RSV program update
The 2024-2025 Ontario RSV prevention program for infants, high-risk children and pregnant individuals has ended. If doses were not given, wait for recommendations expected in fall 2025.
The high-risk older adult RSV program will continue into late spring 2025.
The respiratory syncytial virus (RSV) causes respiratory illness, particularly in infants, young children, and older adults, affecting the lungs and airways. It can lead to a serious lung infection called bronchiolitis, which can cause difficulty breathing.
There are 2 RSV prevention programs in Ontario that take place before and during the RSV season, which is generally from late fall to spring.
- Infants and high-risk young children which also includes pregnant individuals.
- High-risk older adults.
Talk to your health care provider about protecting your family against RSV to help reduce your risk of severe illness.

If you don't meet publicly funded eligibility for the vaccine, you can pay for the vaccine at a pharmacy with a prescription from your health care provider.
