BCG-immunised mice are protected against M. tb infection 26 weeks post-immunisation. IN or ID BCG-immunised mice were challenged 26 weeks later with M. tb via aerosol. Four weeks post-challenge, CFU were enumerated in lung and spleens. Individual log10 CFU values are shown with bars indicating mean ± SEM (n ≥ 5). One-way ANOVA with Tukey’s post-test for significance; ****P < 0.0001; **P < 0.01
