Antigen-specific T cells (frequency and number) at baseline and positive time point. Values are given in percentage of positive cells gated on CD8+ population for tetramer staining (n = 17), percentage of positive cells gated on CD4+ or CD8+ populations for intracellular cytokine (ICS) staining (n = 26) and SFC/1×106 total PBMCs for IFN-γ ELISpot (n = 14). Responses are showing the maximum increase post-baseline compared with baseline irrespective of the time point
