U.S. health officials say Americans fully vaccinated against COVID-19 can stop wearing masks outside
Changes comes as more than a third of U.S. adults now have both doses
In a move that may give Canadians pangs of jealousy — or hope for a post-pandemic future — U.S. health officials now say fully vaccinated Americans usually don't need to wear masks outdoors anymore.
The U.S. Centers for Disease Control and Prevention (CDC) released the updated guidance Tuesday in yet another carefully calibrated step on the road back to normal from the coronavirus outbreak that has killed over 570,000 people across the country.
For most of the past year, the CDC had been advising Americans to wear masks outdoors if they are within six feet of each other.
Now, the guidance is that fully vaccinated Americans can ditch that step unless they are in a big crowd of strangers, and those who are unvaccinated can go without a face covering outside in some cases, too.
The change comes as more than half of U.S. adults have gotten at least one dose of coronavirus vaccine, and more than a third have been fully vaccinated.
"It's the return of freedom," said Dr. Mike Saag, an infectious disease expert at the University of Alabama at Birmingham, who welcomed the change.
"It's the return of us being able to do normal activities again. We're not there yet, but we're on the exit ramp. And that's a beautiful thing."
More people need to be vaccinated, and concerns persist about variants and other possible shifts in the epidemic. But Saag said the new guidance is a sensible reward following the development and distribution of effective vaccines and about 140 million Americans stepping forward to get their shots.
The CDC, which has been cautious in its guidance during the crisis, essentially endorsed what many Americans have already been doing over the past several weeks.
CDC guidance differs for those not fully vaccinated
The CDC guidance says that fully vaccinated or not, people do not have to wear masks outdoors when they walk, bike or run alone or with members of their household. They also can go maskless in small outdoor gatherings with fully vaccinated people.
But from there, the CDC has differing guidance for people who are fully vaccinated and those who are not.
Unvaccinated people — defined by the CDC as those who have yet to receive both doses of the Pfizer or Moderna vaccine or the one-shot Johnson & Johnson formula — should wear masks at outdoor gatherings that include other unvaccinated people. They also should keep using masks at outdoor restaurants.
That advice echoes what Canadians are still being told by federal officials: "Right now, we still need to follow public health measures to reduce the spread of COVID-19 and save lives," reads a federal vaccine fact sheet.
Canada has delayed second doses of COVID-19 vaccines by up to four months — the longest interval recommended by a country so far — which means far fewer residents on this side of the border are fully vaccinated.
Close to a third of Canadians have had at least one dose, but only around three per cent are considered fully vaccinated, which is 10 times less than the U.S. rate.
But even though vaccinations are ramping up in Canada now as well, there haven't been fresh recommendations on what Canadians can or can't do while waiting for their second shot.

Freedoms may be 'motivator' for vaccination
In the U.S., fully vaccinated people do not need to cover up during most outdoor gatherings, the CDC says, though it recommends everyone should keep wearing masks at crowded outdoor events such as concerts or sporting events.
The agency continues to recommend masks at indoor public places, such as hair salons, restaurants, shopping centres, museums and movie theatres.
Dr. Babak Javid, a physician-scientist at the University of California, San Francisco, said the new CDC guidance is sensible.
"In the vast majority of outdoor scenarios, transmission risk is low," Javid said.
Javid has favoured outdoor mask-wearing requirements because he believes they increase indoor mask-wearing, but he said Americans can understand the relative risks and make good decisions.
"The key thing is to make sure people wear masks indoors" while in public spaces, he said.
He added: "I'm looking forward to mask-free existence."
"The timing is right because we now have a fair amount of data about the scenarios where transmission occurs," said Mercedes Carnethon, a professor and vice chair of preventive medicine at Northwestern University's Feinberg School of Medicine in Chicago.
What's more, she said, "the additional freedoms may serve as a motivator" for people to get vaccinated.
