After warning that the U.K. had "tough, tough weeks to come," British Prime Minister Boris Johnson on Monday announced a national lockdown for England to help contain a new, highly contagious variant of Covid-19. Scotland's leader, Nicola Sturgeon, also announced a new stay-at-home order for the country's citizens starting at midnight. The U.K. began its rollout of the Oxford-AstraZeneca vaccine on Monday, after starting to deploy the Pfizer-BioNTech shot in December. To protect as much of its population as possible, the U.K. government has decided to implement a 12-week delay between the first and second doses of both the Pfizer-BioNTech and Oxford-AstraZeneca vaccines. The delay was criticized by the British Medical Association.
