Respiratory syncytial virus
RSV program update
RSV immunization is available for eligible adults, pregnant individuals, infants and high-risk children.
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.
RSV is most active from November to April.
There are 2 RSV prevention programs in Ontario:
- Infants and high-risk children which also includes pregnant individuals.
- Adults.
Talk to your health care provider about protecting your family against RSV to help reduce your risk of severe illness.

Infants born on or after April 1, 2026, and 8 months old or younger at the time of immunization are eligible for the RSV monoclonal antibody (called Beyfortus) during the RSV season. Children up to 24 months old who have certain medical conditions that put them at higher risk for severe RSV illness are also eligible.
The monoclonal antibody works by giving your child ready-made antibodies, offering immediate protection against RSV. It can be given at birth in the hospital or after birth at your doctor’s office.
Beyfortus is not being offered at Peel Public Health clinics. Contact any of the following locations for availability.
Primary care providers
If you have a primary care provider (doctor, nurse practitioner or midwife), they can order the monoclonal antibody (Beyfortus). Talk to your primary care provider (doctor, nurse practitioner or midwife) about how and where your baby can receive Beyfortus.
Additional options
The providers listed may offer the monoclonal antibody (Beyfortus) to eligible infants and children without a primary care provider. Since this list is not updated regularly and services may change, we recommend contacting the clinic or checking their website for the latest information.
