Ontario’s fall immunization campaign kicked off this week, with initial doses of flu and COVID-19 vaccines prioritized for high-risk groups starting the week of September 28. The province also expanded access to RSV vaccines, targeting infants, elderly residents, and those with specific health conditions, as respiratory illness season approaches.
Ontario’s Fall Immunization Programs Begin with Expanded Vaccine Access
High-Risk Groups to Receive Vaccines Starting September 28
The first wave of immunizations will focus on individuals aged 65 and older, hospitalized patients, hospital staff, and residents and staff in long-term care homes, retirement homes and other congregate settings. These groups are considered high-risk due to increased vulnerability to severe complications from respiratory illnesses. Sylvia Jones, Ontario’s Minister of Health, emphasized the importance of timely access, stating, “Our government is ensuring everyone has timely and convenient access to flu, COVID-19, and RSV immunizations close to home.”
RSV vaccines, including Abrysvo® and Arexvy, will be available year-round for Ontarians aged 60 to 74 who meet high-risk criteria or live in higher-risk settings, as well as those 75 and older. This expansion follows recent provincial updates to the adult RSV prevention program, aiming to reduce hospitalizations and severe outcomes in vulnerable populations.
General Public to Gain Access to Free Vaccines by October 26
Starting October 26, free flu and COVID-19 vaccines will be available to the general public through participating pharmacies, public health units, and participating doctor and nurse practitioner offices. This marks a shift from the initial prioritization phase, broadening eligibility to ensure widespread coverage. Dr. Kieran Moore, Ontario’s Chief Medical Officer of Health, urged residents to “stay up to date on recommended immunizations,” highlighting their role in preventing serious illness and maintaining community health.

The provincial government reiterated that vaccines in the routine immunization schedule are provided at no cost to eligible individuals. Those unsure of their eligibility are encouraged to consult healthcare providers or local public health units.
RSV Protection for Infants and Pregnant Women
Ontario’s RSV immunization strategy includes targeted measures for infants and pregnant women. Starting October 1, eligible newborns and infants up to eight months old in their first RSV season, as well as high-risk children up to 24 months in their second RSV season, can receive the Beyfortus immunization. Pregnant women are also eligible for the Abrysvo vaccine from an obstetrician, midwife or primary care provider to help protect their infant at birth.
Health officials noted that RSV poses the highest risk to infants under six months, particularly those with underlying conditions like chronic lung disease, congenital heart disease, weakened immune systems, or neuromuscular disorders. The provincial health advice line (811) remains available for 24/7 guidance on vaccine eligibility and health concerns.
Comparative Insights: U.S. and Ontario Vaccine Strategies
While Ontario’s program focuses on phased distribution, the U.S. faces uncertainty about vaccine coverage amid federal guidance gaps. According to CIDRAP, American insurers have pledged to cover updated flu and COVID-19 vaccines, but the CDC’s Advisory Committee on Immunization Practices has yet to provide guidance about either vaccine. In contrast, Ontario’s approach is more structured, with clear eligibility timelines and provincial oversight.
Both regions emphasize the importance of vaccinating high-risk groups. The U.S. is awaiting AAP recommendations for COVID-19 vaccines in children, whereas Ontario has already implemented measures for children under 24 months.
RSV vaccines prevent severe respiratory infections and hospitalization
RSV vaccines like Beyfortus and Abrysvo are designed to target specific age groups. These vaccines are critical in preventing severe respiratory infections, which can lead to hospitalization or long-term health complications.
