Overview
Respiratory Syncytial Virus (RSV) is a common respiratory virus that usually causes mild, cold-like symptoms. However, it can be serious for infants, young children, older adults, and people with weakened immune systems. RSV is a leading cause of bronchiolitis (inflammation of small airways) and pneumonia in children under 1 year old. In the 2025-2026 season, RSV vaccines are now available for older adults and pregnant women (to protect newborns).
