SUMMARY:

The epidemiological profile of the Brazilian population in 1980 was characterized by high morbidity and mortality from communicable diseases. The mission of the National Immunization Program is based on the control, eradication and elimination of vaccine-preventable diseases. Shortcomings in 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, obtained from the Department of Informatics of the Unified Health System, Ministry of Health. Vaccination coverage rates were used as the dependent variable and the population of those years as the denominator. The independent variables were Brazilian regions, years, age groups and immunobiologicals, and Excel software and the Joinpoint Regression Program were used for data analysis. The preliminary 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. The temporal analysis of the states in the North and Northeast regions showed the lowest overall average vaccination coverage rates for the period. In addition, there were four temporal variations with segments to explain the autocorrelation in the periods 2013-2016, 2016-2019 and 2019-2022, following a decreasing, increasing and decreasing order. The analysis of immunobiologicals showed a slight increase from 2013 to 2015, followed by a significant drop in 2016, maintaining a downward trend. Also noteworthy is the prevalence of some immunobiologicals, such as Bacillus Calmette-Guérin and Poliomyelitis, with coverage of over 90%, which are offered to children under one year old. On the other hand, the list for the 1 to 4 age group showed a drop, with coverage of less than 70% in some states, such as DTP, which immunizes Diphtheria, Tetanus and Pertussis. There was a variation between the states, and this shows the need for effective operational and planning action in Immunization in order to achieve coverage above 90%, strengthening the disease prevention policy in Brazil.
