Phase I/II, double-blinded, placebo-controlled, randomized (1:1:1) multi-center study. Randomization will be stratified by HIV status and M.tb sensitization status. The study will enroll approximately 480 pre-adolescents (8-14 years of age inclusive) with or without HIV and with or without M.tb sensitization who received BCG vaccination at birth. Participants with HIV will be immunocompetent and virologically suppressed on antiretroviral therapy.~Participants will be randomized to one of three study product arms: VPM1002 Vaccine, BCG Vaccine, or Placebo. Each participant will receive a single intradermal injection of the assigned study product.
The purpose of this study is to assess whether Mycobacterium bovis rBCGΔureC::hly (VPM1002) vaccination and Mycobacterium bovis bacille Calmette-Guérin (BCG) revaccination are safe and immunogenic in pre-adolescents with and without HIV and with and without Mycobacterium tuberculosis (M.tb) sensitization.
