Epitope-Driven Polyfunctional Divergence of SARS-CoV-2 RBD Antibodies

Pierre Rosenbaum, Cyril Planchais, Timothée Bruel, Maxime Beretta, Isabelle Staropoli, William Bolland, Florence Guivel‐Benhassine, Delphine Planas, French COVID Cohort Study Group, CORSER Study Group, Olivier Schwartz, Hugo Mouquet

This study examines how SARS-CoV-2 RBD antibodies differ in function, showing that neutralizing antibodies lose effectiveness against variants but retain effector functions, while non-neutralizers remain broadly reactive but less effective overall.
