NEW YORK (Reuters) - Pfizer Inc and BioNTech's COVID-19 vaccine appears able to protect against a key mutation in the highly transmissible new variants of the coronavirus discovered in Britain and South Africa, according to a laboratory study conducted by the U.S. drugmaker.
The study by Pfizer and scientists from the University of Texas Medical Branch, which has not yet been peer-reviewed, indicated the vaccine was effective in neutralizing variants with the so-called N501Y mutation, situated on a portion of the virus that it uses to enter and infect cells.
