The US drugmaker Pfizer Inc. urged a change in policy to single dosing of its covid vaccine, saying that the new data shows one dose is 93% effective after two weeks, almost as good as two doses, according to New England Journal of Medicine letters.
Meanwhile, Moderna Inc. said that the vaccine is good against all variants except probably the South African variant.
