Summary

This study tests a vaccine given to pregnant women to see if it can protect their babies from group B streptococcus (GBS) infection, a serious illness in newborns. Healthy pregnant women aged 49 or younger, between 24 and 36 weeks of pregnancy, can join. Participants receive one shot of either the GBS vaccine or a placebo (saltwater), and researchers monitor both mothers and infants for safety and immune response for up to 14 months after delivery.
