Immunogenicity and protective efficacy of CysVac2 across different MHC haplotypes. BALB/c (n=6) or Q(s) mice (n=6) were vaccinated s.c. with BCG, or three times with CysVac2 formulated in MPL/DDA. Twelve weeks after the first vaccination, the mice were challenged with ~100 CFU of M. tuberculosis by aerosol route and 4 weeks later they were killed and the bacterial load assessed in the lung. The data are presented as Log10 of the mean of CFU±s.e.m. (a, b). The frequency of CysVac2-specific CD4+ T cells producing IFN-γ, IL-2 or TNF (c, e) or IL-17 (d, f) was determined in lung cells stimulated ex vivo with CysVac2 protein in the presence of brefaldin A. The significance of differences between groups was determined by one- or two-way analysis of variance (ANOVA) (NS=not significant; *P<0.05; **P<0.01; ***P<0.0001).
