In a recent study published on the medRxiv* preprint server, a team of researchers tested the durability of antibodies produced by a vaccine-induced full-length severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein and receptor-binding domain (RBD). They also analyzed the antibody levels targeting the SARS-CoV-2 Omicron variant of concern (VOC), in younger adolescent children.
