Alberta government maintaining COVID vaccine fee as it prepares for fall influenza campaign

Province says Albertans can start booking vaccination appointments on Oct. 5

The Alberta government says its provincewide influenza, COVID and respiratory syncytial virus vaccination campaign will begin next month.

In a news release issued Monday, the province said it’s maintaining the $100 fee it brought in last year for those seeking the COVID vaccine, though there’s a long list of reasons that could see the fee be waived for people, such as having health conditions that put them at risk for severe illness.

Linsey Marr, an environmental engineer, stood next to a pair of clear plastic boxes packed with tubes, nozzles and electronics, an odd-looking prototype that one day might serve to protect children in day care from airborne pathogens.

A nozzle filled the right-hand box with a faint silvery mist. A pump pulled some of that air into the left-hand box, where a sampler trapped floating particles and droplets. Soon, a digital screen bolted to the box turned red: “Detected! Dust mite allergen Der f 1.”

A protein shed by dust mites, Der f 1 can trigger asthma attacks when inhaled. Dr. Marr’s device had detected 843 picograms of Der f 1 per cubic meter. A single grain of salt is about 10 million times as heavy.

Hospitalization rates for illnesses like COVID, flu have doubled since pre-pandemic, report finds

Vaccine-preventable respiratory infections sending thousands to hospital, all while vaccine uptake is dropping

Years after the virus that causes COVID-19 kicked off a global pandemic, it’s still sending thousands of Canadians into hospital each year alongside other respiratory infections — despite a suite of vaccines that can slash someone’s risk of serious illness.

Striking new data from the Canadian Institute for Health Information (CIHI) shows hospitalization rates for vaccine-preventable respiratory diseases more than doubled in 2024 compared to pre-pandemic levels, all while vaccination rates are backsliding.

There were 142 hospitalizations for every 100,000 Canadians that year, the data shows, up from roughly 66 per 100,000 in 2019.

The Food and Drug Administration reversed its decision on Moderna’s flu vaccine and has agreed to review it for possible approval.

Just last week, Moderna announced that the agency had rejected its application for review of a new flu vaccine. The F.D.A. said the company’s research design had been flawed.

FDA declines to review Moderna application for new flu vaccine

Moderna requests meeting to discuss refusal as decision could have implications for all new and updated vaccines

US regulators will not review Moderna’s request to license a new, potentially more effective flu shot – even though the US Food and Drug Administration (FDA) previously gave the green light to the project – in a decision that could have implications for all new and updated vaccines in the US.

It’s the latest move by the Trump administration against vaccines. Officials in January decided to stop fully recommending one-third of routine childhood vaccines, including flu vaccines.

“This is likely to discourage industry from investing in future influenza vaccines, and makes working with the US FDA uncertain and problematic,” said Dorit Reiss, professor of law at UC Law San Francisco.

The Secret Weapon in Canada’s Sewers

As America takes an axe to its health data, expanding wastewater surveillance could save lives

As a virologist, I spend my days thinking about how to detect outbreaks of coronaviruses, mpox, West Nile and other pathogens early enough to stop them. Right now, I’m concerned about Canada’s awful flu season and the fact that we recently lost our measles-elimination status. But mostly, I’m terrified of what’s unfolding south of the border.

The consequences of the Trump administration’s cuts to the CDC and NIH will extend far beyond America. Those agencies form the backbone of North America’s infectious-disease surveillance. They track variants, monitor cross-border spread and feed data into global systems coordinated by the World Health Organization, helping everyone on Earth prepare. When those programs are dismantled, Canada loses key warning signs of influenza, RSV, measles and whatever diseases are coming next.

Nationally, we are seeing very high levels of influenza and, again, a growing wave of COVID-19 infections. A new variant of influenza A H3N2 called subclade K is driving some of this epidemic. Subclade K has already appeared in Japan and Europe and is more severe, especially in the elderly and very young.

Last week, the Center for Infectious Disease Research and Policy reported 39,945 hospital admissions^⁠, up from 33,301 admissions the week before. While numbers have varied some week to week, they have been relatively high. There have been 19 pediatric deaths so far this season. The CDC estimates that there have been at least 15,000,000 illnesses, 180,000 hospitalizations, and 7,400 deaths from flu so far this season.

Health and Human Services (HHS) Secretary Robert F. Kennedy Jr. today appointed two obstetricians-gynecologists to the Advisory Committee on Immunization Practices (ACIP). Both appointees have a history of questioning vaccine safety in pregnancy, and one has erroneously claimed COVID-19 vaccines caused miscarriages.

Adam Urato, MD, of UMass Memorial Health, is the first listed appointee to ACIP. In October of 2024, he wrote on X, “CDC & ACOG recommend 4 vaccines in pregnancy: Flu, Tdap, RSV, & COVID. My patients often ask: ‘How do we know that all these vaccines won’t have adverse effects on my baby & me?’ The answer is: ‘We don’t.’ Women’s vax concerns should be acknowledged & their choices supported.”

Canadian doctors are warning that a new U.S. policy which slashes the number of vaccines universally recommended to all children could have devastating, and potentially deadly effects in Canada, including increasing disease spread through American travellers visiting north of the border.

“This was just incomprehensibly stupid. I was horrified,” said family doctor and former president of the Ontario Medical Association, Dr. Sohail Gandhi in an interview with CTV News Saturday. “Children in the U.S. are going to die as a result of this move – and, worse, some children are going to have lifelong complications as a result of this move.”

As H3N2 sweeps across Canada, what to know about flu’s heart attack risk

Published December 23, 2025

Published on: December 23, 2025
By Uday Rana

It’s more than just a bad cold: influenza can also raise your risk of a heart attack shortly after an infection, medical experts are warning as the H3N2 strain spreads rapidly in Canada.

At the same time, flu season is coinciding with another risk factor for heart attacks – shovelling snow.

“Any time you get an infection, including a viral infection, there’s the release in your body of molecules that both trigger inflammation and sustain inflammation. And part of that is an increased tendency for your blood to clot,” said Dr. Fahad Razak, internal medicine physician at St. Michael’s Hospital and professor at the University of Toronto.

“That can have immediate effects within the weeks following an infection, resulting in things like strokes or heart attacks.”

Heather Hanwell’s 12-year-old daughter recently missed almost two weeks of school after being hit hard by a viral infection. She’s among many parents who are caring for sick kids this flu season, which so far has seen a surge of cases among school-age children.

But the experience was particularly frustrating for Dr. Hanwell, an epidemiologist who says that improving the air quality in schools would help reduce the spread of contagious respiratory illnesses.

The volunteer-led organization Ontario School Safety is renewing calls to the Ontario government to improve indoor air quality in schools.

The call comes as Ontario sees a rapid increase in cases of the flu, particularly impacting young children.

In April, 2021, the Government of Ontario announced it was investing over $130 million, in addition to funds from the Canadian government, to upgrade school infrastructure to protect children from COVID-19. The majority of this funding was earmarked for ventilation projects to improve indoor air quality.

At a neighbourhood Christmas party in Ottawa earlier this month, there were all the usual holiday delights: festive decor, treats and even a visit from the big man up North. It was an evening to remember for Christine Guptill, but not in the way she had imagined.

Tucked into a party room at Royale Ranch, a horse farm in the city’s south, there were nearly 40 people at the party – half children, half adults. Ms. Guptill said some children were coughing and she overheard one family say they had left their sick kid at home.

The Latest

Data from the Public Health Agency of Canada released today shows the number of flu outbreaks across the country is still rising, and hospitalizations due to the virus are set to surge in the coming weeks.
Health officials across the country are reporting a surge in cases of influenza this month, especially among children and youth.
There’s particular concern about low vaccination uptake this winter, with many provinces reporting only around 20 per cent of eligible residents have received the flu vaccine.
This year’s available vaccine isn’t a good match for the current predominant strain, H3N2 — but doctors are urging people to get their shots regardless.
