Manitoba Health Officer Urges Flu Vaccination Amid Mismatch Concerns

Manitoba’s chief provincial public health officer, Dr. Brent Roussin, is strongly encouraging residents to receive their influenza vaccinations despite concerns regarding the effectiveness of this year’s flu vaccine against the latest H3N2 mutation. This appeal follows a notable increase in influenza cases in the region, raising alarms about public health and safety.

During a recent statement, Dr. Roussin emphasized that the current vaccine, which targets various strains of influenza A and B, remains the best defense against severe outcomes of the virus. “It’s really important that the discussion that there could be a possible mismatch shouldn’t affect anybody’s ability or anyone’s decision to receive that vaccine, because it’s still our best protection,” he said.

In the past few weeks, Manitoba has experienced a significant rise in influenza positivity rates, primarily attributed to the H3N2 subtype of influenza A. Dr. Roussin noted that this subtype is known for its ability to mutate, often resulting in more severe cases and earlier spread compared to influenza B.

The effectiveness of the current vaccine will not be fully assessed until mid to late season when healthcare professionals can analyze ongoing data. Dr. Roussin stated that while the vaccine may not provide perfect protection against the illness, it is typically effective in preventing severe health outcomes.

According to the provincial respiratory virus surveillance report, there have been a total of 556 influenza cases reported across Manitoba since late August, including 111 cases in the Prairie Mountain Health region alone. Between November 23 and November 29, there were 41 new cases confirmed in that area. Dr. Roussin pointed out that while children under five are at higher risk, severe outcomes can occur in all age groups.

The report also indicated that there were 1,623 respiratory-related visits to emergency departments in Manitoba starting the week of November 23, with 46 flu-related hospital admissions and three deaths attributed to influenza. Dr. Roussin stressed the importance of taking seasonal influenza seriously, noting that severe outcomes are often seen in unvaccinated individuals.

In addition to influenza vaccinations, Dr. Roussin recommends that everyone over the age of six months consider receiving both the COVID-19 and influenza vaccines. He highlighted that these vaccines have established safety profiles and are effective in reducing the risk of severe illness.

Since August, the province has administered over 205,000 COVID-19 vaccines and 288,000 flu shots. Vaccination clinics are distributed across more than 1,000 health-care clinics, pharmacies, and hospitals in Manitoba, ensuring accessibility for residents.

Dr. Roussin also pointed out that misinformation surrounding vaccines is prevalent, making it crucial for individuals to discuss any concerns with their healthcare providers. He urged residents to remain vigilant in limiting the spread of respiratory viruses by practicing good hygiene, such as frequent handwashing and staying home when ill.

As the flu season progresses, Prairie Mountain Health has organized pop-up vaccination clinics across various locations, including the Brandon Friendship Centre and Shoppers Mall in Brandon. Although these community clinics are winding down, Jan Loe, director of public health services for Prairie Mountain Health, encouraged continued vaccination efforts and consultations with local health professionals.

With an ongoing risk from respiratory viruses, authorities are keen to ensure that residents are informed and protected against potential health threats this season.
