We analyzed the time trends and spatial distribution of MMR vaccine coverage in Brazil during 2007-2017. In early 2018, a measles outbreak started in the North region of Brazil, reaching 11 of the 27 federal units by January 24, 2019. In this period, 10,302 cases were confirmed. Although the reintroduction of measles in Brazil is likely due to migration from Venezuela, the spread of the virus was made possible by the low levels of MMR coverage, as a result of significant decreases during the study period. Areas with high concentration of municipalities with low coverage are more susceptible to the spread of the virus, especially in the North and Northeast regions. Increasing vaccination coverage is essential to block the ongoing outbreak in Brazil. Vaccination strategies might target priority areas, especially those with a marked decrease in coverage. Moreover, it is essential to extend actions to travelers, migrants and refugees.
