Who Needs an RSV Vaccine? Groups at Greater Risk of Complications

As the respiratory virus season begins, attention is returning to respiratory syncytial virus, or RSV. The common virus causes mild, cold-like symptoms in many people, but it can lead to more serious illness in vulnerable groups.

Infants, older adults and people with weakened immune systems are among those at greater risk of complications. Underlying heart or lung conditions can also increase the likelihood of severe illness.

RSV can affect the lower airways, causing conditions such as bronchiolitis or pneumonia. Breathing difficulties, poor feeding in babies or worsening symptoms require prompt medical attention.

Vaccination recommendations depend on age, health conditions and local guidance. RSV vaccines may be recommended for older adults and during pregnancy to help protect newborns, while eligible infants may receive preventive antibodies rather than a vaccine.

Anyone considering RSV protection should ask a healthcare professional which option is appropriate and available. Handwashing, covering coughs and avoiding close contact with people who are ill can also help reduce the spread of respiratory infections.
