What is the goal of the study?
• Most adults have already had an RSV infection in their life, and so their bodies are already equipped with some RSV-fighting antibodies. Newborns and very young babies depend on antibodies that they receive from their mother through the placenta during pregnancy to defend against RSV during their first few months of life.
• In this study, researchers want to learn whether the study vaccine may help your body create even more RSV-fighting antibodies, and whether those antibodies may pass to your baby through the placenta.
• Researchers also want to learn whether the study vaccine is safe for pregnant women and their babies.
