COVID vaccines don't cause cancer. But false claims persist in sea of misinformation – CHEK News

Published

 on


Anyone who spends even a moderate amount of time online has likely come across social media posts falsely claiming that COVID-19 vaccines are harmful to human health.

Among the most widely debunked claims is that vaccines developed with messenger RNA technology can cause cancer because they contain “monkey virus DNA.”

Such claims were even repeated during a U.S. congressional hearing on vaccine injuries last year, but North American and European health authorities have stressed that there is no proof of a causal link between COVID vaccines and cancer, or that mRNA vaccines can alter human DNA in any way.

A senior policy analyst with the Canadian Cancer Society also debunked such claims while noting the added harm of false beliefs is that they can derail the deployment of proven therapies.

“Misinformation can increase vaccine hesitancy and can delay the provision of health care,” Apiramy Jeyapalan said in an emailed statement.

The fact that cancer patients and others may still be exposed to that kind of misinformation online and elsewhere is very concerning and shouldn’t be ignored by the medical and scientific community, says a Canadian scientist whose areas of expertise include health literacy.

Cheryl Peters, a senior scientist at BC Cancer and the BC Centre for Disease Control, said going through cancer treatment is “a highly vulnerable time,” especially for patients who are feeling overwhelmed and may be susceptible to information from dubious sources.

“We have to be aware that these things are circulating and be aware that our friends and family could be getting exposed to these conspiracy theories that might really actually materially harm them if they listen to them,” Peters said.

She noted that people who spread vaccine misinformation online attribute all sorts of things – from heart attacks to sudden deaths – to COVID shots. So when it comes to false claims, for example, that the vaccines are also the reason younger age groups are seeing higher rates of certain types of cancer than previously, “your Spidey senses should go up.”

“There’s no sort of one exposure to something — whether it be a vaccine or other (things) — that’s going to be able to cause every single kind of negative health outcome. That’s just not how our biology works,” Peters said.

Dr. Aaron Schimmer, director of research at the Princess Margaret Cancer Centre in Toronto, said he believes the level of misinformation surrounding COVID vaccines has decreased over time, but acknowledged that false claims still creep up.

“I think a number of patients, especially around the time when the vaccines were introduced, if they were newly diagnosed with cancer around that time … would say, ‘Well, you know, my cancer was caused by the vaccine.’ Of course, again, biologically that’s not true. Those cancers have been there probably growing slowly (over) many years,” he said.

Schimmer, who mainly treats leukemia in his clinical practice, said none of his own patients have raised specific conspiracy theories about vaccines and cancer, “but I’ve definitely had patients who’ve had concerns about the vaccine, the safety and questions as to whether the vaccine was the trigger for their cancer.”

The irony, Schimmer said, is that mRNA vaccines were being tested as potential cancer treatment long before the COVID pandemic hit. The idea is that mRNA could train an individual’s immune system to target specific cancer cells.

“It was the investments that were being made at the time to understand how these may work as cancer treatments that actually allowed us to generate a COVID vaccine so quickly,” he said.

Peters, the BC Cancer scientist, said mRNA vaccines have great value and there is promising work to be done with them in the future. But she wonders if the science behind that is being properly translated and communicated to the masses.

“That’s a bit of an existential question for science in general, I think,” she said.

Samara Perez, a clinical psychologist in the psychosocial oncology department of McGill University Health Centre in Montreal, says the vast majority of patients consider doctors and health-care professionals to be the most trusted sources of information, and research over the years has backed that up.

Even though a cancer diagnosis can set off a range of psychological responses, such as depression and anxiety, Perez does not believe a particular vulnerability to misinformation is among them.

“I think people that are susceptible to misinformation prior to (getting) cancer would be the same after,” said Perez, who is also a professor at McGill University, noting that she debunks any cancer myths raised by her patients “right away.”

Both Schimmer and Peters said there’s nothing wrong with a healthy dose of skepticism when it comes to making personal medical choices. Peters said she also understands why some patients – especially those from historically marginalized communities – distrust the system.

But that’s where doctors, scientists and health-care authorities have to step up and ensure that they are being upfront about the rare, but real, vaccine side-effects and other potential negative outcomes, she said, noting that transparency goes a long way toward building trust.

A study co-authored by Peters and published earlier this year found that Canadians were better at identifying known cancer risk factors, such as tobacco use, than recognizing cancer myths.

For example, more than half of survey respondents incorrectly believed that stress and consuming additives increases cancer risk. Between 20 and 30 per cent believed risk is increased by wearing deodorant, using hair dye, living near power lines and “having bad luck.” But the vast majority of respondents did not believe that vaccination, in general, is a risk factor.

Peters believes that myths and misinformation now play a bigger role in health-care choices people make than in the past because “we all have basically unlimited access to information” – and some people are intentionally peddling false claims online so they can profit from unproven “remedies.”

“And that, I think, is not a problem that’s going away,” Peters added. “Cancer patients and other people with chronic conditions really need support.”

The Canadian Cancer Society advises people to approach unverified sources of information with caution. On its website, the society aims to dispel some common myths – such as the belief that certain foods can prevent or cure cancer – and urges people who have questions or are unsure about something to call its cancer information helpline.

“For people with cancer, talk to your health-care team about which of the approved COVID-19 vaccines is right for you, and to determine the best timing of the doses based on your unique circumstance,” the society said in a statement.

Health Canada approves updated Moderna COVID-19 vaccine

Published

 on

 

TORONTO – Health Canada has authorized Moderna’s updated COVID-19 vaccine that protects against currently circulating variants of the virus.

The mRNA vaccine, called Spikevax, has been reformulated to target the KP.2 subvariant of Omicron.

It will replace the previous version of the vaccine that was released a year ago, which targeted the XBB.1.5 subvariant of Omicron.

Health Canada recently asked provinces and territories to get rid of their older COVID-19 vaccines to ensure the most current vaccine will be used during this fall’s respiratory virus season.

Health Canada is also reviewing two other updated COVID-19 vaccines but has not yet authorized them.

They are Pfizer’s Comirnaty, which is also an mRNA vaccine, as well as Novavax’s protein-based vaccine.

These people say they got listeria after drinking recalled plant-based milks

Published

 on

 

TORONTO – Sanniah Jabeen holds a sonogram of the unborn baby she lost after contracting listeria last December. Beneath, it says “love at first sight.”

Jabeen says she believes she and her baby were poisoned by a listeria outbreak linked to some plant-based milks and wants answers. An investigation continues into the recall declared July 8 of several Silk and Great Value plant-based beverages.

“I don’t even have the words. I’m still processing that,” Jabeen says of her loss. She was 18 weeks pregnant when she went into preterm labour.

The first infection linked to the recall was traced back to August 2023. One year later on Aug. 12, 2024, the Public Health Agency of Canada said three people had died and 20 were infected.

The number of cases is likely much higher, says Lawrence Goodridge, Canada Research Chair in foodborne pathogen dynamics at the University of Guelph: “For every person known, generally speaking, there’s typically 20 to 25 or maybe 30 people that are unknown.”

The case count has remained unchanged over the last month, but the Public Health Agency of Canada says it won’t declare the outbreak over until early October because of listeria’s 70-day incubation period and the reporting delays that accompany it.

Danone Canada’s head of communications said in an email Wednesday that the company is still investigating the “root cause” of the outbreak, which has been linked to a production line at a Pickering, Ont., packaging facility.

Pregnant people, adults over 60, and those with weakened immune systems are most at risk of becoming sick with severe listeriosis. If the infection spreads to an unborn baby, Health Canada says it can cause miscarriage, stillbirth, premature birth or life-threatening illness in a newborn.

The Canadian Press spoke to 10 people, from the parents of a toddler to an 89-year-old senior, who say they became sick with listeria after drinking from cartons of plant-based milk stamped with the recalled product code. Here’s a look at some of their experiences.

Sanniah Jabeen, 32, Toronto

Jabeen says she regularly drank Silk oat and almond milk in smoothies while pregnant, and began vomiting seven times a day and shivering at night in December 2023. She had “the worst headache of (her) life” when she went to the emergency room on Dec. 15.

“I just wasn’t functioning like a normal human being,” Jabeen says.

Told she was dehydrated, Jabeen was given fluids and a blood test and sent home. Four days later, she returned to hospital.

“They told me that since you’re 18 weeks, there’s nothing you can do to save your baby,” says Jabeen, who moved to Toronto from Pakistan five years ago.

Jabeen later learned she had listeriosis and an autopsy revealed her baby was infected, too.

“It broke my heart to read that report because I was just imagining my baby drinking poisoned amniotic fluid inside of me. The womb is a place where your baby is supposed to be the safest,” Jabeen said.

Jabeen’s case is likely not included in PHAC’s count. Jabeen says she was called by Health Canada and asked what dairy and fresh produce she ate – foods more commonly associated with listeria – but not asked about plant-based beverages.

She’s pregnant again, and is due in several months. At first, she was scared to eat, not knowing what caused the infection during her last pregnancy.

“Ever since I learned about the almond, oat milk situation, I’ve been feeling a bit better knowing that it wasn’t something that I did. It was something else that caused it. It wasn’t my fault,” Jabeen said.

She’s since joined a proposed class action lawsuit launched by LPC Avocates against the manufacturers and sellers of Silk and Great Value plant-based beverages. The lawsuit has not yet been certified by a judge.

Natalie Grant and her seven year-old daughter, Bowmanville, Ont.

Natalie Grant says she was in a hospital waiting room when she saw a television news report about the recall. She wondered if the dark chocolate almond milk her daughter drank daily was contaminated.

She had brought the girl to hospital because she was vomiting every half hour, constantly on the toilet with diarrhea, and had severe pain in her abdomen.

“I’m definitely thinking that this is a pretty solid chance that she’s got listeria at this point because I knew she had all the symptoms,” Grant says of seeing the news report.

Once her daughter could hold fluids, they went home and Grant cross-checked the recalled product code – 7825 – with the one on her carton. They matched.

“I called the emerg and I said I’m pretty confident she’s been exposed,” Grant said. She was told to return to the hospital if her daughter’s symptoms worsened. An hour and a half later, her fever spiked, the vomiting returned, her face flushed and her energy plummeted.

Grant says they were sent to a hospital in Ajax, Ont. and stayed two weeks while her daughter received antibiotics four times a day until she was discharged July 23.

“Knowing that my little one was just so affected and how it affected us as a family alone, there’s a bitterness left behind,” Grant said. She’s also joined the proposed class action.

Thelma Feldman, 89, Toronto

Thelma Feldman says she regularly taught yoga to friends in her condo building before getting sickened by listeria on July 2. Now, she has a walker and her body aches. She has headaches and digestive problems.

“I’m kind of depressed,” she says.

“It’s caused me a lot of physical and emotional pain.”

Much of the early days of her illness are a blur. She knows she boarded an ambulance with profuse diarrhea on July 2 and spent five days at North York General Hospital. Afterwards, she remembers Health Canada officials entering her apartment and removing Silk almond milk from her fridge, and volunteers from a community organization giving her sponge baths.

“At my age, 89, I’m not a kid anymore and healing takes longer,” Feldman says.

“I don’t even feel like being with people. I just sit at home.”

Jasmine Jiles and three-year-old Max, Kahnawake Mohawk Territory, Que.

Jasmine Jiles says her three-year-old son Max came down with flu-like symptoms and cradled his ears in what she interpreted as a sign of pain, like the one pounding in her own head, around early July.

When Jiles heard about the recall soon after, she called Danone Canada, the plant-based milk manufacturer, to find out if their Silk coconut milk was in the contaminated batch. It was, she says.

“My son is very small, he’s very young, so I asked what we do in terms of overall monitoring and she said someone from the company would get in touch within 24 to 48 hours,” Jiles says from a First Nations reserve near Montreal.

“I never got a call back. I never got an email”

At home, her son’s fever broke after three days, but gas pains stuck with him, she says. It took a couple weeks for him to get back to normal.

“In hindsight, I should have taken him (to the hospital) but we just tried to see if we could nurse him at home because wait times are pretty extreme,” Jiles says, “and I don’t have child care at the moment.”

Joseph Desmond, 50, Sydney, N.S.

Joseph Desmond says he suffered a seizure and fell off his sofa on July 9. He went to the emergency room, where they ran an electroencephalogram (EEG) test, and then returned home. Within hours, he had a second seizure and went back to hospital.

His third seizure happened the next morning while walking to the nurse’s station.

In severe cases of listeriosis, bacteria can spread to the central nervous system and cause seizures, according to Health Canada.

“The last two months have really been a nightmare,” says Desmond, who has joined the proposed lawsuit.

When he returned home from the hospital, his daughter took a carton of Silk dark chocolate almond milk out of the fridge and asked if he had heard about the recall. By that point, Desmond says he was on his second two-litre carton after finishing the first in June.

“It was pretty scary. Terrifying. I honestly thought I was going to die.”

Cheryl McCombe, 63, Haliburton, Ont.

The morning after suffering a second episode of vomiting, feverish sweats and diarrhea in the middle of the night in early July, Cheryl McCombe scrolled through the news on her phone and came across the recall.

A few years earlier, McCombe says she started drinking plant-based milks because it seemed like a healthier choice to splash in her morning coffee. On June 30, she bought two cartons of Silk cashew almond milk.

“It was on the (recall) list. I thought, ‘Oh my God, I got listeria,’” McCombe says. She called her doctor’s office and visited an urgent care clinic hoping to get tested and confirm her suspicion, but she says, “I was basically shut down at the door.”

Public Health Ontario does not recommend listeria testing for infected individuals with mild symptoms unless they are at risk of developing severe illness, such as people who are immunocompromised, elderly, pregnant or newborn.

“No wonder they couldn’t connect the dots,” she adds, referencing that it took close to a year for public health officials to find the source of the outbreak.

“I am a woman in my 60s and sometimes these signs are of, you know, when you’re vomiting and things like that, it can be a sign in women of a bigger issue,” McCombe says. She was seeking confirmation that wasn’t the case.

Disappointed, with her stomach still feeling off, she says she decided to boost her gut health with probiotics. After a couple weeks she started to feel like herself.

But since then, McCombe says, “I’m back on Kawartha Dairy cream in my coffee.”

B.C. mayors seek ‘immediate action’ from federal government on mental health crisis

Published

 on

 

VANCOUVER – Mayors and other leaders from several British Columbia communities say the provincial and federal governments need to take “immediate action” to tackle mental health and public safety issues that have reached crisis levels.

Vancouver Mayor Ken Sim says it’s become “abundantly clear” that mental health and addiction issues and public safety have caused crises that are “gripping” Vancouver, and he and other politicians, First Nations leaders and law enforcement officials are pleading for federal and provincial help.

In a letter to Prime Minister Justin Trudeau and Premier David Eby, mayors say there are “three critical fronts” that require action including “mandatory care” for people with severe mental health and addiction issues.

The letter says senior governments also need to bring in “meaningful bail reform” for repeat offenders, and the federal government must improve policing at Metro Vancouver ports to stop illicit drugs from coming in and stolen vehicles from being exported.

Sim says the “current system” has failed British Columbians, and the number of people dealing with severe mental health and addiction issues due to lack of proper care has “reached a critical point.”

Vancouver Police Chief Adam Palmer says repeat violent offenders are too often released on bail due to a “revolving door of justice,” and a new approach is needed to deal with mentally ill people who “pose a serious and immediate danger to themselves and others.”
