ABSTRACT
OBJECTIVE:
To analyze the number of yellow fever vaccine doses administered before and during the covid-19 pandemic in Brazil.METHODS:
This is an ecological, time series study based on data from the National Immunization Program. Differences between the median number of yellow fever vaccine doses administered in Brazil and in its regions before (from April/2019 to March/2020) and after (from April/2020 to March/2021) the implementation of social distancing measures in the country were assessed via the Mann-Whitney test. Prais-Winsten regression models were used for time series analyses.RESULTS:
We found a reduction in the median number of yellow fever vaccine doses administered in Brazil and in its regions North (-34.71%), Midwest (-21.72%), South (-63.50%), and Southeast (-34.42%) (p < 0.05). Series showed stationary behavior in Brazil and in its five regions during the covid-19 pandemic (p > 0.05). Brazilian states also showed stationary trends, except for two states which recorded an increasing trend in the number of administered yellow fever vaccine doses, namely Alagoas State (before ß = 64, p = 0.081; after ß = 897, p = 0.039), which became a yellow fever vaccine recommendation zone, and Roraima State (before ß = 68, p = 0.724; after ß = 150, p = 0.000), which intensified yellow fever vaccinations due to a yellow fever case confirmation in a Venezuelan State in 2020.CONCLUSION:
The reduced number of yellow fever vaccine doses administered during the covid-19 pandemic in Brazil may favor the reemergence of urban yellow fever cases in the country.
