Naturally Immune People Develop Ultrapotent Antibodies Against Variants

Ultrapotent antibodies against diverse and highly transmissible SARS-CoV-2 variants

Defenses against SARS-CoV-2 variants

Our key defense against the COVID-19 pandemic is neutralizing antibodies against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus elicited by natural infection or vaccination. Recent emerging viral variants have raised concern because of their potential to escape antibody neutralization. Wang et al. identified four antibodies from early-outbreak convalescent donors that are potent against 23 variants, including variants of concern, and characterized their binding to the spike protein of SARS-CoV-2. Yuan et al. examined the impact of emerging mutations in the receptor-binding domain of the spike protein on binding to the host receptor ACE2 and to a range of antibodies. These studies may be helpful for developing more broadly effective vaccines and therapeutic antibodies. READ FULL STUDY
