Longitudinal dynamics of the human B cell response to the yellow fever 17D vaccine
A comprehensive understanding of the development and evolution of human B cell responses duced by pathogen exposure will facilitate the design of next-generation vaccines. Here, we utilized a gh-throughput single B cell cloning technology to longitudinally track the human B cell response to the llow fever virus 17D (YFV-17D) vaccine. The earlymemory B cell (MBC) response was mediated by both assical immunoglobulin M (IgM) (IgM(+)CD27(+)) and switched immunoglobulin (swIg(+)) MBC pulations; however, classical IgM MBCs waned rapidly, whereas swIg(+) and atypical IgM(+) and IgD(+)Â MBCs were stable over time. Affinity maturation continued for 6 to 9 mo following vaccination, providing evidence for the persistence of germinal center activity long after the period of active viral replication in peripheral blood. Finally, a substantial fraction of the neutralizing antibody response was mediated by public clones that recognize a fusion loop-proximal antigenic site within domain II of the viral envelope glycoprotein. Overall, our findings provide a framework for understanding the dynamics and complexity of human B cell responses elicited by infection and vaccination
