Pfizer/BioNTech vaccine appears effective against mutation in new coronavirus variants – study

NEW YORK, Jan 7 (Reuters) – Pfizer Inc and BioNTech’s COVID-19 vaccine appeared to work against a key mutation in the highly transmissible new variants of the coronavirus discovered in the UK and South Africa, according to a laboratory study conducted by the U.S. drugmaker.

The not-yet peer reviewed study by Pfizer and scientists from the University of Texas Medical Branch indicated the vaccine was effective in neutralizing virus with the so-called N501Y mutation of the spike protein.

The mutation could be responsible for greater transmissibility and there had been concern it could also make the virus escape antibody neutralization elicited by the vaccine, said Phil Dormitzer, one of Pfizer’s top viral vaccine scientists.

The study was conducted on blood taken from people who had been given the vaccine. Its findings are limited, because it does not look at the full set of mutations found in either of the new variants of the rapidly spreading virus.

  1. Pfizer Inc. and BioNTech SE raised their Covid-19 vaccine production target for this year to 2 billion shots, as the partners respond to a global rush of countries seeking to order more doses.

    The drugmakers have already committed more than half that capacity, BioNTech said in a presentation filed Monday. A more than 50% boost from the previous 2021 target of 1.3 billion doses, the increase incorporates a label change that will allow doctors to extract six doses instead of five from each vaccine vial, BioNTech said.
