Longitudinal single cell profiling of epitope specific memory CD4+ T cell responses to recombinant zoster vaccine.

ABSTRACT: Vaccination leads to rapid expansion of antigen-specific T cells within in the first few days. However, understanding of transcriptomic changes and fates of antigen-specific T cells upon vaccination remains limited. Here, we investigate the fate of memory CD4+ T cells upon reactivation to recombinant zoster vaccine for shingles at cellular and transcriptional levels. We show that glycoprotein E-specific memory CD4+ T cells respond strongly, their frequencies remain high, and they retain markers of cell activation one year following vaccination. Memory T cells with the most dominant TCR clonotype pre-vaccination remain prevalent at year one post-vaccination. These data implicate a major role for pre-existing memory T cells in perpetuating immune repertoires upon re-encountering cognate anti
