A treatment of two monoclonal antibodies against SARS-CoV-2 is ninefold less effective in the lab against the B.1.351 variant than against the dominant version of the virus.
Researchers identify deletions in the N-terminal domain of the spike protein that allow the coronavirus to avoid antibody neutralization and that may contribute to the emergence of new variants.
Scientists across the world are closely tracking the spread of mutations in the coronavirus and investigating whether they could render current vaccines less effective.
New data suggest that the company’s approved COVID-19 vaccine protects against different virus variants, but could be less effective against the one that originated in South Africa.
