  Outcome Measures
  Show All 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 ]
  Hide Outcome Measure 6

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  

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
