Pfizer-BioNTech Vaccine Not Affected by Mutation Seen in Contagious Coronavirus Variant, Study Indicates
January 8, 2021
(STAT News) – A mutation found in fast-spreading coronavirus variants does not negate the Covid-19 vaccine from Pfizer and BioNTech, researchers reported late Thursday. The result is positive, if expected, evidence that existing vaccines will be able to withstand some mutations to the SARS-CoV-2 coronavirus without losing efficacy. But experts noted that this vaccine and others will still need to be tested against other mutations of concern, and that the new study only looked at one key mutation contained in the variants, not the full variants. “We’re working on that part now” in additional studies, Philip Dormitzer, Pfizer’s vice president and chief scientific officer of viral vaccines, told STAT.
