In this Monday, Dec. 14, 2020, file photo, a vial of the Pfizer-BioNTech vaccine for COVID-19 sits on a table at Hartford Hospital in Hartford, Conn. New research suggests that Pfizeru2019s 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. Photo: AP
