Antibody feedback contributes to the development of Omicron-reactive memory B cells (Inoue-Kurosaki G, in JEM)

In contrast to a second dose of the SARS-CoV-2 mRNA vaccine, a third dose elicits potent neutralizing activity against the Omicron variant. Takeshi Inoe, Tomohiro Kurosaki (Lymphocyte Differentiation, IFReC), and the research group showed that pre-generated antibodies modulate the selection of GC and subsequent memory B cells after the second vaccine dose, accumulating more Omicronreactive memory B cells over time, which contributes to the generation of Omicron-neutralizing antibodies elicited by the third vaccine dose.
