COVID-19 booster drive is faltering in the US

NEW YORK (AP) — The COVID-19 booster drive in the U.S. is losing steam, worrying health experts who have pleaded with Americans to get an extra shot to shore up their protection against the highly contagious omicron variant.

Just 40% of fully vaccinated Americans have received a booster dose, according to the Centers for Disease Control and Prevention. And the average number of booster shots dispensed per day in the U.S. has plummeted from a peak of 1 million in early December to about 490,000 as of last week.

Vaccination numbers are stagnant in states such as Wyoming, Idaho, Mississippi and Alabama, which have been hovering below 50%.

In Wyoming, 44% are fully vaccinated, up just slightly from 41% in September. To boost numbers, the state has been running TV ads with health care workers giving grim accounts of unvaccinated people struggling with COVID-19.

“Certainly we would like to see higher rates. But it would be wrong for anyone to think that the rates we have are due to lack of effort," Wyoming Health Department spokeswoman Kim Deti said Tuesday.
