Most Canadians who have been vaccinated are told they'll have to wait for four months to receive the booster. The idea is that'll hold you in the meantime. A UK study finds this single-dose regime may leave Canadians vulnerable , not so much to Covid Classic, but to the steadily emerging Covid variants. And that's for the Cadillac of vaccines, Pfizer's.
