Flow cytometry data collected following vaccination indicate that both VP35m infection and rVSV-EBOV-GP vaccination both induce increases in the frequencies of proliferating CD4 and CD8 memory subsets and B cells, with proliferative bursts in VP35m infection occurring earlier (3–14 dpi) than that after vaccination (~14 DPV) [98,99,149]. Here, CD8A is linked to infection.
