Bacille Calmette-Guérin (BCG) vaccination induces a marked increase in the interferon (IFN)–γ response to Mycobacterium tuberculosis purified protein derivative (Mtb PPD) in UK adolescents, but not in Malawian adolescents. We hypothesized that Mtb PPD-induced IFN-γ after BCG vaccination would be similar in infants from these 2 countries. Infants were vaccinated with BCG during the first 3–13 weeks of life. Three months after BCG vaccination, 51 (100%) of 51 UK infants had an IFN-γ response to Mtb PPD, compared to 41 (53%) of 78 of Malawian infants, in whom responses varied according to their season of birth. We conclude that population differences in immune responses after BCG vaccination are observed among infants, as well as among young adults.
