U.S. regulators gave early indications they may grant emergency-use authorization to Pfizer Inc.’s vaccine, calling the shot highly effective with no safety issues. The news came on a day when the number of infections in the U.S. topped 15 million.
Britain became the first country to start administering the vaccine to its population, kicking off the western world’s Covid immunization campaign. Prime Minister Boris Johnson warned people to keep their “discipline” during the rollout, noting that cases are starting to rise in London. Germany plans to vaccinate as many as 8 million people in the first quarter of 2021.
