  Outcome Measures

1.  Primary:   To Evaluate the Safety Profile of MVA85A/AERAS-485 in Bacillus Calmette-Guerin (BCG) -Vaccinated, HIV-negative Infants.   [ Time Frame: AEs recorded 28 days post-vaccination; SAEs recorded for entire study period. ]
  Show Outcome Measure 1

2.  Secondary:   To Evaluate the Efficacy of the MVA85A/AERAS-485 Vaccine Compared to Controls in Prevention of Tuberculosis Using an Endpoint Derived From Epidemiological Cohort Surveys in BCG Vaccinated Infants.   [ Time Frame: 15 to 36 months post-vaccination ]
  Show Outcome Measure 2

3.  Secondary:   To Evaluate the Immunogenicity of the MVA85A/AERAS-485 Vaccine Compared to Controls as Described by Flow Cytometric Intracellular Cytokine Staining of CD4 and CD8 T Cells.   [ Time Frame: 28 days post-vaccination ]
  Show Outcome Measure 3

4.  Secondary:   To Evaluate the Immunogenicity of the MVA85A/AERAS-485 Vaccine Compared to Controls as Described by the ex Vivo Enzyme Linked Immunospot (ELISPOT) Test Used in Previous MVA85A/AERAS-485 Human Trials.   [ Time Frame: 7 days post-vaccination ]
  Show Outcome Measure 4

5.  Secondary:   To Evaluate the Immunogenicity of the MVA85A/AERAS-485 Vaccine Compared to Controls as Described by the University of Capetown (UCT) Whole Blood Intracellular Cytokine Assay.   [ Time Frame: 28 days post-vaccination ]
  Show Outcome Measure 5

6.  Secondary:   To Discover Correlates of Protection From Tuberculosis in Infants Vaccinated With MVA85A/AERAS-485.   [ Time Frame: 15 to 36 months post-vaccination ]

Measure Type Secondary
Measure Title To Discover Correlates of Protection From Tuberculosis in Infants Vaccinated With MVA85A/AERAS-485.
Measure Description Investigations for determining correlates of immune protection to TB will not be completed as planned because the study did not show TB protection in MVA85A/AERAS-485 recipients.
Time Frame 15 to 36 months post-vaccination
