UK study finds RSV vaccine cuts infant hospitalizations by over 80%.

A major UK study found that vaccinating pregnant women against respiratory syncytial virus (RSV) reduces infant hospitalizations by over 80% when the vaccine is given at least two weeks before birth. The research, involving nearly 290,000 infants, showed the protection rises to nearly 85% when the shot is administered four or more weeks before delivery. Health officials say the findings support the national vaccination program that began in September 2024.
