In a major step toward returning to pre-pandemic life, the Centers for Disease Control and Prevention eased mask-wearing guidance for fully vaccinated people on Thursday, allowing them to stop wearing masks outdoors in crowds and in most indoor settings, AP reported. “Today is a great day for America,” President Joe Biden said during a Rose Garden address heralding the new guidance, an event where he and his staff went without masks.

Hours earlier in the Oval Office, where Biden was meeting with vaccinated Republican lawmakers, he led the group in removing their masks when the guidance was announced.

“If you are fully vaccinated, you no longer need to wear a mask,” he said, summarizing the new guidance and encouraging more Americans to roll up their sleeves. “Get vaccinated — or wear a mask until you do.”

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

The Biden administration faced pressure to ease restrictions on fully vaccinated people — those who are two weeks past their last required Covid-19 vaccine dose — in part to highlight the benefits of getting the shot. The country’s aggressive vaccination campaign has paid off: US virus cases are at their lowest rate since September, deaths are at their lowest point since last April and the test positivity rate is at the lowest point since the pandemic began.

The announcement came as many states and communities have already been lifting mask mandates amid improving virus numbers and as more Americans have been shedding face coverings after getting shots.

To date more than 154 million Americans, nearly 47% of the population, have received at least one dose of Covid-19 vaccine, and nearly 119 million are fully vaccinated. The rate of new vaccinations has slowed in recent weeks, but with the authorization Wednesday of the Pfizer shot for children ages 12 to 15, a new burst of doses is expected in the coming days.
