THE COVID-19 vaccine developed by Pfizer and BioNTech appears to be effective against emerging SARS-CoV-2 variants that spread more easily than other strains, early data suggest.
Researchers from Pfizer and the University of Texas Medical Branch tested antibodies from 20 people who received the vaccine as part of a phase 3 trial against a lab-generated SARS-CoV-2 virus containing a mutation that allows the spike protein to bind more effectively to its receptor.
The COVID-19 vaccine developed by Pfizer and BioNTech appears to work against variants of SARS-CoV-2 that make them more transmissible.

At least one of two or more new SARS-CoV-2 variants have likely made it into community spread in the United States, but they re unlikely to have much impact on vaccine effectiveness or standard precautions, CDC officials said at a briefing.
The first reported U.S. case of the highly transmissible coronavirus variant first seen in Great Britain (dubbed SARS-CoV-2 VUI 202012/01) was confirmed on Tuesday in a Colorado man with no travel history. The strain may be at least 56% and up to 70% more transmissible than the wild type virus, although not more severe or more deadly. The British variant has likely been circulating there since September 2020.
