Maternal RSV vaccination cuts infant hospitalization risk by over 80%, major study finds

Respiratory syncytial virus (RSV) is a common virus that can cause severe respiratory illness in infants and young children, including lower respiratory tract infections (LRTIs) such as bronchiolitis and pneumonia. It is a leading cause of infant hospitalization worldwide, with early-life infection linked to potential longer-term effects including recurrent wheeze or asthma, repeat hospital admissions and impaired lung health.
