abstract = {Memory B cells (MBCs) formed over the individual's lifetime
constitute nearly half of the circulating B cell repertoire
in humans. These pre-existing MBCs dominate recall responses
to their cognate antigens, but how they respond to
recognition of novel antigens is not well understood. Here,
we tracked the origin and followed the differentiation paths
of MBCs in the early anti-spike (S) response to mRNA
vaccination in SARS-CoV-2-naive individuals on single-cell
and monoclonal antibody levels. Pre-existing, highly mutated
MBCs showed no signs of germinal center re-entry and rapidly
developed into mature antibody-secreting cells (ASCs). By
contrast, and despite similar levels of S reactivity, naive
B cells showed strong signs of antibody affinity maturation
before differentiating into MBCs and ASCs. Thus,
pre-existing human MBCs differentiate into ASCs in response
to novel antigens, but the quality of the humoral and
cellular anti-S response improved through the clonal
selection and affinity maturation of naive precursors.},
