mRNA vaccination of naive and COVID-19-recovered individuals elicits potent memory B cells that recognize SARS-CoV-2 variants
Aurélien Sokal, et al.
To better understand B cell responses to SARS-CoV-2 mRNA vaccination, Sokal et al. analyzed memory B cells from COVID-19-recovered and naive individuals. In recovered individuals, vaccination amplifies a broad repertoire of matured MBCs and generates variant-neutralizing plasma cells. In naive individuals, vaccination induces an MBC pool containing potent neutralizing clones against all current variants of concern, including beta and delta.
