From: Age-related waning of immune responses to BCG in healthy children supports the need for a booster dose of BCG in TB endemic countries

Figure 3

The frequencies of Ki67+ CD4 and IFNγ expressing Ki67 CD4+ T cells following stimulation with BCG (A) or SEB (B) for 6 days are shown. Ki67 proliferation and expression of IFNγ in response to BCG stimulation in vitro wanes with increasing age, however non-specific proliferation due to SEB increases with increasing age. Horizontal bars represent median values.
