IFN-γ T cell responses after challenge. Vaccinated and unvaccinated monkeys were challenged intratracheally with the Bilthoven WT strain of MeV. PBMCs were examined ex vivo without stimulation for production of IFN-γ (A and B) and after stimulation with pools of overlapping peptides from the H (C and D), F (E and F), and N (G and H) proteins. The data are presented as SFCs per 106 PBMCs for individual animals (A, C, E, and G) and as averages plus the SEM for each vaccine group (B, D, F, and H). For stimulated cells (C to H), the numbers of SFCs present without stimulation (A and B) have been subtracted.
