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.”

German Health Minister Nina Warken has rejected accusations by US Health Secretary Robert F Kennedy Jr that doctors in Germany have faced legal action for issuing vaccine and mask exemptions during the coronavirus pandemic.

Kennedy, a known vaccine skeptic, posted a video on X on Saturday in which he says: “I’ve learned that more than a thousand German physicians, and thousands of their patients, now face prosecution and punishment for issuing exemptions from wearing masks or getting COVID-19 vaccines during the pandemic.”

Face masks ‘inadequate’ and should be swapped for respirators, WHO is advised

Experts are urging guideline changes on what health professionals should wear to protect against flu-like illnesses including Covid

Surgical face masks provide inadequate protection against flu-like illnesses including Covid, and should be replaced by respirator-level masks – worn every time doctors and nurses are face to face with a patient, according to a group of experts urging changes to World Health Organization guidelines.

There is “no rational justification remaining for prioritising or using” the surgical masks that are ubiquitous in hospitals and clinics globally, given their “inadequate protection against airborne pathogens”, they said in a letter to WHO chief Dr Tedros Adhanom Ghebreyesus.

“There is even less justification for allowing healthcare workers to wear no face covering at all,” they said.

In utero SARS-CoV-2 exposure may predispose children to altered brain volumes, impaired cognition, and internalizing emotional problems such as anxiety and depression, researchers from Children’s National Hospital and George Washington University write in Brain, Behavior, and Immunity.

The team enrolled 39 mother-baby pairs in Washington, DC, who had been exposed to COVID-19 during pregnancy from 2020 to 2022 and compared them with 103 normative pairs from before the pandemic (2016 to 2019). None of the infected women had been vaccinated against SARS-CoV-2.

COVID-19 Is Six Today. What We’ve Learned

We need cleaner air, which requires changes in medical culture.

Last year on this date, I published a Tyee article about the fifth anniversary of the first public announcement of what we now know as COVID-19.

My conclusions then were that we hadn’t learned much from the experience. A year later, many of us have unlearned the value of vaccination. Outbreaks of measles and whooping cough have predictably followed. Alberta has stopped reporting COVID-19 in hospitals.

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

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.

Work-related factors may increase the risk of developing long COVID, according to a new population-based study from Spain.

The findings, published in BMJ Occupational & Environmental Medicine, suggest that the primary work-related drivers of increased long COVID risk were irregular or limited use of respirators, close contact with coworkers and/or the public, inability to physical distance, and use of public transportation to commute to work.

Alberta’s government quietly eliminated its public reporting dashboard of COVID-19 outbreaks in acute care facilities, saying the province is under no legal obligation to continue publishing the data in a “post-pandemic context.”

Alberta Health Services’ (AHS) acute-care outbreaks webpage provided weekly public reports on COVID-19 outbreaks in AHS and Covenant Health facilities, including the location where an outbreak had been reported, the date the outbreak was declared, the number of units affected, and how many patients and health-care workers were infected.

TORONTO – A new poll says that about three-quarters of Canadian adults still have confidence in vaccines, but hesitancy has increased over the last five years.

The survey conducted by Leger Healthcare and released on Tuesday says 74 per cent of respondents said they were either “very confident” (42 per cent) or “somewhat confident” (32 per cent) in the safety and effectiveness of vaccines.

But about a quarter of respondents said they are less confident than they were before.

Occupational Factors Strongly Influence Long-COVID Risk

A large Catalan cohort study shows that healthcare, social care, education, retail, and transport workers are at higher risk for Long-COVID

Published December 16, 2025

Published on: December 16, 2025

Work-related factors play a significant and independent role in the risk of developing Long-COVID, shows a new study based on the COVICAT cohort and led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by “la Caixa” Foundation, in collaboration with the University of Turin and the Germans Trias i Pujol Institute (IGTP). The findings, published in BMJ Occupational & Environmental Medicine, highlight that a substantial share of Long-COVID could be prevented through targeted workplace measures and policies.

The public health impact of Long-COVID is far from over. Beyond ongoing infections that continue to cause illness and deaths worldwide, millions of people are living with lasting health consequences. Globally, around 6 in every 100 COVID-19 cases develop Long-COVID, amounting to 400 million affected people and an annual economic impact of roughly 1 trillion dollars, or 1% of the global economy.

COVID-19 does not just affect the respiratory system, but also significantly alters the brain in people who have fully recovered from the infectious disease, highlighting the long-term neurological impact of the virus.

Researchers from Griffith University’s National Centre for Neuroimmunology and Emerging Disease (NCNED) used advanced MRI techniques to ascertain the neurological implications of COVID-19 compared with those who had never been infected.

The research provided compelling evidence that even in the absence of ongoing symptoms, prior infection with the virus could leave a measurable imprint on the brain.

TORONTO – A new study says the COVID-19 vaccine protects pregnant women from getting severely ill or giving birth prematurely.

Researchers with the Canadian Surveillance of COVID-19 in Pregnancy (CANCOVID-Preg) program, led by the University of British Columbia analyzed public health and clinical records of 19,899 pregnant people diagnosed with COVID between April 5, 2021 and Dec. 31, 2022.

That time period covered infections with both Delta and Omicron variants in eight provinces and one territory.

Long-COVID research just got a big funding boost: will it find new treatments?

The German government has committed half a billion euros to research into long COVID and other post-infection syndromes.

In a major boost to research on long COVID and chronic fatigue syndrome (CFS), also known as myalgic encephalomyelitis (ME), the German government has announced that it will provide €500 million (US$582 million) in research funding to support a National Decade Against Post-Infectious Diseases from 2026 to 2036.

Germany is one of many countries facing an unprecedented health burden owing to long COVID and other post-infection syndromes since the COVID-19 pandemic. Almost one in five people in a German cohort had long COVID in 2022, and around one in seven people in the United States were affected by long COVID by late 2023. This translates to a considerable burden on health care and the economy — the syndrome is estimated to cost the world economy US$1 trillion every year.

SARS-CoV-2 Leaves a Lasting Mark on the Immune System

A landmark new study shows COVID-19 isn’t ‘just a cold’: One infection left people with long-lasting immune damage, and those with heart disease lost up to 70% of key immune cells. Reinfections may worsen this. The message is clear: protecting ourselves still matters.

A new study in the International Journal of Infectious Diseases should end any lingering idea that SARS-CoV-2 is ‘just another cold virus.’ It shows that a single, relatively short Omicron wave left a long, measurable scar on the adaptive immune systems of tens of thousands of adults and that people with cardiovascular disease (CVD) may be living with something close to chronic immune compromise nearly two years later.

This isn’t about individual anecdotes, or small clinic cohorts. It’s a population-scale signal, drawn from more than 40,000 patients in a region of China that had almost no SARS-CoV-2 circulation until late 2022. It is, in many ways, the cleanest before and after picture we have of what one mass SARS-CoV-2 exposure does to human immunity.
