NEW YORK – 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 United Kingdom and South Africa, according to a laboratory study conducted by the US 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 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.
The Pfizer-BioNTech vaccine and the one from Moderna Inc, which use synthetic messenger RNA technology, can be quickly tweaked to address new mutations of a virus if necessary. Scientists have suggested the changes could be made in as little as six weeks. (Reuters)
