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. ]

Hide Outcome Measure 1

Measure Type	Primary
Measure Title	To Evaluate the Safety Profile of MVA85A/AERAS-485 in Bacillus Calmette-Guerin (BCG) -Vaccinated, HIV-negative Infants.
Measure Description	Adverse events (AE) were collected for 28 days after vaccination. The subject's parent or guardian recorded information regarding occurrences of solicited adverse events in diary cards through 7 days after vaccination. Serious adverse events (SAE) were collected from the time of study vaccine dosing throughout the entire study. A safety cohort (the first 330 infants enrolled) also had serum chemistry and hematology testing up to 28 days post-vaccination.
Time Frame	AEs recorded 28 days post-vaccination; SAEs recorded for entire study period.

Population Description
