As of this week, federal data from the Centers for Disease Control and Prevention (CDC) show that 74.4% of the total population in the United States have received at least one dose of a COVID-19 vaccine. While vaccination coverage has increased, it remains uneven across the country. Amid the current Omicron variant-related surge, unvaccinated people are at particularly increased risk for infection, severe illness, and death. As of January 10, 2022, White people accounted for the largest share (65%) of people who are unvaccinated.1 Over the course of the vaccination rollout, Black and Hispanic people have been less likely than their White counterparts to receive a vaccine, but these disparities have narrowed over time, particularly for Hispanic people. With booster shot eligibility expanded to all individuals ages 12 and older and children ages 5-11 eligible for vaccination, ensuring equity in the uptake of booster shots and vaccinations among children is also important. However, to date, limited data are available to examine disparities among booster shot recipients and children.
