The US Centers for Disease Control and Prevention (CDC) says fully vaccinated Americans do not need to wear a mask when outdoors.
Those who have received all the necessary strokes can close their face if they are alone or in small groups of vaccinated people, the new guideline says.
But the CDC left its lead in throwing masks inside crowded places or places.
So far, more than 95 million Americans have been fully vaccinated.
Following the CDC announcement on Tuesday, President Biden described the new leadership as “extraordinary progress.”
“Our scientists are convinced by the data that the chances of getting the virus or passing it on to others are very, very low,” Biden said. “The conclusion is clear. “If you have been vaccinated, you can do more.”
The president also called on Americans who have not yet received their shots to do so, calling it a “patriotic” operation.
“Vaccines are about saving your life as well as the lives of the people around you, but they also help us get closer to a more normal life.”
Health officials presented the new safety guidelines at a briefing at the White House Coronavirus Working Group on Tuesday.
“Small, medium-sized gatherings for people who are vaccinated outdoors can be safely performed without a mask,” said Dr. Rochelle Valensky, CDC Director. This includes exercising or eating out.
He said the decision to wear a mask to larger outdoor gatherings would depend on other concerns, such as how well the venue is ventilated, “how much space is left between people”.
The guidelines apply to all vaccinated people, which means two weeks after the final shot of the vaccine.
Evidence suggests that while Covid-19 infections may occur outdoors, the risks of transmission are very low. Early studies show that people who are fully vaccinated are much less likely to spread the virus.
Dr. Valensky says that full mask vaccinations are designed primarily to “protect the unvaccinated.”
“We really want unvaccinated people to limit their interactions with people, to return to the basic principles of increased ventilation and distance,” he said.
Health officials said the number of cases in the United States was stabilizing as vaccine rates continued to rise, and on Tuesday called on more people to register for vaccinations.
Nearly 141 million Americans, 42% of the total population, received at least one dose of the vaccine as of April 26, according to the CDC.
