Pre-Assignment Details

Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
In case of discrepancy between the HIV results (DNA PCR positive, viral load negative), performed at the Screening Visit (one week prior to first vaccination) the infants were not enrolled in the study.
