How a SARS-CoV-2 variant sacrifices tight binding for antibody evasion

Researchers have identified a SARS-CoV-2 variant that sacrifices tight binding to human cells in favor of evading the immune system, which could undermine current COVID-19 vaccines and therapies. The variant, B.1.351, has been found to reduce its binding to ACE2 receptors but decrease its binding to human antibodies.
