- Abstract
The re-emergence of vaccine-preventable diseases due to the decline in vaccine coverage (VC) has been documented in several countries. The objective was to analyze the VC, the homogeneity of VC, and measles cases in Brazil from 2011 to 2021, focusing on the period of the COVID-19 pandemic, its temporal trend, spacetime distribution, and factors associated with clusters of lower VC. This is an ecological study on measles VC (dose 1), with methods of interrupted time series and evaluation of spatio-temporal disposition, through the sweep test to identify clusters of VC. Starting in 2015, we observe a progressive decline in VC and homogeneity, with an accentuation after 2020, in all regions, particularly in the North and Northeast. Low VC clusters were associated with worse human development indicators, social inequality, and less access to the Family Health Strategy. In Brazil, the pandemic intensified health inequalities with low VC of measles in socially more vulnerable and unequal municipalities. There is a risk of virus circulation, however, the challenge of strengthening primary care, improving health communication and guaranteeing access to the vaccine, reducing missed opportunities for vaccination and vaccine hesitancy, is highlighted.
