Objective: To date, there are no studies of COVID-19 cases and deaths in the Navajo Nation, US. The primary objective of this manuscript is to understand whether counties with a higher proportion of Navajo (Diné) population also had higher cases and deaths of COVID-19 and whether these dropped with vaccination.
Method: We undertook a cross-sectional analysis of county level data from March 16, 2020-May 11, 2021.
