This is a national population-based ecological study, using secondary data obtained from the Department of Informatics of the Unified Health System of the Ministry of Health, collected from February to May 2023. The dependent variables used were vaccination coverage and immunobiologicals, and the independent variables were Brazilian regions, states, years and underage age group. The data was analyzed using Excel 2016 for Windows, Joinpoint Regression Program and Power Business Intelligence. The results obtained in this study point to overall vaccination coverage of the Brazilian population above 80% in 2001, 2004, 2011, 2014 and 2015 and a considerable decline from 2016 onwards, with the lowest rates recorded in 2016 and 2021. In the temporal analysis, the states of the North, Northeast and Southeast had the lowest overall average vaccination coverage rates for the period. In addition, the linear regression showed four temporal variations with straight line segments to explain the autocorrelation, showing equivalent breakpoints in the 2013-2016, 2016-2019 and 2019-2022 periods, following a decreasing, increasing and decreasing order. The Northern region shows a negative variation with statistical significance in the 2019-2022 segment, confirming the downward trend. As for immunobiologicals in children under two years of age, the BCG vaccine leads the highest rates in the Brazilian states, reaching parameters above expectations (90%). In the state of Espírito Santo, the rates developed by the polio vaccine surpass BCG, and in all the country's states the target against polio (95%) is reached, except in Amapá. Another immunobiological that performs well is dose one of the triple viral vaccine, with the states of Amazonas, Amapá and Acre failing to reach the target (95%). In the regions of Brazil, high rates of vaccination coverage were identified in 2015 in the Northeast, especially in the states of Ceará and Pernambuco. The same behavior in 2015 can be seen in the North, with emphasis on the state of Rondônia, in the Midwest with the state of Minas Gerais and in the South with visibility in the state of Santa Catarina. In the Southeast of the country, high vaccination rates are not identified in a specific year, so it can be seen that the Federal District leads the rates in the period from 2004 to 2010, followed by a downward trend in subsequent years, and the state of Mato Grosso do Sul recorded high vaccination rates in 2014 and 2015. The importance of the strategy of systematic updating of health professionals, training in information systems, as well as the microplanning of high-quality vaccination activities of the routine program, intensification and campaigns is essential for all stages of vaccination to be carried out properly and safely, reaching as many people as possible.
