Effect of human TRAM-encoding adenovirus in Rhesus macaques. Three groups of six Rhesus macaques were immunized with ChAd63-ME TRAP alone (a), or mixed with 5x ChAd63-hTRAM (b), or with 5x ChAd63-PfAMA1 (c), at weeks 0 and 8. The individual TRAP-specific IFNγ responses were measured by ELISPOT at several time points as indicated. Each line represents one animal. TRAP specific IFN-γ production was measured after adenovirus vaccination (data not shown) and one week post MVA boost by intracellular cytokine staining. Graphs represent the frequency of IFN-γ+ CD4+ T cells (d) or IFN-γ+ CD8+ T cells (e) in each group with each animal displayed as a single point and lines representing the median group response. Antibodies to TRAP were measured by LIPs with the graphs representing the fold increase in TRAP responses between the pre-vaccination timepoint and 4 weeks post adenovirus prime (f) and 3 weeks post-MVA boost (g). Each animal is represented by a single point with lines representing the median response per group.
