Pregnancy shot may shield newborns from deadly RSV – major brazil trial launches
NCT ID NCT07445763
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will check how well a new RSV vaccine (RSVpreF) works when given to pregnant women in Brazil. Researchers will follow 5,000 infants up to 6 months old who are hospitalized or seen in clinics for respiratory illness. By comparing babies whose mothers got the vaccine to those who didn't, they hope to measure real-world protection against severe RSV disease.
