Macaque IFN-γ ELISpot responses.

<p>Male rhesus macaques were immunized i.d. at weeks 0 and 6 with either 10⁸ PFU MVA-Ag85A or MVA-Ag85A IMX313 and the response to antigen 85A measured in the blood by IFN-γ ELISpot before vaccination (pre) and every 2 weeks from week 1 onwards. Graphs represent the response of each individual animal to a single pool containing all antigen 85A peptides (<b>A</b>) or the sum of 7 separate peptide pools (<b>B</b>). <b>C</b>) Graphs represent the ELISpot responses of frozen PBMCs to a pool of antigen 85A peptides, a pool containing IMX313 peptides and a pool containing hC4bp peptides, pre-vaccination and at week 1 or week 7 post-vaccination. Bars represent the median group response with each animal displayed as a single point. Data was analyzed with a 2-way analysis of variance with a post-hoc Bonferroni test; the asterisks denote the level of statistical significance (*p<0.05).
