Memory B cells induced by mRNA vaccine may help generate antibodies against Omicron

In a recent research article published in the journal of Science Immunology, a team of researchers from Japan performed longitudinal analysis on the cellular composition of receptor-binding domain (RBD) memory B cell subsets and its antibody binding and neutralizing activity against the Beta, Delta, and Omicron variants following the second dose of a messenger ribonucleic acid (mRNA) vaccine.
