Relative mean frequencies of CD4 T cells expressing 1, 2, 3, or 4 activation markers (adapted^† according-to-protocol cohort for cell-mediated immunity – RZV group only). M = month; RZV = adjuvanted recombinant zoster vaccine. Data labels represent percentages of mean frequencies of CD4 T cells expressing any combination of 1, 2, 3, or 4 activation markers from: CD40 ligand; interferon-γ, interleukin-2, tumor necrosis factor-α ^†Adapted denotes that for each time point presented, the corresponding according-to-protocol cohort was used.
