Fully vaccinated Americans need not wear masks outdoors unless in big crowd, says US CDC

With more than half of US adults having received at least one dose of the Covid-19 vaccine, the CDC says vaccinated Americans need not wear masks unless they are in a big crowd of strangers.

The Centers for Disease Control and Prevention eased its guidelines Tuesday on the wearing of masks outdoors, saying fully vaccinated Americans don’t need to cover their faces anymore unless they are in a big crowd of strangers. And those who are unvaccinated can go outside without masks in some situations, too. The new guidance represents another carefully calibrated step on the road back to normal from the coronavirus outbreak that has killed over 570,000 people in US.
