Air quality in Toronto among worst in the world amid wildfire smoke, global tracker shows

Toronto is currently the second most polluted major city in the world as wildfire smoke spreads across the city, according to a global tracker.

The ranking by IQAir, a Swiss air quality technology company, puts the city below Santiago, Chile, and above Montreal, which is in third place as it also faces wildfire smoke from western provinces.

As of noon Friday, air quality in Toronto was above 10 on Environment Canada’s air quality health index, which means “very high risk,” according to the weather agency’s website.

A warning from Canadian eye doctors about wildfires and smoke

TORONTO — The Canadian Ophthalmological Society is urging people to take care of their eyes as wildfires burn across Manitoba and Saskatchewan.

People on the frontlines of the fires may get airborne particles in their eyes that need to be flushed out with sterile solution, said Dr. David Plemel, an eye surgeon in London, Ont., who was speaking on behalf of the society.

If it’s not easy to get the particle out, he recommends seeing an eye professional so they can remove it without damaging the cornea.

Smoke travels long distances and can affect people’s eyes even if they are far away from an actual blaze, said Plemel, who is also an assistant professor of ophthalmology at Western University.

Special air quality statement in effect for eastern Ontario, western Quebec

A special air quality statement is in effect for eastern Ontario and western Quebec.

The statement was issued by Environment Canada Thursday, saying smoke caused by wildfires is expected to cause poor air quality and reduced visibility over the area tonight into Friday morning — the health risk will be high at these times.

“As smoke levels increase, health risks increase. Limit time outdoors. Consider reducing or rescheduling outdoor sports, activities and events,” reads the statement.

“You may experience mild and common symptoms such as eye, nose and throat irritation, headaches or a mild cough. More serious but less common symptoms include wheezing, chest pains or severe cough. If you think you are having a medical emergency, seek immediate medical assistance.”

The air quality statement extends as far west as Lake Huron, south into Toronto and Windsor, and north of Gatineau, Que.

Ontario confirms death of infant infected with measles

An infant in southwestern Ontario who contracted measles from their mother before birth and was born prematurely has died, Ontario’s chief medical officer of health says.

The child’s mother had not been vaccinated against the viral illness, Dr. Kieran Moore said in his statement.

While measles can be fatal, especially for young children, Moore noted the child also faced other “serious medical complications.”

“While measles may have been a contributing factor in both the premature birth and death, the infant also faced other serious medical complications unrelated to the virus,” Moore said.

Exclusive: CDC expert resigns from COVID vaccines advisory role, sources say

Pediatric infectious disease expert Dr. Lakshmi Panagiotakopoulos of the U.S. CDC resigned on Tuesday as co-leader of a working group that advises outside experts on COVID-19 vaccines and is leaving the agency, two sources familiar with the move told Reuters.

Panagiotakopoulos said in an email to work group colleagues that her decision to step down was based on the belief she is “no longer able to help the most vulnerable members” of the U.S. population.

In her role at the Centers for Disease Control and Prevention’s working group of the Advisory Committee on Immunization Practices, she co-led the gathering of information on topics for presentation.

Her resignation comes one week after Health Secretary Robert F. Kennedy Jr., a long-time vaccine skeptic who oversees the CDC, the Food and Drug Administration and the National Institutes of Health, said the COVID vaccine for healthy children and healthy pregnant women had been removed from the CDC’s recommended immunization schedule.

Federal government to match Red Cross donations to help wildfire victims

The federal government says it will match donations made to the Canadian Red Cross as wildfires tear across the Prairies, forcing thousands from their homes.

Speaking on Parliament Hill Tuesday, Emergency Management Minister Eleanor Olszewski said the money will go toward wildfire relief and disaster recovery.

The provinces of Saskatchewan and Manitoba will also match donations, she said.

RFK Jr.’s stance on Covid vaccines for pregnant women is profoundly unethical

Health and Human Services Secretary Robert Kennedy’s proposal to end the government’s existing Covid vaccine recommendation for healthy pregnant women, if enacted, will be a major setback to decades’ worth of efforts to advance the health of pregnant people and their babies.

It also profoundly unethical.

Pregnant people are consistently left behind in biomedical R&D in ways that are deeply harmful to the health of both mother and child. In the decade before the Covid pandemic, consensus reports emerged denouncing this pregnancy evidence gap and providing road maps for how to ethically generate evidence during pregnancy within the confines of existing research regulations. I co-led one of these efforts, the PREVENT project, initiated in response to the Zika epidemic and completed in fall 2019. PREVENT specifically focused on how to ethically include pregnant women in the development and deployment of new vaccines for emerging pandemic threats.

Cancelling funding for mRNA vaccine is both risky and foolish

With Donald Trump’s second administration, disruptive news seems to arise on a daily basis. Most concerning for clinicians and health scientists in Canada and around the world was Trump’s appointment of anti-vaccination zealot Robert Kennedy Jr. to the enormously influential position of Secretary of Health and Human Services. Kennedy’s ideological dismantling of the U.S.’s vaunted health research apparatus has been at speeds surprising even to his most ardent critics.

But his recent decision to cancel a nearly $600-million contract with vaccine manufacturer Moderna might be among his most shortsighted and destructive moves, with ripple effects globally.

The contract with the mRNA pioneer, signed under the Joe Biden administration, was meant to fund the development, testing and licensing of vaccines targeting particular flu strains, including the strain responsible for the dreaded avian flu, H5N1. Many scientists fear that H5N1 could become the next world-stopping infectious disease pandemic.

Much of Manitoba under air quality warnings as wildfires rage

Air quality warnings have been issued for a large swath of Manitoba, though rain could bring some much-needed relief.

Environment and Climate Change Canada (ECCC) upgraded a number of air quality statements to warnings Monday morning in a large portion of southern Manitoba, including Winnipeg, Steinbach, and Lac du Bonnet.

These areas join much of northern Manitoba, which have been under air quality warnings for days due to wildfires burning in the region and in northern Saskatchewan.

However, the weather agency notes smoke will improve with rain forecast through southern Manitoba on Monday, while northern communities under wildfire threat will likely have to wait until the weekend for precipitation.

COVID-19 Disease Burden Remains Greater Than Influenza, Study Shows

Researchers in Denmark conducted a large-scale evaluation of the disease burdens associated with COVID-19 and influenza. Their conclusion? COVID-19 has a greater impact than influenza, resulting in more hospitalizations and deaths. These findings, they note, emphasize the continued need for a strong public health response.

COVID-19 Exhibits Greater Disease Burden Than Influenza

To compare the disease burden of COVID-19 and influenza, the researchers evaluated data available from Danish health registries from May 16, 2022 to June 7, 2024. The results were published in The Lancet Infectious Diseases. A commentary about the findings was published in the same issue of the journal.

During this period, the risk of hospitalization due to COVID-19 was approximately two times higher than the risk of hospitalization due to influenza. The risk of death was approximately three times higher. The researchers note that these increased risks were greater during the first year of the study period but still were evident during the second year. The risk of mortality, for example, was five times greater for COVID-19 during the first year of the study. That increased risk dropped during the second year, but COVID-19 still had a two and a half times greater risk of mortality than influenza.

‘Very high risk’ air quality in Brandon, as smoke persists

The Air Quality Health Index (AQHI) for Brandon reached 10+, indicating a “very high risk” level on Saturday morning, as thick smoke was expected to linger in the air until Saturday night.

Environment Canada’s forecast anticipates that these hazardous conditions will persist through Saturday night, with only a slight improvement expected, dropping to a “moderate risk” (AQHI 6) by Sunday morning and a “high risk” (AQHI 7) by Sunday night.

The elevated readings are the result of thick wildfire smoke that drifted into Brandon Friday evening and remains heavy over the city Saturday morning. The smoke originates from wildfires burning in northern Manitoba and northern Saskatchewan and has led Environment Canada to issue a special air quality statement for the city.

FDA approves a next-generation Covid vaccine from Moderna, with restrictions

The Food and Drug Administration approved Moderna’s new Covid-19 vaccine late Friday, though it placed restrictions on its use that the company’s existing Covid shot, Spikevax, does not currently face.

The new vaccine, which will be marketed under the name mNexspike, will not immediately replace Spikevax. A statement from the company said both vaccines will be available on the market for the time being.

“The FDA approval of our third product, mNEXSPIKE, adds an important new tool to help protect people at high risk of severe disease from Covid-19,” Moderna CEO Stéphane Bancel said in the statement. “Covid-19 remains a serious public health threat, with more than 47,000 Americans dying from the virus last year alone.”

Wildfire smoke descends on Saskatoon

Saskatoon was under an air quality advisory Friday morning, as wildfires raging in northern Alberta and Saskatchewan sent smoke across the southern parts of the province.

Those who left a window open overnight likely woke up to the familiar smell of a campfire, but Environment and Climate Change Canada (ECCC) is advising residents to close their windows and limit strenuous outdoor activities or exercise while the system of air pollution passes through.

“Protect your indoor air from wildfire smoke. Actions can include using a clean, good quality air filter in your ventilation system and/or a certified portable air cleaner that can filter fine particles,” the statement said.

‘Make America Healthy Again’ report updated to remove nonexistent studies

The White House downplayed questions about its flagship report on children’s health, but edited the document Thursday after authors listed in the paper confirmed it cited studies that do not exist.

The highly anticipated “Make America Healthy Again” (MAHA) report was released on May 22 by Health Secretary Robert F. Kennedy Jr. and the presidential commission tasked with assessing drivers of childhood chronic disease.

But authors and publishers of at least four studies listed in the original document told AFP they or their organizations were credited with papers they did not write — or that never existed.

New COVID strain found in Montreal wastewater: health ministry

SARS-CoV-2, the virus that causes COVID-19, has mutated into two new variants that are circulating across Asia, Europe and North America, and Quebec’s public health authority warns one of the strains was detected in Montreal wastewater data.

The variant found in Quebec, XFG, has also been detected in wastewater in other parts of Canada, the United States, and Europe. Another new strain, NB.1.8.1, is associated with a rise in COVID cases and hospitalizations in China, Hong Kong, India, Taiwan, Thailand, and Singapore, according to Marie-Pierre Blier, a spokesperson from the health ministry.

Although XFG has made its way to Quebec, public health authorities assure there is no need to panic. Blier wrote in an email that it hasn’t markedly impacted public health, adding that the ministry continues to monitor the situation closely.

Almost 70 per cent of Canadians surveyed want child vaccines to be mandatory: poll

A new poll suggests nearly 70 per cent of Canadians support mandatory childhood vaccinations, but at least one public health official says she’s uncomfortable with the idea of forcing parents to immunize their kids.

The Angus Reid Institute survey landed Thursday as Public Health Ontario said 93 new measles cases have emerged in the province over the past week, bringing the total number of infections there to 1,888 since October.

The poll found 69 per cent of respondents said proof of immunization should be required for kids to attend daycare and school. That’s an increase from the 55 per cent of respondents who said the same thing last year, before a measles outbreak emerged in multiple provinces and infected mostly unvaccinated infants, kids and teens.

Loss Of MRNA, Bird Flu Vaccines Threatens Our Biosecurity

The Department of Health and Human Services announced Thursday that it’s canceling a $760 million contract with Moderna for a bird flu vaccine, saying that further development “was not scientifically or ethically justifiable.” The cancellation comes after Moderna received positive interim data from a trial testing the safety and immunogenicity of its H5N1 bird flu vaccine candidate. The fact that the Biden administration had approved the contract with Moderna did not help.

This administration’s distrust of mRNA vaccines has been apparent. In February, Rep. Adam Schiff stated that HHS Secretary Robert F. Kennedy Jr., “promoted the lie that mRNA vaccines alter human DNA.” Kennedy has previously called mRNA COVID-19 vaccinations dangerous. Further, at least seven states have proposed GOP-sponsored legislation banning or limiting mRNA vaccines and fueling mistrust in vaccines.
