A Phase II Open-Label, Multi-Center Study of a Group B Streptococcus Vaccine in HIV Positive and HIV Negative Pregnant Women
The study compared the magnitude of the antibody response and safety of a GBS Trivalent Vaccine in HIV positive and HIV negative pregnant women and their offspring. In addition the study investigated the maternal to fetal transfer of antibodies induced by the investigational vaccine.

Primary outcomes
- Geometric Mean Concentrations (GMCs) of Antibodies in Maternal Subjects and Infants at Delivery/Birth — Day of delivery/birth
GMCs of Group B Streptococcus (GBS)-specific Abs against serotypes Ia, Ib and III in mothers and in infants at delivery/birth are presented. - Geometric Mean Antibody Transfer Ratio Between Infant Antibody Level (μg/mL) and Maternal Antibody Level (μg/mL), for GBS Serotypes Ia, Ib and III at Delivery/Birth. — Day of delivery/birth
The Geometric mean transfer ratio of GBS-specific Ab against serotypes Ia, Ib and III at delivery is calculated as the geometric mean of the pairwise ratios between the antibody concentrations from infant at birth and to maternal serum concentration at delivery.
