Study suggests Pfizer vaccine works against virus variant
By LAURAN NEERGAARD
New research suggests Pfizer’s COVID-19 vaccine can protect against a mutation found in the two more-contagious variants of the coronavirus that have erupted in Britain and South Africa.
The study was preliminary and did not look at the two other major vaccines being used in the West — Moderna’s and AstraZeneca’s. But it was reassuring, given questions of whether the virus could mutate to defeat the shots on which the world has pinned its hopes.
“There’s no reason to think the vaccines won’t work just as well on these strains,” said Dr. Frederic Bushman of the University of Pennsylvania, who tracks how the virus mutates.
