More than 100 million Americans have received 1st COVID booster shot since August

More than 100 million Americans have received their first COVID-19 vaccine booster dose, according to data from the Centers for Disease Control and Prevention.

Boosters first became available in August 2021 for immunocompromised Americans before federal officials gradually lowered the age requirement.

Since then, nearly half of those in the U.S. who are eligible — aged 12 and older — have received their first booster as well as two-thirds of people over the age of 65. As of April 18, an average of 85,000 Americans are receiving a booster dose every day, a nearly 9% increase from the 78,000 getting their first booster dose one month ago.
