Experimental COVID-19 vaccine is put to its biggest test – Egypt Independent

The biggest test yet of an experimental COVID-19 vaccine got underway Monday with the first of some 30,000 Americans rolling up their sleeves to receive shots created by the US government as part of the all-out global race to stop the pandemic.

The glimmer of hope came even as Google, in one of the gloomiest assessments of the coronavirus’s staying power from a major employer, decreed that most of its 200,000 employees and contractors should work from home through next June — a decision that could influence other big companies.

Final-stage testing of the vaccine, developed by the National Institutes of Health and Moderna Inc., began with volunteers at numerous sites around the US given either a real dose or a dummy without being told which.

“I’m excited to be part of something like this. This is huge,” said Melissa Harting, a 36-year-old nurse who received an injection in Binghamton, New York. Especially with family members in front-line jobs that could expose them to the virus, she added, “doing our part to eradicate it is very important to me.”

Another company, Pfizer Inc., announced late Monday that it had started its own study of its vaccine candidate in the US and elsewhere. That study also aimed to recruit 30,000 people.

It will be months before results trickle in, and there is no guarantee the vaccines will ultimately work against the scourge that has killed over 650,000 people around the world, including almost 150,000 in the US.

“We’ve been sitting on the sidelines passively attempting to wear our masks and social distance and not go out when it’s not necessary. This is the first step of becoming active against this,” said Dr. Frank Eder of Meridian Clinical Research, the company that runs the Binghamton trial site. “There’s really no other way to get past this.”

As if to underline how high the stakes are, there were more setbacks in efforts to contain the coronavirus.

In Washington, the Trump administration disclosed that national security adviser Robert O’Brien has the virus — the highest-ranking US official to test positive so far. The White House said he has mild symptoms and “has been self-isolating and working from a secure location off site.”

The move to restart the national pastime ran into trouble just five days into the long-delayed season: Two major league baseball games scheduled for Monday night were called off as the Miami Marlins coped with an outbreak — the Marlins’ home opener against the Baltimore Orioles, and the New York Yankees’ game in Philadelphia, where the Marlins used the clubhouse over the weekend.

As for relief from the economic damage done by the virus, Republicans on Capitol Hill rolled out a $1 trillion package that includes another round of $1,200 direct payments but reduces the extra $600 a week in federal unemployment benefits that expire for millions of Americans on Friday. Republicans proposed $200 a week, saying the generous bump discourages people from returning to work. Democrats call the added benefits a lifeline for those who have lost their jobs.

Treasury Secretary Steven Mnuchin and White House chief of staff Mark Meadows worked through the weekend on the GOP proposal and have agreed to negotiate with House Speaker Nancy Pelosi and Democratic Senate leader Chuck Schumer. House Democrats passed a $3 trillion relief package a couple of months ago.

In Europe, rising infections in Spain and other countries caused alarm only weeks after nations reopened their borders in hopes of reviving tourism. Over the weekend, Britain imposed a 14-day quarantine on travelers arriving from Spain, Norway ordered a 10-day quarantine for people returning from the entire Iberian peninsula, and France urged its citizens not to visit Spain’s Catalonia region.

Scientists set speed records getting vaccines into massive testing just months after the coronavirus emerged. But they stressed that the public shouldn’t fear that anyone is cutting corners.

“This is a significant milestone,” NIH Director Francis Collins said after the first test injection of Moderna’s vaccine was given, at 6:45 a.m. in Savannah, Georgia. “Yes, we’re going fast, but no, we are not going to compromise” on proving whether the vaccine is safe and effective.

“We are focusing on speed because every day matters,” added Stephane Bancel, CEO of Massachusetts-based Moderna.

After volunteers get two doses a month apart, scientists will closely track which group experiences more infections as they go about their daily routines, especially in areas where the virus is spreading unchecked.

The answer probably won’t come until November or December, cautioned Dr. Anthony Fauci, NIH’s infectious-diseases chief.

Among many questions the study may answer: How much protection does just one dose offer compared with the two scientists think are needed? If it works, will it protect against severe disease or block infection entirely?

Don’t expect a vaccine as strong as the measles vaccine, which prevents about 97% of measles infections, Fauci said, adding he would be happy with a COVID-19 vaccine that’s 60% effective.

Several other vaccines made by China and by Britain’s Oxford University began smaller final-stage tests in Brazil and other hard-hit countries earlier this month. But the U.S. requires its own tests of any vaccine that might be used in the country.

Every month through the fall, the government-funded COVID-19 Prevention Network will roll out a new study of a leading candidate, each with 30,000 volunteers.

The final US study of the Oxford shot is set to begin in August, followed by a candidate from Johnson & Johnson in September and one from Novavax in October.

That’s a stunning number of people needed to roll up their sleeves for science. In recent weeks, more than 150,000 Americans filled out an online registry signaling interest, Collins said. But many more are needed.

NIH is working to make sure that the study isn’t just filled with healthy, younger volunteers but includes populations hit hardest by COVID-19, including older adults, those in poor health and African-Americans and Latinos.

“We really are going to depend upon that sense of volunteerism for individuals from every different corner of society if we’re going to really find out how this vaccine, and its potential to end this terrible pandemic, is go to work in each of those groups,” Collins said.

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.”
