More than a month after federal officials recommended a new version of the COVID-19 vaccines, 7% of U.S. adults and 2% of children have gotten a shot.

A month after federal officials recommended new versions of COVID-19 vaccines, 7% of U.S. adults and 2% of children have gotten a shot.

One expert called the rates “abysmal.”

The numbers, presented Thursday at a meeting held by the Centers for Disease Control and Prevention, come from a national survey of thousands of Americans, conducted two weeks ago.

The data also indicated that nearly 40% of adults said they probably or definitely will not get the shot. A similar percentage of parents said they did not plan to vaccinate their children.
