Immunogenicity of Seven New Recombinant Yellow Fever Viruses 17D Expressing Fragments of SIVmac239 Gag, Nef, and Vif in Indian Rhesus Macaques
Figure 8
Breadth of vaccine-induced, SIV-specific T-cell responses in rYF17D/rAd5 and rAd5 vaccinees.
We determined the breadth of T-cell responses in each animal by adding the number of positive IFN-γ ELISPOT assay responses to peptide pools (15mers overlapping by 11 amino acids) spanning the regions of Gag, Nef, and Vif covered in the SIVmac239 inserts. Panels A and B show the median breadth of T-cell responses to Gag, Nef, Vif, and all three proteins combined in the rYF17D/rAd5 (A) and rAd5 (B) groups. C) Comparison of the total number of peptide pools recognized in rYF17D/rAd5- and rAd5-vaccinated animals. Lines represent the median total number of responses in each group. We used the Mann-Whitney test to determine the p value.
