Fully vaccinated people are exhaling this weekend, ditching masks and easing up on social distancing, per the latest Covid-19 guidance put out by the Centers for Disease Control and Prevention. The new advice marks a significant milestone in the nation’s effort to stamp out the disease, and signals the beginning of a return to normalcy. But scientists say there are good reasons not to toss out your mask stash just yet.
“It’s important to not see this change as a signal that this means that the pandemic is over or that there is no capacity for policy reversals in the future,” said William Hanage, an epidemiologist at Harvard’s T.H. Chan School of Public Health.
