Characterization of SARS-CoV-2 Variants B.1.617.1 (Kappa), B.1.617.2 (Delta), and B.1.618 by Cell Entry and Immune Evasion

10 Mar 2022

Abstract excerpt

SARS-CoV-2, the causative agent of pandemic COVID-19, is rapidly evolving to be more transmissible and to exhibit evasive immune properties, compromising neutralization by antibodies from vaccinated individuals or convalescent-phase sera. Recently, SARS-CoV-2 variants B.1.617.1 (Kappa), B.1.617.2 (Delta), and B.1.618 with mutations within the spike proteins were identified in India. In this study, we examined...
