Ontario School Safety Calls on Province for an Immediate Vaccine-PLUS Strategy to Tackle Current Measles Outbreak

Toronto, Ontario – [April 24, 2025] – In an urgent appeal to protect the health and safety of Ontario’s students, education workers, and families, Ontario School Safety (OSS) has issued an open letter asking the Ontario Provincial Government and Public Health Ontario for an immediate vaccine-PLUS strategy, which includes the essential role of healthy indoor air, to curtail the spread of measles. This critical request comes in the wake of concerning measles infection rates – as of April 17th, 2025, Public Health Ontario is reporting 925 measles cases in the province, more than five times the number of cases than the total number of cases over the last 12 years. Encouraging a vaccine-only strategy is insufficient due to barriers to access, and because measles spreads not only through direct contact with secretions or contaminated surfaces, but through the air we breathe.

I traded my U.S. medical career for life in Canada. Here’s how the two health systems stack up.

After more than a decade practicing emergency medicine in the United States, I very recently began working shifts in Canada. The differences hit me immediately, and are profound.

What follows are a series of working hypotheses — early impressions shaped by firsthand experience and years of health policy work in the U.S. I expect they will evolve with time, but they already point to important contrasts in how both countries approach medicine, physician autonomy, and the doctor-patient relationship.

Smartwatch Data: Study Finds Early Health Differences in Long COVID Patients

People who later experienced persistent shortness of breath or fatigue after a COVID infection were already taking significantly fewer steps per day and had a higher resting heart rate before contracting the virus, according to a CSH study published in npj Digital Medicine. This may indicate lower fitness levels or pre-existing conditions as potential risk factors

Between April 2020 and December 2022, over 535,000 people in Germany downloaded and activated the Corona Data Donation App (CDA). Of these, more than 120,000 voluntarily shared daily data from their smartwatches and fitness trackers with researchers, providing insights into vital functions such as resting heart rate and step count.

“These high-resolution data served as the starting point for our study,” explains CSH researcher Katharina Ledebur. “We were able to compare vital signs in 15-minute intervals before, during, and after a SARS-CoV-2 infection.”

BC’s Measles Vaccination Rate Is Lower Than in Gaines County, Texas

In Gaines County, Texas, where a measles outbreak has killed one six-year-old and one adult, the measles vaccination rate among kindergarteners is just 82 per cent, according to reporting by The Atlantic.

That’s a higher measles vaccination rate than children have here in B.C.

Just under 82 per cent of two-year-olds have gotten one dose of the measles, mumps and rubella, or MMR, vaccine, and around 72 per cent of seven-year-olds have gotten both doses, according to the B.C. Childhood Immunization Coverage Dashboard’s 2023 data, which is the most recent data year available.

Everything Wrong with Canada’s Proposed Long COVID Recommendations

Researchers involved in the organizations Cochrane Canada and the McMaster GRADE Centre at McMaster University are developing guidelines to prevent and treat Long COVID in Canada. Their effort is supported by the Public Health Agency of Canada and their recommendations would likely have major sway in the way Long COVID is treated if adopted.

Every month, they release new recommendations and provide an opportunity for public comment. On November 20th, the group released a new set of Canadian Post-COVID Condition (CAN-PCC) recommendations which propose harmful and ineffective treatments: Exercise to prevent Long COVID and cognitive behavioral therapy (CBT) to treat post-exertional malaise (PEM).

The Risks of Killing a COVID Early Warning System

COVID-19 is surging in parts of North America and Europe, and even played a role in ending the presidential campaign of 81-year-old Joe Biden, who was infected for the third time last month.

Nevertheless, on Wednesday the Ontario government shut down its early warning system to detect COVID and other emerging diseases.

Doctors, citizens and researchers are calling the decision to kill the province’s wastewater disease surveillance program both wrong-headed and dangerous. Ending the program will make it harder to track and thwart viral outbreaks, they say, and thereby increase the burden on Ontario’s understaffed hospitals, which experienced more than 1,000 emergency room closures last year.

“Pandemics do not end because science has been muzzled,” Dr. Iris Gorfinkel, a well-known Toronto physician and clinical researcher, told the CBC.

In emails to politicians, more than 5,000 citizens have demanded restoration of the program, with little effect.

Study: Infection-control measures stemmed COVID spread in hospitals from 2020 to 2022

Implementation of ventilation standards of at least five clean-air changes per hour, COVID-19 testing, the use of personal protective equipment (PPE), and universal wearing of respirators prevented most SARS-CoV-2 transmissions in a California healthcare system from 2020 to 2022, suggests a study published yesterday in Clinical Infectious Diseases.

For the study, University of California (UC) researchers used electronic health records and movement data of patients and staff to conduct viral genomic and social network analyses to estimate COVID-19 spread in the UC–San Diego Health system. The team analyzed 12,933 viral genomes from 35,666 infected patients and healthcare workers (HCWs) (out of 1,303,622 tests [2.7%]) from November 2020 to January 2022.

Ten COVID Facts Health Officials Dangerously Downplay

Do not listen to powers that be who pretend that getting infected with COVID multiple times is now no big deal. They’re asking you to lower your guard for a nasty virus that can invade the brain, disregulate the immune system and damage the vascular system.

This strategy has led to predictable results — more direct deaths, more excess deaths, more disease and some 1.4 million Canadians reporting some form of long COVID over the last two years.

‘Distracting the public’: group of health professionals call for RFK Jr to be removed

A grassroots organization of health professionals have released a report outlining major health challenges in the US and calling for the removal of Robert F Kennedy Jr from the US Department of Health and Human Services (HHS).

The report from Defend Public Health, a new organization of about 3,000 health professionals and allies, is an attempt to get ahead of misinformation and lack of information from health officials.

In an effort to keep making progress in public health, Defend Public Health’s report was slated to coincide with that of the anticipated second US report to “make America healthy again” (Maha). The first Maha report was released in May, and a second report was expected this week – but amid turmoil at the health agencies, it has reportedly been delayed for several weeks.

Funding Changes Might Leave BC’s Long-COVID Patients in the Lurch

Upcoming changes to B.C.’s Medical Services Plan could affect how thousands of long-COVID patients access care.

Starting Sept. 1, MSP is capping all online group medical visits to just 20 patients, to “ensure there can still be a one-on-one interaction between each patient and the attending physician,” the Health Ministry told The Tyee.

Most long-COVID care in B.C. is currently delivered through large online group telehealth sessions from the Bowen Island-based BC Centre for Long COVID, ME/CFS, and Fibromyalgia, or BC-CLMF, which currently has over 5,200 patients — with 25 more referred every day, Dr. Ric Arseneau told The Tyee.

Lab-made sugar-coated particle blocks Covid-19 infection — Possible new treatment on the horizon

Groundbreaking research led by a Swansea University academic has revealed a synthetic glycosystem — a sugar-coated polymer nanoparticle — that can block Covid-19 from infecting human cells, reducing infection rates by nearly 99%.

The glycosystem is a specially designed particle that mimics natural sugars found on human cells. These sugars, known as polysialosides, are made of repeating units of sialic acid — structures that viruses often target to begin infection. By copying this structure, the synthetic molecule acts as a decoy, binding to the virus’s spike protein and preventing it from attaching to real cells.

Unlike vaccines, which trigger immune responses, this molecule acts as a physical shield, offering a novel approach to infection prevention.

RFK Jr.’s war on mRNA vaccines breeds distrust, threatens Canada’s access to development: experts

TORONTO – Canadian doctors and scientists say Robert F. Kennedy Jr.’s defunding of mRNA vaccine research and development projects will have negative health effects in Canada and around the world.

“I think that Canadians do need to understand that this and a lot of the changes that Kennedy is making to vaccination policy in particular are definitely going to affect Canadians,” said Angela Rasmussen, a virologist at the University of Saskatchewan’s Vaccine and Infectious Disease Organization.

Unlike other vaccines, mRNA vaccines can be made very quickly. They can also be easily modified to fight new viruses and adapt to changing strains — something that we saw as new variants emerged during the COVID-19 pandemic, Rasmussen said.

HHS scraps further work on life-saving mRNA vaccine platform

In what experts say will hobble pandemic preparedness, US Health and Human Services (HHS) Secretary Robert F. Kennedy Jr. yesterday announced the dismantling of the country’s mRNA vaccine-development programs—the same innovation that allowed rapid scale-up of COVID-19 vaccines during the public health emergency.

The Biomedical Advanced Research and Development Authority (BARDA) is terminating 22 mRNA vaccine-development contracts totaling just under $500 million, including an award to Moderna/University of Texas Medical Branch for a vaccine against the H5N1 avian flu now sweeping the world. That grant was terminated in late May.

Contracts awarded to Emory University and Tiba Biotech were cancelled, and agreements with Luminary Labs, ModeX, and Seqirus have been scaled back.

Canada likely to lose measles elimination status as outbreak continues: expert

Canada is at risk of losing its measles elimination status as an outbreak that started in New Brunswick last year continues to grow.

Measles has been considered eliminated in Canada since 1998, and the country saw an average of 91 cases annually before October 2024, when the outbreak began. The designation means that, within a certain geographical region, there has been no sustained measles transmission over 12 consecutive months.

Since then, of the 4,394 measles infections nationwide, Health Canada data shows that most individuals were exposed to the virus domestically (94 per cent) and were not vaccinated (88 per cent).

RFK Jr. pulls $500 million in funding for vaccine development

WASHINGTON (AP) — The Department of Health and Human Services will cancel contracts and pull funding for some vaccines that are being developed to fight respiratory viruses like COVID-19 and the flu.

Robert F. Kennedy Jr. announced in a statement Tuesday that 22 projects, totaling $500 million, to develop vaccines using mRNA technology will be halted.

Kennedy’s decision to terminate the projects is the latest in a string of decisions that have put the longtime vaccine critic’s doubts about shots into full effect at the nation’s health department. Kennedy has pulled back recommendations around the COVID-19 shots, fired the panel that makes vaccine recommendations, and refused to offer a vigorous endorsement of vaccinations as a measles outbreak worsened.

Alberta’s Perverse New Barriers to COVID Vaccines

Alberta Premier Danielle Smith’s radical new rules for COVID immunization pose a genuine threat to the elderly, the working poor and pregnant moms.

Smith, who revived her ailing political career by peddling conspiratorial COVID theories, has designed a program that is not only punitive but discriminatory, bureaucratic and Soviet in nature.

“This policy is so bad that it’s actually worse than their usual failure to plan properly,” said James Talbot, the province’s former chief medical officer of health. “In fact, it is so bad it looks like they are actually planning to fail.”

Here are the three basic tenets of any successful public health program: make it available, make it accessible and make it affordable. Smith turns all three upside down.

Bird Flu May Be Airborne on Dairy Farms, Scientists Report

The bird flu virus that has beset dairy farms since early last year may be spreading through the air in so-called milking parlors and through contaminated wastewater, as well as from milking equipment, scientists have found.

The Department of Agriculture has said that the virus spreads primarily from milking equipment or is carried by dairy workers and vehicles traveling between farms.

But in the new study, scientists found live virus in the air of milking facilities, suggesting that cows and farmworkers might have become infected by inhaling the pathogen. The virus may also spread by water used to clean cattle barns or contaminated with discarded milk.

Analysis: 2024-25 COVID vaccines offered strong protection against worst outcomes in seniors

The 2024-25 COVID mRNA vaccines targeting JN.1 were highly effective in protecting against hospitalization and death for at least 4 months in a cohort of Danish citizens aged 65 and older by October 1, 2024. The new analysis estimating the vaccine efficacy (VE) of last season’s COVID vaccines was published earlier this week in The Lancet Infectious Diseases.

In total, 894,560 Danish residents were included in the study, with a median age of 76. By Jan 31, 2025, 820,229 (91.7%) of the participants had received a JN.1 vaccine. Among those without updated JN.1 vaccination (74,331), 278 COVID-19 hospitalizations and 84 deaths were observed during 25.6 million person-days.

Biological causes of long COVID discovered: the virus persists for months in the brain

Long COVID, often attributed to a psychosomatic mechanism, has biological causes, a study reveals. Months after the infection, the virus was still active, at low levels, in the brainstem of hamsters.

“We hope to bring relief to the patients who may have heard that they are not sick, that it is ‘in their heads.’ What we are showing in the laboratory is that long COVID has a biological cause!,” says Guilherme Dias de Melo, a veterinarian and researcher in infectious diseases and neuropathologies at the Institut Pasteur. Eighty days after the initial infection, the COVID-19 virus was found, still infectious, in the brainstems of hamsters affected by symptoms similar to those of long COVID, according to the work that he has directed and published in the journal Nature Communications.

COVID infection early in pandemic linked to higher risk of cancer death, CU study finds

Cancer survivors infected with COVID-19 in the early months of the pandemic had a higher risk of dying from dormant cells reawakening, Colorado researchers found, though they don’t know whether people who get the virus now face the same risk.

Experiments in mice found that genetically modified animals were more likely to have signs of metastatic cancer in their lungs if infected with flu or COVID-19 than engineered mice that researchers didn’t give a virus, said James DeGregori, deputy director of the University of Colorado Cancer Center in Aurora.

That finding launched an international partnership to determine whether the same thing happened in people, he said.

‘Sleeping’ cancer cells in the lungs can be roused by COVID and flu

Hidden in the lungs of some breast cancer survivors are tumour cells that can remain dormant for decades — until they one day trigger a relapse. Now, experiments in mice show that these rogue cells can be roused from their slumber by common respiratory illnesses such as COVID-19 or the flu.

The findings, published in Nature on 30 July1, seem to extend to humans too: data from thousands of people show that infection with the coronavirus SARS-CoV-2 is linked with a nearly twofold increase in cancer-related death, possibly helping to explain why cancer death rates increased early during the COVID-19 pandemic.

B.C. plans to cut payments for long-COVID clinics, leaving patients in lurch

A virtual clinic that treats patients for long COVID and other chronic conditions is warning that it may have to partially shut down if the province goes ahead with changes on Sept. 1 that would limit the number of patients who can take part in online group appointments.
