Respiratory Syncytial Virus
Respiratory syncytial virus (RSV) is a common respiratory virus that affects the lungs and airways. RSV can cause serious illness in infants, young children, older adults, and people with certain health conditions.
RSV season typically runs from late October to April, although the timing can vary from year to year.
Ontario's publicly funded RSV prevention program has expanded for the 2026-2027 respiratory illness season.
Older adults
You may be eligible for a publicly funded RSV vaccine if you:- Are 75 years of age or older
- Are 60 to 74 years of age and meet provincial high-risk eligibility criteria
Contact your primary care provider to book an appointment. If you received an RSV vaccine in a previous season, you do not need another dose at this time.
Not eligible for the publicly funded program?Adults aged 60 years and older who do not qualify for the publicly funded program may still receive the RSV vaccine through a pharmacy with a prescription from their healthcare provider.
The vaccine must be purchased privately, although some private insurance plans may cover part or all of the cost.
Pregnant individuals
Eligible pregnant individuals can receive the RSV vaccine (Abrysvo) to help protect their baby from severe RSV illness during the first months of life. Talk to your primary care provider to learn whether RSV vaccination is right for you.
High-risk infants and children
Eligible infants and children can receive Beyfortus®, a monoclonal antibody that helps protect against severe RSV illness.To provide protection throughout RSV season, eligible infants should receive Beyfortus in the fall. Protection lasts approximately six months. Talk to your primary care provider to confirm eligibility and book an appointment.
