A study published earlier this week in Nature Communications using claims data from the US Veterans Affairs (VA) Healthcare System finds protection from the 2024-25 Pfizer COVID-19 vaccine was 68%, 57%, and 56% against COVID-19–associated hospitalizations, emergency department and urgent care (ED/UC) visits, and outpatient visits, respectively.

However, the authors caution that uptake of the vaccine was extremely low—only 3.7% through November 2024—and the study did not assess waning effectiveness.

The study estimated early BNT162b2 KP.2 (2024-25 formulation) vaccine effectiveness (VE) against COVID-19 outcomes compared to not receiving the vaccine.

📣 Let municipal councillors know you want funding for wastewater monitoring to continue

✉️ Send letters to municipal councillors in Ottawa to voice your support for wastewater monitoring. Use our online tool to send emails.

Why take action? The funding for Ottawa’s wastewater monitoring program is currently set to expire in September 2025. Wastewater monitoring is an essential public health tool that provides insights into the spread of SARS-CoV-2 and other viruses in Ottawa. We need an early warning system to inform everyone about the prevalence of SARS-CoV-2 subvariants, influenza, avian flu, RSV, mpox, and other viruses.

Possible treatments for long COVID at the centre of new Western study

More than 300 patients across four continents are at the centre of a Western long COVID study, which hopes to find an effective treatment for those who struggle with long COVID.

The study will look to trial two anti-inflammatory medicines as potential treatments, and hopes to bring into view people who struggle with the disease outside of North America.

“Despite the global prevalence of long COVID, patients report different symptoms and their presentation can be influenced by where they happen to live,” said Dr. Douglas Fraser, professor at Western’s Schulich School of Medicine & Dentistry. “A study with global reach, tailored to examine each patient’s most severe symptoms, has the potential to bring hope to people well beyond Canada and the U.S.”

HHS Secretary Robert F. Kennedy Jr. is weighing pulling the Covid-19 vaccine from the government’s list of recommended immunizations for children, two people familiar with the discussions told POLITICO.

The directive under consideration would remove the Covid shot from the childhood vaccine schedule maintained by the Centers for Disease Control and Prevention and widely used by physicians to guide vaccine distribution, marking Kennedy’s most significant move yet to shake up the nation’s vaccination practices.

Is Public Health Really Dead?

By Michelle Gamage

Local podcaster Daniella Barreto called her latest project Public Health Is Dead to capture her frustration with how leaders handled the COVID-19 pandemic.

“It seemed like all of these things we’re taught in school, like prevention being key and using evidence to make decisions, was thrown out the window,” Barreto told The Tyee. “Mask mandates were being taken away, people were increasingly getting long COVID, and I decided I needed to do something because people were not getting the information they needed.”

Launching the podcast in November 2024, Barreto used her background in public health, with a master of science in population public health from the University of British Columbia and a bachelor of science in health science from Simon Fraser University, to help explain what went wrong. So far she’s released five episodes and has many more in the works.

Manitoba is rolling out a vaccination campaign for those at the highest risk of developing serious outcomes from COVID-19, aiming to get people vaccinated before summer, when virus circulation might increase, the province says.

The extra doses will be available to anyone age 65 or older, Indigenous people over the age of 45, residents of long-term care homes, and anyone age six months or up who is moderately or severely immunocompromised.

Countries united under the World Health Organization on Wednesday agreed to a milestone accord on how to respond to future pandemics and avoid repeating the mistakes made during the Covid-19 crisis. The agreement comes despite US foreign aid cuts and possible tariffs on pharmaceuticals casting uncertainty over the talks.

Years of negotiations culminated early Wednesday with countries agreeing the text of a landmark accord on how to tackle future pandemics, aimed at avoiding a repeat of the mistakes made during the Covid-19 crisis.

After more than three years of talks and one last marathon session, weary delegates at the World Health Organization’s headquarters sealed the deal at around 2am (0000 GMT) Wednesday.

“Tonight marks a significant milestone in our shared journey towards a safer world,” WHO chief Tedros Adhanom Ghebreyesus said.

“The nations of the world made history in Geneva today.”

(Montreal) A COVID-19 vaccination campaign is launched this spring for people at risk of developing complications, Santé Québec announced on Monday.

Teams are currently deployed in the province’s long-term care homes, after which vaccination will be offered in private seniors’ residences (RPA) with a more vulnerable clientele.

In addition to CHSLDs and RPAs, seniors 75 years of age or older and people with immunodeficiency or dialysis are encouraged to go get their vaccine dose. This vaccination campaign also aims to reach people aged 65-74 who live with a chronic disease or in remote and isolated areas.

Non-targeted people aged 6 months and older can also receive the COVID-19 vaccine free of charge, says Santé Québec. If they have already been vaccinated, they should wait at least six months after their vaccine before receiving a new dose.

Nearly 1 in 7 working-age US adults had experienced long COVID by late 2023, and socially disadvantaged adults were over 150% more likely to have persistent symptoms, two new studies find.

Future public health, economic burdens

Yesterday in Communications Medicine, Daniel Kim, MD, DrPH, of Northeastern University, analyzed data from the US Census Bureau’s Household Pulse Survey from September and November 2022 and August to October 2023 on more than 375,000 US adults, including nearly 50,000 with self-reported long COVID.

Kim assessed sociodemographic and socioeconomic factors as predictors of long COVID; estimated the risk of unemployment, financial difficulties, and anxiety and depression among working-age adults (ages 18 to 64 years) and those currently experiencing lingering symptoms; and tallied the economic effects of the resulting lost wages.

The world-first study found mice treated with the antiviral compound, developed by a multidisciplinary research team at WEHI, were protected from long term brain and lung dysfunction – key symptoms of long COVID.

Researchers hope the unprecedented results could lead to clinical trials and the first treatment for the disease in the future.

Stuffy, crowded classrooms mean kids are breathing in viruses and pollution. Parents are trying to make the air safer, but hitting roadblocks.

In September 2023, Heather Pun started sending her son to school with a carbon dioxide monitor. He was spending his days in a stuffy portable classroom, and she worried that COVID was being passed lung-to-lung through the stale air.

The device, which reads the concentration of carbon dioxide (CO2) in the air, showed CO2 levels as high as 3,500 parts per million (ppm) in his classroom.

According to a recent BC Ministry of Health release, “People are still encouraged to wear medical masks in health care settings as appropriate,” but it is not mandatory.

Some groups, including Protect Our Province BC and DoNoHarm BC, are questioning the decision. This response comes after B.C. announced that it was launching the spring immunization campaign on April 8.

COVID-19 boosters help avoid breakthrough infections in immunocompromised people, McGill-led study finds

Published March 31, 2025

Published by: McGill University
Published on: March 31, 2025

Researchers focused on those with rheumatoid arthritis, lupus, inflammatory bowel disease, multiple sclerosis and other immune-mediated inflammatory diseases

New research findings provide solid evidence that annual COVID-19 vaccine booster doses continue to be advisable for certain immunocompromised people, researchers at McGill University say.

The researchers looked at how often people with immune-mediated inflammatory diseases (IMIDs) got COVID-19 despite having received at least three doses of an mRNA COVID-19 vaccine. IMIDs – including rheumatoid arthritis, lupus, inflammatory bowel disease and multiple sclerosis – affect more than seven million Canadians. The medications they take often weaken their vaccine responses, increasing their vulnerability to infection.
