Respiratory Syncytial Virus (RSV) Vaccination

Respiratory syncytial virus (RSV) is a highly contagious virus that causes respiratory infections in people of all ages. While most experience only mild cold-like symptoms, RSV can cause serious illness in infants, young children with certain medical conditions, and older adults, sometimes requiring hospital care.

What are the symptoms?

Symptoms usually appear 2 to 8 days after exposure and can include:

  • Runny nose

  • Cough

  • Wheezing or difficulty breathing

  • Fever

In babies under 12 months, RSV can lead to serious conditions like bronchiolitis or pneumonia, and may also contribute to long-term respiratory issues such as asthma.

How does RSV spread?

RSV spreads easily through droplets in the air or on surfaces when an infected person coughs, sneezes, or talks. You can become infected by:

  • Breathing in droplets

  • Touching contaminated surfaces, then touching your face

People are most infectious while they have symptoms.

Who is at higher risk of severe RSV?

  • Babies under 12 months (especially under 6 months)

  • Children under 2 with chronic lung or heart disease, or born prematurely

  • Older adults, particularly those with chronic conditions or weakened immune systems

  • Children with asthma, who may experience flare-ups
