Pregnancy RSV vaccine effects on newborns, breastfeeding, and child health

Neonatal, Lactation, and Child Health Outcomes Following RSV Vaccination During Pregnancy

NIH-funded research Healthpartners Institute · NIH-11311951

This project looks at whether getting the RSV vaccine during pregnancy affects newborn health, breastfeeding, growth, development, and allergic outcomes in early childhood.

What this research studies

If you join, researchers will follow babies whose mothers got the prenatal RSVpreF vaccine and compare them with babies whose mothers did not get the vaccine. They will use medical records, brief surveys, and routine pediatric visit data to track newborn outcomes, breastfeeding experiences, growth, neurodevelopment, and allergic conditions over time. The team will pay special attention to preterm birth and early neonatal health because the original vaccine trial had limited data for people at high risk of early delivery. Participation may involve allowing access to your and your child’s health records and answering short questionnaires at intervals.

Who could benefit from this research

Good fit: Ideal participants are pregnant people who received (or plan to receive) the prenatal RSVpreF vaccine and their newborns and young children, particularly those receiving care at participating HealthPartners clinics.

Not a fit: People who are not pregnant, not planning pregnancy, or who did not receive the prenatal RSV vaccine are unlikely to gain direct benefit from participating.

Why it matters

Potential benefit: If successful, this research could provide clearer safety information to help parents and clinicians make informed decisions about RSV vaccination during pregnancy.

How similar studies have performed: A large clinical trial showed the vaccine cuts severe RSV illness in infants, but that trial excluded people at high risk for preterm birth and left unanswered questions about neonatal, lactation, and longer-term child outcomes.
