COVID-19 Vaccination and Racial/Ethnic Inequities in Mortality at Midlife in Minnesota

Abstract

Recent research underscores the exceptionally young age distribution of COVID-19 deaths in the U.S. compared with that of international peers. This paper characterizes how high levels of COVID-19 mortality at midlife ages (45-64 years) are deeply intertwined with continuing racial inequity in COVID-19 mortality. Mortality data from Minnesota in 2020-2022 were analyzed in June 2022. Death certificate data (COVID-19 deaths N=12,771) and published vaccination rates in Minnesota allow vaccination and mortality rates to be observed with greater age and temporal precision than national data. Black, Hispanic, and Asian adults aged <65 years were all more highly vaccinated than White populations of the same ages during most of Minnesota's substantial and sustained Delta surge and all the subsequent Omicron surges. However, White mortality rates were lower than those of all other groups. These disparities were extreme; at midlife ages (ages 45-64 years), during the Omicron period, more highly vaccinated populations had COVID-19 mortality that was 164% (Asian-American), 115% (Hispanic), or 208% (Black) of White COVID-19 mortality at these ages. In Black, Indigenous, and People of Color populations as a whole, COVID-19 mortality at ages 55-64 years was greater than White mortality at 10 years older. This discrepancy between vaccination and mortality patterning by race/ethnicity suggests that if the current period is a pandemic of the unvaccinated, it also remains a pandemic of the disadvantaged in ways that can decouple from vaccination rates. This result implies an urgent need to center health equity in the development of COVID-19 policy measures.
