Sweden's ambassador to the U.S. believes the country's controversial strategy of imposing only limited restrictions — and not locking down the country — is bearing success, with the capital Stockholm on course to reach herd immunity in the next few weeks.
"About 30% of people in Stockholm have reached a level of immunity," Karin Ulrika Olofsdotter told NPR. "We could reach herd immunity in the capital as early as next month."
Herd immunity means the majority of a given population has become immune to an infectious disease by either recovering from it or through vaccination. Some researchers have put the threshold for coronavirus herd immunity at 60% in some areas.
