England Unveils Winter Covid Strategy

Prime Minister Boris Johnson of Britain announced a plan on Tuesday to offer all those age 50 and older a booster vaccine as part of a winter coronavirus strategy — plunging Britain into a growing debate over whether lower-income countries should get shots first. The prime minister is taking the step to try to prevent a new surge in cases from overwhelming the National Health Service, and to avoid another lockdown in a country wearied by the pandemic and earlier measures that included some of the strictest restrictions in the world.
