The Centers for Disease Control and Prevention (CDC) announced in March 2022 that adults over 50 years old and immunocompromised individuals were eligible to receive their second COVID-19 booster.
Through July 2022, 19.9 million people ages 50 and up received a second booster. This represents about 30% of the 50 or older population in the US. About 1.3 million adults younger than 50 years old also received a second booster.
