Documentation of infant HIV negative exposure or infection status with negative HIV ELISA and HIV DNA PCR tests. 7. Parent or legal guardian able and willing to provide signed informed consent. 8. Participant/parent/legal guardian able to attend all scheduled visits and to comply with all trial procedures. EXCLUSION CRITERIA 1. History of TB exposure in household or non-household contact. 2. History/Evidence of TB disease or infection. 3. Quantiferon positive. 4. Prior TST test. 5. Any one of Anemia, Neutropenia, Thrombocytopenia, SGPT (ALT), SGOT (AST) or Creatinine = Grade 2 6. Receipt of a live vaccine within 28 days prior to randomization. 7. Receipt or planned receipt of any investigational vaccine. 8. Known or suspected congenital immunodeficiency. 9. Receipt of immunosuppressive therapy or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months). 10. Known or suspected autoimmune disease 11. Hypersensitivity to any of the vaccine components, or history of a life-threatening reaction to a vaccine containing any of the same substances as the vaccine used in the trial. 12. Participation in another clinical trial for an investigational product (IP). 13. Bleeding disorder or receipt of anticoagulants in the 3 weeks preceding randomization, contraindicating IM vaccination. 14. Chronic illness that, in the opinion of the investigator, is at a stage where it might interfere with trial conduct or completion. 15. Febrile illness (temperature = 100.4°F [= 38.0°C]) within 24 hours prior to randomization. Note: A subject may enroll after recovery from febrile illness if the subject is still within the age window. 16. Systemic antibiotic use within 48 hours prior to randomization. |

---|---|---|---|---|
Other | Assess the immunogenicity of a 3-dose AERAS-404 regimen in HIV-uninfected, HIV-unexposed, BCG-primed infants. | T-cell response, as measured by Intracellular Cytokine Staining (ICS) following stimulation with peptide pools spanning the vaccine antigens, will be used to assess immunogenicity. | Subjects will be followed for up to 1 year and 4 months. | |
Other | Select an appropriate dose regimen for AERAS-404 in HIV-uninfected, HIV-unexposed, BCG-primed infants. | Safety and immunogenicity analyses will be reviewed for the selection of the appropriate dose regimen | After all subjects in Cohorts 4 and 5 have completed Study Day 126, the safety and immunogenicity data from these Cohorts will be evaluated. The data will inform the decision on the study vaccine dose for Cohort 6. | |
Other | Explore interactions between AERAS-404 and EPI vaccines. | Antibody concentration levels at 12 months of age for all Cohorts, and in addition at 28 days post second study vaccine dose (Study Day 56) for Cohort 6 will be presented. Summaries will include antibody titers to Tetanus toxoid vaccine (tetanus; given at 6, 10, 14 weeks of age), and Haemophilus influenza B conjugate vaccine (given at 6, 10, 14 weeks of age). Responses to other EPI vaccines may also be assessed. | Antibody concentration blood samples taken when subjects reach 12 months of age for all Cohorts and in addition, 28 post second study vaccine dose (Study Day 56) for subjects in Cohort 6 only. | |
Other | Assess the immunogenicity of a 2-dose AERAS-404 regimen in HIV-uninfected, HIV-unexposed, BCG-primed infants. | Subjects will have Immunology samples taken at multiple time points for up to 1 year and 4 months. | ||
Primary | Investigate the safety of AERAS-404 in HIV-uninfected, HIV-unexposed, BCG-primed infants. | Adverse Events and Serious Adverse Events (SAE) will be collected on subjects throughout their participation in the study. Solicited adverse events are captured 28 days post each vaccination. Evaluation of the safety profile of AERAS-404 will be performed using data from all subjects who received at least one dose and has 7 days of safety data, and will be summarized by cohort and treatment group. The number (percentage) of subjects with any adverse event (including solicited, unsolicited, and serious adverse events) will be summarized by Medical Dictionary for Regulatory Activities (MedDRA) system organ class and Preferred Term. Additional summaries will present the number (percentage) of subjects with any adverse events by severity and by relationship to study vaccine; parameters evaluable by the Aeras 404 Pediatric Toxicity Table provided in the protocol, will be summarized by severity corresponding to Toxicity Grade, as appropriate. | Subjects will be followed for up to 1 year and 4 months. | |
Secondary | Investigate the safety of a 3-dose AERAS-404 regimen in HIV-uninfected, HIV-unexposed, BCG-primed infants | The number and percentage of subjects who are enrolled into the three-dose regimen (Cohorts 4-6) with solicited and unsolicited AEs (including serious adverse events [SAEs], local and systemic reactions, and clinical laboratory values or vital sign values recorded as newly abnormal following study vaccination) recorded post-vaccination will be summarized to address the secondary safety objective of the study. Subjects in Cohorts 4 and 5 will be followed for : 1 year and 3 months, Cohort 6: 1 year 4 months and Solicited adverse events are captured 28 days post each vaccination. | Subjects will be followed for up to 1 year and 4 months. |
