What Parents Need to Know About RSV
Navigating RSV protection can feel overwhelming, especially during your baby’s first cold and flu season.
This hub offers trusted resources from healthcare providers, answers to common questions, and guidance to help you understand the risks of RSV and explore options to help protect your family.
Why is RSV a concern for babies?
What is RSV?
RSV (respiratory syncytial virus) is a common virus that infects the lungs and airways. Most children will have RSV by the time they’re two. In healthy adults and older kids, it usually causes mild, cold-like symptoms — but in babies, it can lead to serious illness.
In Canada, around 2% of infants are hospitalized with RSV in their first year. In some remote communities, this can rise to 5–17%.
Fortunately, there are options to help lower the risk during RSV season.
RSV Protection Options
In Canada, there are options to help protect your baby during their first RSV season.
RSV Vaccine for Pregnant Mothers
Pregnant mothers can receive the RSV vaccine—called RSVpreF (ABRYSVO)—between 32 and 36 weeks of pregnancy.
How does it work?
This vaccine is given as a single dose and trains the mother’s immune system to produce RSV-fighting proteins called antibodies.
During the final weeks of pregnancy, the mother will pass these antibodies to the baby, which will help reduce the risk of severe RSV illness during the baby’s first RSV season.
RSV Immunization for Babies
Depending on when they are born, babies can receive the RSV immunization—called nirsevimab (Beyfortus)— either shortly after birth or at the start of RSV season.
It may also be offered to babies up to 24 months old entering their second RSV season, who are at a higher risk of serious illness from RSV—such as those born prematurely or with certain medical conditions.
How does it work?
This immunization is a single dose that gives the baby ready-made antibodies to help recognize and fight RSV. Because it doesn’t rely on the baby’s immune system to build protection, it begins working right away after it’s given to help reduce the risk of severe RSV illness.
Provincial RSV Programs
RSV protection options and public funding vary across Canada.
The map below shows which RSV protections are publicly funded and which are available for private purchase in each province and territory.

Patient Voices
From the anxiety of RSV hospitalizations, to the challenges of navigating protection options across Canada, hear directly from parents and caregivers as they share their experiences with RSV.
Katrina's Story
In 2023, Katrina’s two older kids came down with what seemed like a typical cold — runny noses, a cough, nothing too alarming. But when her seven-week-old baby caught the virus, everything changed.
“It all happened so fast,” Katrina recalls. “She went from having a bit of a cough to struggling to breathe, and suddenly in the middle of the night we were rushing to the hospital.”
Katrina’s daughter was placed on oxygen and they spent four days in the hospital.
“She was so tiny, connected to cords and monitors helping her breathe. Watching your newborn’s oxygen levels drop — that’s just not something you’re ever prepared for as a parent.”
At the time, there were no RSV protection options available. Now, Katrina is sharing her experience in hopes of building awareness and helping families understand how serious RSV can be.
“If you know you’re going to have an infant during respiratory season — especially if you have older kids in school or daycare, it’s so important to know your options,” says Katrina.
She hopes her story encourages other families to ask questions, learn what to watch for, and feel empowered to protect their little ones.
FAQ
What is RSV?
RSV (respiratory syncytial virus) is a common virus that infects the lungs and airways. Most children will have RSV by the time they’re two. In healthy adults and older kids, it usually causes mild, cold-like symptoms — but in babies, it can lead to much more serious illness.
How does RSV spread?
RSV spreads easily through coughing, sneezing and touching contaminated surfaces.
Babies can be exposed to RSV by family members who don’t even know they have it.
Why can RSV be serious for babies?
RSV can be very serious for babies—especially those born early or with weaker immune systems—because their lungs and immune systems are still developing.
In Canada, it’s the leading cause of hospital visits for infants with lung infections like bronchiolitis or pneumonia. Each year in Canada, around 2% of infants are hospitalized with RSV in their first year. In some remote communities, this can rise to 5–17%.
Can RSV cause long-term health risks?
Being infected with RSV as a baby can lead to long-term health issues, like a higher risk of asthma later in childhood.
A study in The Lancet found that babies who didn’t get RSV in their first year were about 26% less likely to have asthma by age five.
Another study found that RSV infections in early childhood are also associated with long-term wheezing and impaired lung function.
When is my baby at highest risk for RSV?
In Canada, RSV season usually starts in the fall (October or November) and lasts through late spring (March to May).
The exact timing can vary by region and from year to year, but most provinces see a rise in RSV cases beginning in late fall, with peak activity during winter months (December to February).
Is RSV protection safe?
Yes — both the maternal RSV vaccine and the infant RSV immunization for babies are safe and effective. They’ve been approved by Health Canada and are used worldwide to help protect babies from serious RSV illness.
Are there side effects from RSV protection?
It is possible to experience side effects from both the maternal RSV vaccine and infant RSV immunization for babies. Most side effects are mild and will go away on their own within a few days. The most common side effects are:
- Redness or pain where the vaccine or immunization was given
- Fatigue
- Body aches
How do I access RSV protection?
RSV protection programs vary from province to province. Talk to a healthcare provider to learn about what is available in your area.
