The CDC's data tracker compiles data from healthcare facilities and public health authorities. It updates daily to report the total number of people in each state who have received COVID-19 boosters. The numbers reported by the CDC may vary from the numbers published on individual states' public health websites, as there may be reporting lags between the states and the CDC.
As of Jan. 25, 84,800,209 Americans had received a booster, or 40.3 percent of the country's fully vaccinated population, according to the CDC's data.
