New research suggests that 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.
The mutated version spreading in Britain has also been detected in the U.S. and numerous other countries.

Pfizer study suggests vaccine works against coronavirus variant
New research suggests that Pfizerâs COVID-19 vaccine can protect against a mutation found in two highly contagious variants of the coronavirus that erupted in Britain and South Africa. Those variants are causing global concern. They both share a common mutation called N501Y, a slight alteration on one spot of the spike protein that coats the virus. That change is believed to be the reason they can spread so easily.
Most of the vaccines being rolled out around the world train the body to recognize that spike protein and fight it. Pfizer teamed with researchers from the University of Texas Medical Branch in Galveston for laboratory tests to see if the mutation affected its vaccineâs ability to do so.
