WASHINGTON — In a move to send the country back toward pre-pandemic life, the Centers for Disease Control and Prevention on Thursday eased indoor mask-wearing guidance for fully vaccinated people, allowing them to safely stop wearing masks inside in most places.

The new guidance still calls for wearing masks in crowded indoor settings like buses, planes, hospitals, prisons and homeless shelters but will help clear the way for reopening workplaces, schools, and other venues — even removing the need for masks or social distancing for those who are fully vaccinated.

"We have all longed for this moment — when we can get back to some sense of normalcy," said Dr. Rochelle Walensky, the director of the CDC.

The CDC will also no longer recommend that fully vaccinated people wear masks outdoors in crowds. The announcement comes as the CDC and the Biden administration have faced pressure to ease restrictions on fully vaccinated people — people who are two weeks past their last required COVID-19 vaccine dose — in part to highlight the benefits of getting the shot.

Walensky announced the new guidance on Thursday afternoon at a White House briefing, saying the long-awaited change is thanks to millions of people getting vaccinated -- and based on the latest science about how well those shots are working.

The easing guidance is likely to open the door to confusion, since there is no surefire way for businesses or others to distinguish between those fully vaccinated and those who are not.

To date about 154 million Americans, more than 46% of the population, have received at least one dose of the COVID-19 vaccines and more than 117 million are fully vaccinated. The rate of new vaccinations has slowed in recent weeks, but with the authorization Wednesday of the Pfizer vaccine for children ages 12 to 15, a new burst of doses is expected in the coming days.
