U.K. Prime Minister Boris Johnson on Wednesday announced a series of changes relaxing COVID-19 restrictions. In England, the use of mandatory certification that shows either vaccination or a recent negative test at major venues will end, as will the mandate that required the wearing of face masks in classrooms. The U.K. also is no longer recommending employees work at home, Johnson said. Self-isolation rules are still mandatory, though the waiting period will be reduced to five days after two negative tests.
