One in nine Canadians have experienced Long COVID symptoms, ranging from mild to debilitating. A new exhibition at the Museum of Vancouver, co-produced by Simon Fraser University’s Faculty of Health Sciences, invites visitors into the often-invisible world of those living with the life-altering effects of COVID-19.

Long COVID is a chronic condition affecting one or more organ systems that occurs after a SARS-CoV-2 infection and lingers for at least three months as a continuous, relapsing and remitting, or progressive disease state. Despite its prevalence, the condition remains widely misunderstood, under-researched, and stigmatized.

The Living with Long COVID exhibition brings these realities to light and offers a unique opportunity to intimately understand Long COVID through the eyes of those living it.

COVID-19 causes women’s blood vessels to age prematurely, according to an international study involving two researchers from Université Laval. The disease should therefore be considered an additional risk factor in cardiovascular health analyses. Specifically, in those who have developed severe symptoms, they warn.

The aging of blood vessels results in greater rigidity, which can increase the risk of certain cardiovascular diseases.

“The heart must work a little harder to propel blood through the arterial system, and this causes variations in pressure that can damage sensitive organs, including the brain and kidneys,” explains Catherine Fortier, a kinesiologist and researcher in vascular aging at the CHU de Québec-Université Laval.

Researchers use a specialized brain imaging technique to identify a potential biomarker and therapeutic target of Long COVID

Long COVID is a chronic condition that causes cognitive problems known as “brain fog,” but its biological mechanisms remain largely unclear. Now, researchers from Japan used a novel imaging technique to visualize AMPA receptors—key molecules for memory and learning—in the living brain. They discovered that higher AMPA receptor density in patients with Long COVID was closely tied to the severity of their symptoms, highlighting these molecules as potential diagnostic biomarkers and therapeutic targets.

Children and teenagers are twice as likely to develop long Covid after a second coronavirus infection as after an initial infection, a large new study has found.

The study, of nearly a half-million people under 21, published Tuesday in Lancet Infectious Diseases, provides evidence that Covid reinfections can increase the risk of long-term health consequences and contradicts the idea that being infected a second time might lead to a milder outcome, medical experts said.

Dr. Laura Malone, director of the Pediatric Post-Covid-19 Rehabilitation Clinic at Kennedy Krieger Institute in Baltimore, who was not involved in the study, said the findings echo the experience of patients in her clinic.

A US modeling study published yesterday in JAMA Pediatrics estimates that vaccinating pregnant women against COVID-19 prevented 7,000 hospitalizations in infants and 3,000 in pregnant women from January 2024 to May 2025.

The Stanford University–led research team analyzed COVID-NET surveillance data on COVID-19 hospitalization rates in infants younger than 6 months and incidence data on pregnant women aged 18 to 49 years under a relative risk of 2.65. The aim was to estimate the health impact of vaccination during pregnancy, mainly during the second or third trimester.

Grandma’s stories

The author identifies several weak points in the discourse of Quebec Public Health regarding the prevention of COVID, particularly with regard to vaccination and the spread of the virus.

Grandmother Germaine liked to tell stories. I often fell asleep next to her, lulled by the adventures of Tom Thumb. She also liked to sprinkle our days with a lot of advice, and it was only later that I realized they were also grandmother’s stories. How many times has she repeated to me: “Put your hat on, you’re going to catch a cold!” While studying medicine, I quickly understood that wearing my hat wouldn’t prevent me from catching a virus!

My grandmother passed away a long time ago, but others have taken over and in turn tell a grandmother’s stories. Take, for example, Quebec Public Health: in 2025, it continues to repeat to us to wash our hands to avoid catching COVID. While it is true that washing the hands helps prevent other infections (such as gastroenteritis), this measure is not effective in protecting oneself from COVID.

Provinces and territories are starting to roll out updated vaccines to protect people from COVID-19.

The Public Health Agency of Canada’s immunization guide says COVID vaccines have been shown to be effective at preventing severe disease, including hospitalization and death and can decrease the risk of post-COVID-19 condition, or long COVID.

The vaccination campaign comes as COVID-19 cases in people going to emergency or urgent care for respiratory symptoms have increased. About 10 per cent of tests were positive for the week ending Sept. 20, up from 9.6 per cent the previous week, according to the federal respiratory virus snapshot.

When Ontario rolls out its fall vaccination campaign at pharmacies, doctor’s offices and clinics across the province in the coming weeks, it will be bucking a trend.

At a time when both Alberta and Quebec have stopped funding COVID vaccines for the general public, limiting them to higher risk populations, and access to COVID vaccines is becoming limited in the United States, Ontario is moving in another direction.

The fall vaccination campaign, beginning in October, includes free access to an updated COVID-19 vaccine for the general public as well as expanded access to a vaccine to prevent RSV (respiratory syncytial virus) for older adults, and the flu vaccine.

WASHINGTON (AP) — President Donald Trump on Monday used the platform of the presidency to promote unproven and in some cases discredited ties between Tylenol, vaccines and autism as his administration announced a wide-ranging effort to study the causes of the complex brain disorder.

“Don’t take Tylenol,” Trump instructed pregnant women around a dozen times during the unwieldy White House news conference, also urging mothers not to give their infants the drug, known by the generic name acetaminophen. He also fueled long-debunked claims that ingredients in vaccines or timing shots close together could contribute to rising rates of autism in the U.S., without providing any medical evidence.

Moderna’s Laval plant has delivered its first doses of messenger RNA (mRNA) COVID-19 vaccines. The federal government hopes that the plant, which was built at a cost of $180 million with a $25 million investment from Quebec, will enable Canada to achieve pharmaceutical self-sufficiency.

“We will never find ourselves in this situation again,” said Minister of Innovation, Science and Industry Mélanie Joly at a press conference on Friday, recalling that Canada had to rely on the United States, the European Union, and India for its vaccine supply during the pandemic.

“We are building a strong industrial capacity, a sovereign industrial capacity, which will ensure that we are not dependent on other countries for our vaccine production.”

Starting this fall, the COVID-19 vaccine will no longer be offered free of charge to the entire Quebec population, confirmed the National Director of Public Health, Luc Boileau, on Wednesday.

Speaking on Midi info on ICI Première on Wednesday, Dr. Boileau clarified that the vaccine will be free for those deemed at risk.

This includes people aged 65 and over, the immunocompromised or those suffering from chronic illnesses, residents of CHSLDs, private seniors’ residences (RPAs) or other vulnerable settings, healthcare workers, adults living in remote areas, as well as pregnant women.

This fall, the COVID-19 vaccine will no longer be offered free of charge to the entire population, unlike in previous years. Quebec, now responsible for purchasing doses, will offer them free of charge only to those deemed at higher risk, Le Devoir has learned.

This information, which was communicated to pharmacies, was later confirmed to Le Devoir by the office of Health Minister Christian Dubé.

Quebec will therefore reserve the free doses during the vaccination campaign for people aged 65 and over, residents of CHSLDs, private seniors’ residences (RPAs), and other congregate settings with many vulnerable seniors, those who are immunocompromised or suffering from chronic illnesses, as well as pregnant women.

On June 20, the Canadian Standards Association, also known as the CSA Group, released a new draft version of CSA standard Z94.4, which was open to public consultation until August 19. It sets to regulate workplace standards around “the selection, use, and care of respirators.” The CSA Group is a non-profit organization which creates non-legally binding but precedent-setting regulations for professional workplace standards. As reported by DoNoHarm BC, the rule changes would see new nationwide respirator requirements that mandate the use of respirators like N95 masks instead of surgical masks by workers, patients, and visitors in healthcare settings.

The CSA Group’s new draft has received praise from healthcare advocates and workers alike. DoNoHarm BC was one of the leading organizations pushing the public to support and contribute to the CSA Group’s consultation process.

Viewpoint: Four tips for understanding this week’s ACIP meeting

By Vaccine Integrity Project Staff and Advisers

The last meeting of the Centers for Disease Control and Prevention’s (CDC’s) Advisory Committee on Immunization Practices (ACIP) in June abandoned the use of its rigorous evidence-to-recommendation framework for making vaccine policy decisions, which structures decisions around key factors, including the balance of benefits and harms, the type or quality of evidence and health economic analyses, among other elements. The meeting also included new members making inaccurate statements about both vaccine safety and efficacy and included a presentation by a well-known anti-vaccine advocate that was filled with errors.

Now, the committee is set to include even more vaccine skeptics when it meets later this week, according to published reports, including multiple anti–COVID mRNA vaccine activists. (On Monday, the U.S. Department of Health and Human Services (HHS) confirmed five new ACIP members.)

Relative to uninfected children, COVID-19 patients aged 8 to 17 years were at a 49% higher risk for new-onset depression or anxiety in 2021, rising to 59% in those with severe illness, according to a University of Utah study published this week in PLOS One.

The researchers mined the Utah All Payers Claims Database to explore the link between COVID-19 infection, illness severity, and risk of depression and anxiety among 154,565 school-aged youth who had private insurance or Medicaid coverage. The average participant age was 10.8 years in 2019, when the study period began, and 48% were girls.

Key contributors to mental illness among children include the pandemic’s direct impacts on daily life, such as school closures, isolation from peers, and disrupted family routines, the authors noted.
