- The Percentages of Non-pregnant Subjects With Antibody Concentrations Above a Defined Threshold at One Month After the Second Vaccination. [ Time Frame: Day 61, one month after the second vaccination ]The percentages of non-pregnant subjects with antibody concentrations above a defined threshold per serotype after the administration of two vaccine doses administered one month apart. Defined thresholds for antibody concentrations, which exceed pre-defined serotype specific ELISA values are 1, 2, 3, 5 and 8 μg/mL.
- Antibody Geometric Mean Concentrations (GMC) in Non-pregnant Women at One Month After the Second Vaccination. [ Time Frame: Day 61, one month after the second vaccination ]Antibody GMC per serotype in non-pregnant women after receiving two doses of the study vaccine administered one month apart .
- The Percentages of Maternal Subjects With Antibody Concentrations Above a Defined Threshold at Day of Delivery. [ Time Frame: Day of delivery ]The percentages of maternal subjects with antibody concentrations above a defined threshold per serotype following the administration of one of three different doses of the study vaccine or placebo.Antibody concentrations which exceed pre-defined serotype specific ELISA values are 1, 2, 3, 5 and 8 μg/mL.
- Antibody GMC in Maternal Subjects at Day of Delivery [ Time Frame: Day of delivery ]Antibody GMC per serotype in maternal subjects at day of delivery following one administration of one of three different doses of the study vaccine or placebo are reported.
- The Percentages of Maternal Subjects With Antibody Concentrations Above a Defined Threshold Per Serotype at One Month After Vaccination. [ Time Frame: Day 31, one month after vaccination ]The percentages of maternal subjects with antibody concentrations above a defined threshold per serotype at one month after the administration of one of three different doses of the study vaccine or placebo. Antibody concentrations which exceed pre-defined serotype specific ELISA values are 1, 2, 3, 5 and 8 μg/mL.
- Antibody GMC Per Serotype in Maternal Subjects at One Month After Vaccination [ Time Frame: day 31 ]Antibody GMC per serotype in maternal subjects at one month after the administration of one of three different doses of the study vaccine or placebo.
- The Percentage of Non-pregnant Subjects With Antibody Concentrations Above a Defined Threshold at One Year After the First Vaccination. [ Time Frame: Day 361, one year after the first vaccination ]The percentage of non-pregnant subjects with antibody concentrations above a defined threshold per serotype after the administration of two vaccine doses one month apart. Antibody concentrations which exceed pre-defined serotype specific ELISA values are 1, 2, 3, 5 and 8 mcg/mL.
- Antibody GMC in Non-pregnant Subjects at One Year After the First Vaccination [ Time Frame: Day 361, one year after the first vaccination ]Antibody GMC per serotype in non-pregnant subjects after receiving two doses of the study vaccine administered one month apart, at one year after first vaccination.
- Number of Non-pregnant Subjects Reporting Solicited and Unsolicited Adverse Events [ Time Frame: Day 61 ]Number of non-pregnant subjects reporting solicited and unsolicited adverse events following 2 injections (1 month apart) of the trivalent GBS vaccine at a dose of 20/20/20 μg with aluminum at one month after second vaccination are reported.
- Number of Maternal Subjects Reporting Solicited and Unsolicited Adverse Events [ Time Frame: From day 1 to one year after delivery ]Number of maternal subjects reporting solicited and unsolicited adverse events following the administration of either one of three different doses of the study vaccine or placebo.
- Antibody GMC Per Serotype at Different Time Points in Infants [ Time Frame: Day 4, day 43 and day 91 after birth ]Antibody GMC per serotype on the day of birth, at 6 weeks and 3 months of age in infants born from women who received either one of three different doses of the study vaccine or placebo.
- Number of Infants Reporting Serious Adverse Events [ Time Frame: one year after birth ]Number of infants born from women who received either one of three different doses of the study vaccine or placebo who reported serious adverse events
