Can a pregnancy vaccine shield newborns from RSV? new study investigates
NCT ID NCT07249320
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study examines how well the ABRYSVO vaccine works when given during pregnancy to prevent RSV in infants. Researchers will compare health outcomes of babies born to vaccinated mothers versus unvaccinated mothers using electronic medical records. The goal is to see if the vaccine reduces RSV-related hospitalizations and other illnesses in the first months of life.
