Quick facts
- This Fall, Ontario has two RSV prevention programs, both with expanded eligibility:
- High-risk older adult RSV vaccine program: In addition to last year’s eligibility seniors, this program has expanded to include residents of all retirement homes in 2024–25 (see below for complete eligibility list).
- Infant and high-risk children RSV prevention program: This program has expanded to include all infants born in 2024, who are less than 12 months of age and children under 24 months of age with high-risk medical conditions. The expansion includes a switch to a new monoclonal antibody, Beyfortus (nirsevimab), which is the preferred product for protecting infants from RSV and will be available in the Fall.

Key messages for healthcare providers
High-risk older adult RSV vaccine program
- The RSV vaccines available for the 2024-25 season are Arexvy (GSK) and Abrysvo (Pfizer).
- The publicly-funded High-Risk Older Adult program (external link) includes individuals who are aged 60 years and older and are also:
- residents of long-term care homes, Elder Care Lodges, or retirement homes
- patients in hospital receiving alternate level of care (ALC) including similar settings (for example, complex continuing care, hospital transitional programs)
- patients receiving hemodialysis or peritoneal dialysis
- recipients of solid organ or hematopoietic stem cell transplants
- individuals experiencing homelessness
- individuals who identify as First Nations, Inuit, or Métis
- Eligible older adults will be able to receive a single publicly funded dose of either Arexvy or Abrysvo if they have not previously received a dose.
- Re-immunization is not required for individuals who were vaccinated last year; studies indicate that the RSV vaccine offers multi-year protection.
- Long Term Care and Retirement Home residents should receive an RSV vaccine through their residences. Eligible dialysis and transplant recipients should receive an RSV vaccine through the dialysis/transplant unit. Other eligible people may receive an RSV vaccine through their primary care provider.
- Facilities and community health care providers can order RSV immunizing products for individuals who are eligible for a publicly-funded dose. See Ordering and Distribution below for more information.
- Individuals 60 years of age and older who do not qualify for a publicly funded dose of the RSV vaccine can purchase the vaccine with a prescription through their local pharmacy. Publicly funded RSV vaccine is not available in pharmacy.
Infant and high-risk children RSV prevention program
- The preferred product for Ontario’s infant RSV prevention program (external link) is the monoclonal antibody, Beyfortus (nirsevimab).
- National Advisory Committee (NACI) (external link) preferentially recommends Beyfortus based on its efficacy, duration of protection and safety profile.
- For the 2024-25 RSV season, Beyfortus is publicly-funded for children who are residents of Ontario and meet any of the following criteria:
- born in 2024 prior to the RSV season and are less than 12 months of age (NACI specifically recommends that infants 8 months of age or less be immunized)
- born during the 2024–25 RSV season
- high-risk children up to 24 months of age who remain vulnerable from severe RSV disease through their second RSV season, with:
- chronic lung disease of prematurity (CLD), including bronchopulmonary dysplasia/chronic lung disease
- hemodynamically significant congenital heart disease (CHD)
- severe immunodeficiency
- Down Syndrome/Trisomy 21
- cystic fibrosis with respiratory involvement and/or growth delay
- neuromuscular disease
- severe congenital airway anomalies impairing the clearing of respiratory secretions
- Beyfortus provides immediate protection and is most efficacious for the six months after administration. It should be given shortly after birth for infants born during the RSV season and just prior to the RSV season for eligible infants and children born before the season begins.
- The specific start and end dates for the 2024–25 RSV season are based on provincial epidemiology and will be communicated by the province and are usually from November to April. • Details about Beyfortus ordering and distribution will be shared in mid to late October, when this product is anticipated to be available.
- Abrysvo RSV vaccine is also available to pregnant individuals, who will deliver near the start of or during the RSV season, for protection of the infant.
- As Beyfortus is the preferred product for infant RSV protection, Abrysvo during pregnancy may be considered for pregnant individuals, where Beyfortus would not be agreed to or available (e.g., not giving birth in Ontario).
- If used, Abrysvo should be given between 32 and 36 weeks gestation.
- Using both the vaccine and monoclonal antibody is not necessary, unless the infant is high-risk (e.g., monoclonal antibody is recommended for all infants with certain medical conditions) or born within 14 days of vaccine administration.
- NB: Arexvy is not authorized for use in pregnancy.
- Additional resources to support the infant RSV prevention program are posted on the Ministry of Health’s website (external link) and can be used to counsel patients.
