Covid Antibody That Protects Against Broad Range Of Variants Identified
NDTV
The SARS-CoV-2 virus uses a protein called spike to attach to and invade cells in the body's respiratory tract.
Researchers have identified an antibody that is highly protective at low doses against a wide range of variants of the SARS-CoV-2 virus which causes COVID-19. The findings, posted as a pre-proof in the journal Immunity, could help develop new antibody-based therapies that are less likely to lose their potency as the virus mutates. The new antibody attaches to a part of the virus that differs little across the variants, meaning that it is unlikely for resistance to arise at this spot, the researchers said. "Current antibodies may work against some but not all variants," said study senior author Michael S Diamond, a professor at Washington University School of Medicine in St Louis, US.More Related News
