Fewer people are getting vaccine booster shots in the U.S. as the Omicron Covid-19 surge fades and more Americans return to normal patterns of life, federal data show.
The seven-day average for booster shots administered daily was about 149,000 on Feb. 19, down from a little more than a million in early December, when authorities expanded access and Omicron was first detected in the U.S., the Centers for Disease Control and Prevention estimates.
