CDC experts advise Covid booster shots for over-65s and vulnerable Americans
Third dose of Pfizer vaccine would be made available to millions but doubts remain over whether it will slow pandemic
The US vaccination drive against Covid-19 stood on the verge of a major new phase as government advisers on Thursday recommended booster doses of Pfizer’s vaccine for millions of older or otherwise vulnerable Americans – despite doubts the extra shots will do much to slow the pandemic.
Advisers to the Centers for Disease Control and Prevention said boosters should be offered to people 65 and older, nursing home residents and those aged 50 to 64 who have risky underlying health problems. The extra dose would be given once they are at least six months past their last Pfizer shot.
