Pfizer study suggests vaccine works against virus variant January 07, 2021 at 08:06PM

New research suggests that Pfizer's COVID-19 vaccine can protect against a mutation found in two 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.
