B.C. flu season off to early start with H1N1 strain hitting harder this year

British Columbia's respiratory illness season is off to an early start, with influenza cases beginning to rise. Provincial health officer Dr. Bonnie Henry rolled out the province's immunization program Wednesday, warning that this year's flu season is being driven largely by the H1N1 strain, which typically peaks earlier and causes more severe illness in older adults.

COVID-19 and RSV virus remain relatively low across the province. Influenza is now at moderate levels in B.C.

The updated vaccine protects against three strains: H3N2, H1N1, and influenza B. Notifications have already gone out to residents most at risk, with appointments starting Tuesday. Notifications will continue and expand to the general population through early November.

RSV vaccine is available for free to those over 75, First Nations people over 60, and Métis people over 60. Vaccines against pneumococcal disease are also available. Nationally, influenza A is the most dominant strain, mostly affecting those over 65.

Dr. Henry said it's too early to predict whether this year's flu will be more severe. "While the severity of any respiratory season is hard to predict, getting vaccinated in the fall continues to be a known best way to lower our risk of severe illness, needing hospital care, or missing out on important activities," she said. The province confirmed there will be enough vaccines for everyone who is eligible.
