Future of AstraZeneca COVID-19 vaccine in question in Canada over blood clots, supply issues

 Evan Mitsui/CBC Ontario and Alberta will no longer give the AstraZeneca-Oxford vaccine as a first dose and future supply would instead be reserved for optional second shots.

The future use of the AstraZeneca-Oxford COVID-19 vaccine in Canada is now in question due to concerns over the increased risk of rare but severe blood clots connected to the shot, an unpredictable future supply and a significant amount of other vaccines.

Alberta was the first province to confirm it would stop administering first doses of the AstraZeneca vaccine, citing a scarcity of supply. The province will instead prioritize mRNA vaccines like Pfizer-BioNTech and Moderna while reserving existing AstraZeneca for second doses.

Ontario's Chief Medical Officer Dr. David Williams announced in an impromptu news conference late Tuesday afternoon the vaccine would also no longer be offered to Ontarians as a first dose and future supply would instead be reserved for optional second shots.

But unlike Alberta, Ontario's decision was made largely due to the rising rate of the rare but serious blood-clotting condition connected to the shot known as vaccine-induced immune thrombotic thrombocytopenia (VITT).

Williams said that in the past several days there have been a growing number of reports of VITT in Ontario. Out of more than 850,000 AstraZeneca doses given, there are now eight cases in the province as of Saturday at a rate of about one in 60,000 shots administered.

Other provinces have yet to follow suit, but there are growing signs the vaccine will not be prioritized in provincial and territorial rollouts across the country.

Quebec's Ministry of Health and Social Services said in a statement to CBC News that while the AstraZeneca vaccine is still technically available to people over 45, the remaining doses have almost all expired and mRNA vaccines will be offered if a second dose is unavailable.

Manitoba's Chief Provincial Public Health Officer Dr. Brent Roussin said Sunday that the possibility of stopping the use of the AstraZeneca vaccine was being discussed "at many levels."

British Columbia Provincial Health Officer Dr. Bonnie Henry said Tuesday that while second doses of the AstraZeneca vaccine will be available to those who already had a shot in the province, mRNA vaccines will also be an option.

New international research is expected in the coming days and weeks on the safety and efficacy of mixing and matching COVID-19 vaccines and Canadians who have received an initial dose of AstraZeneca will likely have the option of combining it with an mRNA shot.

"I cannot emphasize enough how important AstraZeneca has been, in particularly March and April when we had limited amounts of the mRNA vaccine and we had high case rates and it's a very good vaccine and very protective," she told CBC's The Early Edition.

"But as we have case rates coming down thankfully and hopefully staying down, and we have a lot more other vaccines available, we'll be looking at using the Pfizer and Moderna that's coming in."

VITT data 'evolving' in real time

The abrupt change in vaccine rollout strategy comes after growing concerns from health experts over the risk of VITT, which they say calls its continued use in Canada into question.

Dr. Andrew Morris, an infectious diseases specialist at the University of Toronto, says the use of the AstraZeneca vaccine in Canada is no longer justifiable, particularly in younger people.

"For the people who are in their 30s and 40s, it just doesn't make sense," he said. "They're at really low risk of dying from COVID and they're assuming a risk of dying from this."

Health Canada approved the AstraZeneca vaccine for all Canadians over 18 in February, but provinces and territories have largely restricted its use in those over 40 due to the increased risk of VITT in younger age groups compared with the risk of death from COVID-19.

Though extremely rare, VITT is much more severe than a typical blood clot because it can cause cerebral venous sinus thrombosis (CVST), where veins that drain blood from the brain are obstructed and can potentially cause fatal bleeding.

Dr. Menaka Pai, a clinical hematologist at McMaster University and a member of Ontario's COVID-19 Science Advisory Table, says that the risk of VITT is changing almost daily and that different guidelines are to be expected.

"The reality is this is what evolving science looks like," she said. "We're asking people to make decisions in real time with the info that we have and then the info evolves a week later and we can be regretful about the decision from a week ago but hindsight is 20/20."

Pai says each region of the country needs to look at its specific epidemiological situation in the pandemic and determine whether the risk of VITT outweighs the risk of severe outcomes from COVID-19.

"What works in a hotspot where you don't have enough mRNA vaccines to quickly cover everyone [may not work] in parts of the Maritimes where you actually have a lot of places with low prevalence," she said.

"If you don't have the privilege of choice because your pandemic is out of control, I think that changes the math a lot and it changes the decision-making."
VITT risk 'increasing' as cases identified

Canada has reported 12 confirmed cases of VITT as of Monday out of more than 2.3 million AstraZeneca doses administered, according to the Public Health Agency of Canada. Quebec, Alberta and New Brunswick have each reported one death; New Brunswick has only 40 COVID-19 deaths overall.

"In a province with low COVID-19 risk like New Brunswick, the risk of death from VITT outweighs the risk of death from COVID-19 at any age," said Dr. David Fisman, an epidemiologist at the University of Toronto's Dalla Lana School of Public Health.

The Ontario Science Table now estimates the frequency of VITT in Canadians who have received the AstraZeneca vaccine at 1 in 55,000, but that number is a moving target with new data being released from countries around the world daily.

"Risk estimates have been increasing as people have started looking for the complication," said Fisman. "It doesn't make sense to use a vaccine where short term harms outweigh short term benefits, when people can stay safe until they get mRNA vaccine."

The National Advisory Committee on Immunization (NACI) came under fire last week for its messaging around its recommendations to provinces and territories that mRNA vaccines such as Pfizer-BioNTech and Moderna, which don't have a risk of VITT, were "preferred."

PHAC said in a statement to CBC News that as the supply of mRNA vaccines like Pfizer and Moderna increase this month, it is "expected" that provinces and territories will "continue to review and adjust their vaccination programs."

Morris says he believes more cases and deaths from VITT will occur in Canada in the future if we continue to use the AstraZeneca vaccine as a significant part of our vaccine rollout.

"You have to be pretty certain that the people who you're giving it to have a really, really, really high risk of death from COVID," he said. "So that the risk of death that you're exposing them to is exceeded by the risk of death that you're preventing."
AstraZeneca use in other countries

Denmark has completely halted the use of the AstraZeneca vaccine due to the risk of VITT, in addition to the Johnson & Johnson vaccine, which uses a similar adenoviral vector method. The move that is expected to set the country back weeks in its vaccine rollout.

The United Kingdom has used the AstraZeneca vaccine as a significant part of its vaccination campaign to successfully control its pandemic and is now able to relax public health restrictions due in large part to the use of the shot.

But VITT was not yet identified when that rollout was in full swing at the beginning of the year and the U.K. restricted the vaccine to those over 40 last week and retroactively reported 242 cases of VITT and 49 deaths out of 28.5 million doses given up to April 28.

The Ontario Science Table says that VITT can present anywhere from four to 28 days after vaccination and Canadians should seek medical attention if they have any of the symptoms listed on its website.

Pai says Canadians who are concerned about having taken an initial dose of the AstraZeneca vaccine despite not having VITT symptoms should rest assured that they made a smart choice at a critical point in the pandemic.

"You guys made an amazing, amazing decision based on the information in front of you," she said. "And now doctors, like me are trying to educate you if there is a very rare risk."

'Very little excuse' to continue to use AstraZeneca in Canada: infectious diseases specialist

It’s time to halt AstraZeneca shots in Canada, except for people 40 or older in hotspots, says Andrew Morris, a doctor on Ontario’s COVID-19 science advisory table

The peculiar blood clotting disorder linked with Oxford-AstraZeneca’s COVID-19 vaccine, a vaccine now temporarily paused in Ontario and Alberta, doesn’t cause the regular kind of blood clots. These clots require more extensive care, they can’t be predicted and, most importantly, are “really kinda bad,” says a Toronto infectious diseases specialist. The case fatality rate ranges between 20 and 40 per cent.

For those reasons and more, Dr. Andrew Morris believes it’s time to halt AstraZeneca’s shots across the country, except where COVID-19 is burning and people at very high risk of COVID cannot wait for a Pfizer-BioNTech or Moderna shot — mRNA vaccines that haven’t been associated with the same blood clot “safety signal.”

There is “essentially no scenario” outside of the hardest-hit regions where it is beneficial to give AstraZeneca rather than wait for an alternative, Morris, a member of Ontario’s COVID-19 science advisory table, said in an interview. While stressing that he wasn’t speaking on behalf of the table, “there is very little excuse for us to be continuing to give AstraZeneca to Canadians” because the estimated risk of the unusual clotting disorder is higher than earlier, overly optimistic estimates, Morris said.

At a hastily called news conference Tuesday, Ontario health officials announced the province is pausing first doses of the AstraZeneca vaccine out of an “abundance of caution” because of the risk of thrombosis and an abundance of mRNA vaccine supply. Alberta is also moving to stop using AstraZeneca for first doses.

There is very little excuse for us to be continuing to give AstraZeneca to Canadians


The risk of VITT — vaccine-induced thrombotic thrombocytopenia — now sits at one in 60,000 doses, based on Ontario data. “That’s a significant safety signal that we don’t want to ignore,” said Dr. Jessica Hopkins of Public Health Ontario. The province has about 50,000 remaining doses of AstraZeneca. “Given that we are seeing the overall case numbers of COVID going down and an increase in the safety signal, at a population level, it makes sense to pause AstraZeneca because the risk of severe outcomes with VITT shouldn’t be underestimated.”

Other provincial medical officers of health across the country are reviewing their use of the controversy-plagued vaccine. The European Union, meanwhile, has opted not to renew its AstraZeneca contracts, which expire in June. In Norway, an expert panel is urging both AstraZeneca and Johnson & Johnson vaccines be ditched over the blood clot scare.

According to Health Canada, the current estimated rate of VITT in Canada is approximately one case per 100,000 persons vaccinated with the AstraZeneca vaccine.

Ontario’s COVID science table, in a brief published Friday, said the risk, based on published estimates, could be as much as one in 26,000.

Morris’ best estimate is that one in 40,000 doses will lead to VITT, a condition that frequently results in complications, with about one in five leading to death and many more cases of severe illness. Given the risk, AstraZeneca only makes sense for those at very high risk of COVID, he said. “But why give them AZ, when we can give them an mRNA vax?”

Ontario likely to give mixed COVID vaccine doses due to shortage of AstraZeneca: minister


Twelve cases of VITT have been reported in Canada, including three deaths. “To me, the most important issue is, we were aware of this a month ago — we probably didn’t appreciate the frequency as much a month ago, although we suspected it,” Morris said.

With two million combined doses of Pfizer and Moderna arriving weekly through May, and 2.4 million combined doses per week scheduled for June, Canada will soon be “swimming in vaccine,” Morris said. “I think that the regulators should say very clearly that, if there are no options for an mRNA vaccine and the incidence of cases is X number, then only in that situation should AstraZeneca be used.”

Some worry this messaging will only make people more confused and concerned. But others agree with Morris. “I’ve done the numbers, too,” University of Toronto epidemiologist David Fisman said on Twitter. “AZ was a useful tool, but our knowledge and understanding, and our supply of other vaccines, has changed. VITT is devastating. We need to move on.”

Just over two million of the 2.3 million doses of AstraZeneca doses delivered to the provinces had been administered as of Monday. The remaining vials won’t “make or break the pandemic” and the shots are likely going to people who are at relatively low risk of COVID, Morris said, meaning “we’re introducing unnecessary risk into people who have relatively low COVID risk.” The 20 million doses on order from an American plant should be donated to India and other countries, he said.

“If we could get a billion doses of AstraZeneca to India, I would do it in a heartbeat, because so many people are dying. And yes, some of those people will die (from vaccine-induced blood clotting) but you’re going to be saving millions and millions of lives,” said Morris, a professor of medicine at the University of Toronto and infectious diseases doctor at Sinai Health and University Health Network.

This shouldn’t be construed as buyer’s remorse, he said. People should not feel as if they were somehow “hoodwinked” into getting AstraZeneca. Every authorized COVID vaccine in Canada has been “absolutely life-saving.” A new analysis just out from Public Health England suggests a single dose of either the AstraZeneca or Pfizer-BioNTech vaccine is 80 per cent effective at preventing death from COVID. That rises to 97 per cent after two doses of Pfizer.

If we could get a billion doses of AstraZeneca to India, I would do it in a heartbeat


When COVID is raging, “it’s a total no-brainer (to use AstraZeneca) because, even if you are adding that small risk of harm, it’s outweighed by the benefit,” Morris said.

But outside of hard-hit Calgary, Edmonton, Winnipeg, Peel, Halifax and other pockets, the third wave is cresting or receding in most parts of the country.

Ontario is offering AstraZeneca to 40 and older. Of the 24,655 COVID-related deaths reported in Canada as of Monday, only 1.6 per cent, or 390, are in people under age 50, and three per cent (749) in people in their 50s.

The blood-clotting syndrome linked to the AstraZeneca vaccine happens four to 28 days after being vaccinated. The mechanism isn’t entirely clear, but it’s thought the body produces antibodies that attack platelets, tiny blood cells that form clots to stop or prevent bleeding. Serious clots have been reported in the brain and other critical organs. The clots can cause strokes, heart attacks and loss of blood supply to a limb.

Canada’s panel of independent vaccination advisors last week reiterated that Pfizer and Moderna remain the “preferred” recommended jabs for all Canadians, and that people at low risk of COVID should consider holding out for an mRNA vaccine, unless they choose to get vaccinated sooner.

However, the second dose question remains — what happens to those who received a single dose of AstraZeneca? Should they get AZ for dose two? According to U.K. data, the risk of VITT after a second dose of the vaccine is one in a million.

Officials are now awaiting the results of a large study in the U.K. that’s tested alternating doses of AstraZeneca and Pfizer in hundreds of volunteers.

The chances that there will be an issue with mixing vaccines are slim to none

“The chances that there will be an issue with mixing vaccines are slim to none,” said Dr. Allison McGeer, a medical microbiologist and infectious diseases specialist at Toronto’s Sinai Health System. “There are a lot of things keeping me awake at night. This is not one of them.”

“The rules have always been that we don’t ask people to be vaccinated if the vaccine is not a direct benefit to them,” McGeer said. “And the calculus of direct benefit to a person for the AstraZeneca vaccine at the moment is really difficult. It depends on community rates around the person, the individual involved, how well they can protect themselves, how sick they’re going to get if they happen to get COVID, what the probability of VITT is and how long people are going to have to wait for Pfizer or Moderna if they don’t choose to get AstraZeneca.”

With COVID rates dropping in most parts of the country, “that changes the calculations of risk in a non-trivial way,” McGeer said.

“If you got your AstraZeneca vaccine more than a month ago, that’s a good decision with a good outcome,” she said. “I know all sorts of people — my husband, my sister, lots of people — who got the AstraZeneca vaccine and it was a good decision at the time.

“This is the thing about pandemics. New diseases. Things change. The right thing to do changes over time.”

Trust in Canadian political leaders has cratered during the pandemic, poll finds — except in Quebec
AB ELECTION 2023 CAN KENNEY LAST THAT LONG
The survey suggests that incumbent governments — at least from Ontario westward — may run into trouble when the next election comes around

OTTAWA — A new poll suggests that most Canadians have less trust in their current political leadership because of how the COVID-19 pandemic was handled, with Alberta Premier Jason Kenney, Ontario Premier Doug Ford, and Prime Minister Justin Trudeau taking the worst hits.

But the poll also found one province to be a notable outlier: Quebec, where respondents reported a substantial increase in trust in Premier François Legault’s leadership. The only other place where respondents reported an increase in trust was in Atlantic Canada, though the gains were much less than in Quebec.

The survey suggests that incumbent governments — at least from Ontario westward — may run into trouble when the next election comes around.

The poll surveyed 1,500 Canadians from April 30 to May 4, and was conducted by public strategy firm Navigator’s research division, called Discover by Navigator.

The political leaders of Ontario and Alberta fared the worst in how the public’s trust has changed during the pandemic, the poll found. Both provinces have seen massive third waves this spring that have resulted in strict lockdowns to ease the pressure on hospitals.

Fifty-four per cent of Albertans said they have less trust in Kenney now because of the pandemic, with just 13 per cent saying they have more. In Ontario, 51 per cent said they have less trust in Ford, while 20 per cent said their trust has increased.

The poll uses the difference between the two trust numbers to create a “pandemic trust progression score,” which puts Kenney at -41 and Ford at -31.

Prime Minister Justin Trudeau, meanwhile, also suffered a hit in his trust score with the public. The poll found 44 per cent have less trust in Trudeau, while 19 per cent have more, giving him a -25 trust score.

Perhaps unsurprisingly, Alberta saw the steepest drop in trust for Trudeau, with a trust score of -43. But his second worst numbers were found in B.C., where half of respondents said their trust in him has decreased and only 15 per cent said it increased. Trudeau fared relatively poorly in the other regions as well, except for Atlantic Canada, where his trust score was +3.

B.C. Premier John Horgan had slightly better numbers but still negative overall, with 35 per cent of British Columbians saying they trust him less now and 22 per cent saying they trust him more.

One exception to the public’s eroding trust is in Atlantic Canada, where the poll found slightly more trust overall for the premiers.

The much greater exception is Quebec, however, where trust in Legault has soared. The poll found 43 per cent of Quebeckers saying they trust Legault more now, while 20 per cent said they trust him less. This lines up with other recent public polling that has found Legault performing well in public support.

Navigator principal André Pratte, a former Canadian senator and editorial writer with Quebec newspaper La Presse, said Legault’s numbers are a bit surprising given Quebec’s rocky pandemic performance in the early months, when its case count and death rate were the highest in the country.

But Quebec has seen a milder third wave than other provinces, and Pratte said there might be other reasons that have also helped Legault.

“When (the pandemic) happened in long-term care homes, people knew that Legault had been there for a year, you can’t put all the problems on him,” Pratte said. “So that’s number one. And he was transparent. He did take part of the blame, he did not avoid the tough questions. So I think that’s part of it. And in Quebec, at least, the opposition parties were already weak from the beginning.”



Pratte said trying to map out the political consequences of this isn’t as simple as it might seem.

“This is not voting intentions,” he said. “Trust is part of it. It’s an important part of it. But it doesn’t mean that anything is definitive.”

Still, he said Legault’s strong public support could spell trouble for Trudeau in the province, which is always influential in federal elections given it has a quarter of all seats. The poll found 37 per cent of Quebec respondents had less trust in Trudeau now, compared to 23 per cent who had more.

“If I was a Liberal organizer, I’d be worried by the numbers in Quebec,” Pratte said. “Many races will be very, very tight in Quebec. The Bloc Québécois is doing quite well, the Conservatives have high hopes also. So anything is possible.”

The poll also asked respondents about other institutions and organizations during the pandemic. It found large businesses had a trust score of -18, small and medium businesses had a trust score of +22, and doctors and healthcare workers had the highest overall trust score at +38.
This is why Vancouver has become North America's anti-Asian hate crime capital

Bloomberg News 
© Provided by National Post British Columbia is facing an undercurrent of racism that began when the first Asians landed on its shores to search for gold, and to help build the railway.

It’s said to be the most Asian city outside Asia. Where a quarter of residents speak a Chinese language and the char siu rivals what’s served in Hong Kong barbecue shops. Where a Sikh gurdwara, a Tibetan monastery and a Chinese evangelical church coexist in harmony along a three-kilometre stretch of road dubbed the Highway to Heaven. The kind of place that should be immune to a rise in pandemic-fuelled racism.

Vancouver has been anything but.


Last year, more anti-Asian hate crimes were reported to police in Vancouver than in the top 10 most populous U.S. cities combined. With almost one out of every two residents of Asian descent in British Columbia experiencing a hate incident in the past year, the region is confronting an undercurrent of racism that runs as long and deep as the historical links stretching across the Pacific.

COVID-19 was the trigger. But the resentment had been building for decades. Few areas have been so visibly transformed by Asian immigration — and money — as the Lower Mainland. Vancouver itself has become a glittering cosmopolis of luxury condos and designer boutiques. The disproportionate rash of incidents has raised an unsettling question: Maybe Vancouver isn’t the bastion of progressive multiculturalism it thinks it is.

“COVID has just revealed what’s always been there,” says Trixie Ling, 38, a Taiwan-born immigrant who three years ago founded a nonprofit called Flavours of Hope to assist refugee women. She was accosted in May 2020 by a man who spewed a stream of racist and sexist insults before spitting in her face. “There is so much anti-Asian racism in our past that carries through.”

The recent backlash against the broader Asian community started almost as soon as COVID-19 began spreading beyond China in early 2020, with Vancouver seemingly poised to become an epicentre. The city had more direct flights with mainland China than any other in the Americas or Europe. A local businessman flying home from Wuhan became B.C.’s Case 1 on Jan. 26, among the first detected outside Asia at the time .

Months later, it would become clear that route wasn’t, in fact, the principal cause of the virus’s spread in the area: Epidemiological studies showed that the primary source of infections was strains from Europe, Eastern Canada and Washington state.

But in the early weeks of the pandemic, simply looking Asian and wearing a mask in Vancouver triggered verbal assaults such as “Virus spreaders,” “Go back to China” and “Stop stealing masks from frontline workers.” The attacks quickly escalated: One 92-year-old was hurled out of a convenience store to the sidewalk; a woman was punched in the head at a downtown bus stop in broad daylight. Vandals repeatedly defaced statues and buildings in Chinatown with racist graffiti.

In 2020, Vancouver police documented 98 anti-Asian hate crimes, an eightfold increase from the prior year. That was triple the number recorded in New York, which logged the most of any U.S. city, according to police data collected by the Center for the Study of Hate and Extremism at California State University at San Bernardino.

Of course, most incidents go unreported. An April 9 survey by Vancouver-based pollster Insights West revealed that 43 per cent of B.C. residents of Asian descent say they experienced a racist incident in the past year, ranging from racial slurs to property damage to physical assault. And almost half say they believe the racism will get worse. A report by the Chinese Canadian National Council for Social Justice in September found that Canada, per capita, had a higher incidence of anti-Asian racism than the U.S., with B.C. topping the list of provinces reporting incidents.

For those living in Richmond, just south of Vancouver proper, where ethnic Chinese constitute 54 per cent of the population, it’s been a particularly bitter irony. Richmond residents began practicing social distancing and donning face masks even before the province’s first case was detected. Months later, public-health officials and researchers would commend the local Chinese community for playing a key role in containing the virus’s early spread. More than a year into the pandemic, Richmond’s total infection rate remains dramatically low, closer to that of Nunavut than to the Vancouver metropolitan area.

‘Wuhan pneumonia’: Ontario MPPs urge Chinese-Canadian doctor to remove ‘divisive’ sign

Vancouver came to exist as the Pacific Coast terminus of Canada’s first transcontinental railway — Chinese labourers were able to lay more than six miles of track in a single day, but at a terrible price. Two Chinese workers died for every mile laid on the final treacherous stretch through the Rockies in the late 1800s, according to records at the University of British Columbia. Three decades earlier, during the gold rush, Chinese men worked only abandoned mines in order not to incur the anger of white miners.

Historically, Canada’s worst excesses against Asian communities trace their roots to the Lower Mainland — from the hefty “head tax” Ottawa began levying in 1885 on every Chinese person entering the country, to a decades-long ban on Chinese immigration, to the forced internment of some 22,000 Japanese Canadians during the Second World War that, unlike in the U.S., also stripped families of their assets. Covenants barring the sale of properties to those of “African or Asiatic descent” survive in land titles in some of Vancouver’s toniest neighbourhoods, even though the restrictions were nullified in 1978.

Many still recall how quickly the hate flared, including Kayoko Nomura, 85, who as a child was taken from her home in the coastal town of Ocean Falls and corralled into a livestock pen with her mother and siblings at a Japanese detention camp 1,000 km south in Vancouver.

Twice in recent months she’s been the target of racist tirades. First, a driver in a Home Depot parking lot yelled at her to go back to her country, then a woman at Costco unleashed a hateful rant after Nomura picked up a magazine with gloves on. Community groups report Asian elders saying they haven’t felt such intense levels of hate since the war.

After a lifetime of slights and insults, Nomura thought she was inured to most. “People my age tend to grin and bear it,” says the octogenarian, who didn’t report the incidents to the police. “I guess it is time that all of us should be speaking out.”

The latest spike in hate crimes also draws from a more recent chapter in Vancouver’s history, one in which Asians, once stigmatized as an immigrant underclass, have been increasingly perceived as elites with rancor-inducing wealth. By the 1980s, close to half of all immigrants being admitted into Canada were from Asia; most weren’t rich, but increasingly the country was tweaking its policies to attract the wealthy.

In Vancouver, a conspicuous group of well-heeled newcomers emerged, none more visible than Li Ka-shing . The legendary Hong Kong tycoon in 1988 acquired one-sixth of downtown properties and redrew the skyline with a cluster of tall, glassy condominiums. (To be sure, his group fostered little goodwill by pre-selling an entire tower exclusively to Hong Kong buyers without offering a single unit locally.) Over the next decade, some Hong Kong immigrants moved to Canada in the lead-up to the British colony’s return to Chinese rule in 1997.

“Is Vancouver Becoming a Suburb of Hong Kong?” screamed the March 1988 cover of Equity , a Vancouver business magazine. In the 1990s a furor raged in public hearings on zoning rules over the newcomers’ so-called monster homes destroying the esthetics of traditionally wealthy, white neighbourhoods (the ones with the voided covenants). Yet by 2010, Americans would come to own four times as many Vancouver properties as Hong Kongers at the time — to scant outrage.

Like some chronic condition, the xenophobia would subside for a time only to flare up again later, triggered by anxieties over access to housing or education.

Around 2014 a particularly dizzying surge in home prices began. With cheap money inflating asset prices worldwide, Vancouver found itself at the centre of a global property boom. Double-digit gains in home prices outpaced those in New York and London

A more visible phenomenon in Vancouver’s small, shallow economy was an influx of Chinese money fleeing Beijing’s tightening capital controls. Signs included buses emblazoned with wraparound realtor ads in Chinese, as well as Asian college students parading in Lamborghinis and Aston Martins. The University of British Columbia has often colloquially been referred to as the University of Beautiful Cars — or the University of a Billion Chinese.

The ostentatious displays of wealth by the fuerdai — the label the Chinese apply to children of the nouveau riche — rankled in a city gripped by a housing affordability crisis. Newspapers were filled with tales of cash-rich Asian buyers besting locals in bidding wars and upscale neighbourhoods turned desolate as absentee owners left properties empty and condominium towers dark at night.

A controversial 2015 study sought to determine the level of foreign ownership — in the absence of data at the time — by screening for non-Anglicized Chinese names in three wealthy neighbourhoods. The study — based on just 172 sales out of more than 42,000 transactions that year — was facilitated by David Eby, then an opposition politician. It became fodder for dozens of news stories over the next few years as definitive evidence of Chinese buyers driving the market, avoiding taxes, flipping properties and receiving unfair access to bank financing.

Eby, now the province’s attorney general and minister responsible for housing, last month apologized for his role in the study, acknowledging his comments at the time had helped perpetuate a harmful narrative against Chinese money.

© Postmedia file photo A more detailed study of the Vancouver real estate market unearthed the fact that buyers — not primarily Chinese buyers — were enticed by low interest rates and low property taxes.

Starting in 2016, Vancouver and the rest of British Columbia became a laboratory for policies designed to deter rich foreigners from investing in real estate. A series of measures rolled in: first a foreign-buyer tax, then an empty-homes tax, followed by a so-called speculation tax targeting nonresidents and “satellite families” — a term associated with households where the breadwinner stays in Asia, while the spouse and children live in Vancouver.

Economists and statisticians, as well as the federal housing agency, took a more nuanced view that wealthy buyers from abroad played only a supporting role in the runup in prices. There were a host of factors fuelling the market: Vancouver’s rock-bottom property tax rate, the lack of a capital-gains tax on primary residences, a byzantine zoning and permitting regime that strangles the housing supply, and a local economy that from its early days has attracted speculators, be they gold prospectors, stock promoters or real estate opportunists.

But the real villains were a decade-plus stretch of historically low interest rates, a legacy of the 2008 financial crisis, and a Canadian propensity to borrow that had elevated property speculation to a national sport.

“It makes for a tempting narrative: them, not us,” Evan Siddall , then head of the CMHC, cautioned in a 2016 speech in Vancouver, pointing to evidence that Canadians were more likely to buy investment properties than foreigners. “The scapegoat is obvious: blame foreigners.”
The Chinese-style urban gate is a landmark in the city’s Chinatown.

Local and provincial policymakers parried accusations that they were discriminating against Asians, claiming they were being even-handed. “Targeting foreign owners and the one per cent who are driving up housing costs,” is how B.C.’s finance ministry justified the barrage of new taxes in 2018.

Those policies have ensured that people purchasing houses as an investment “are paying their fair share of taxes,” the provincial government said in a response to questions last month, saying the measures didn’t target people by country of origin. “The important difference is not by citizenship, but between people who work and pay taxes here and the people who do not.”

Yet perplexingly, the province exempted nonresident buyers in places such as Whistler, which has an even more acute affordability problem. In 2016 foreign buyers accounted for some 10 per cent of property transactions, according to local real estate agents. But in Whistler the foreigners are mostly Americans — not Chinese.

Particularly corrosive was the provincial government’s anti-money-laundering campaign which — dubiously but indelibly — linked the housing runup to dirty money. Asian wealth became synonymous with illicit wealth as shocking images emerged of Chinese gamblers hauling bags of cash into Vancouver casinos. Amid public outrage, the government initiated a public inquiry into money laundering and its impact on housing prices that’s still ongoing.

“It was sort of like a syndicated TV series,” Henry Yu, a University of British Columbia historian, told the public inquiry in February, testifying on patterns of racism in the province’s housing discourse. “I think I’ve seen this episode.”

It took a pandemic to expose the trope.


Foreign buyers accounted for less than one per cent of $15 billion in residential transactions in the city last year, according to government data, a byproduct of closed borders and a steep drop in immigration.

Yet with homes ever more out of reach, few are publicly acknowledging that perhaps the focus on Asian buyers was disproportionate. Asked about the role interest rates have played in the surge, a spokesman for the provincial government responded with an emailed statement that noted “the factors driving up house prices today are different” and that its policies had successfully reduced the presence of foreigners in property transactions since 2018.

For Ling, the Taiwan-born immigrant, it seems deeply unfair that a small group of wealthy individuals were used to stereotype the entire Asian community. But the shock of being abused and spat on last May galvanized her decision to report the incident and to continue to raise her voice.

“Saying that we’re so multicultural dismisses the problem — in Canada, we don’t want to talk about it,” she says. “Well, that’s privilege — the privilege of not paying attention to what’s been happening.”

Fantastical Jurassic Fossil Shows Crustacean Eaten by Squid Eaten by Shark

SCIENCE ALERT
11 MAY 2021

Sometime in the early Jurassic, an ancient squid-like creature speared a yummy lobster-like crustacean with its many hooked tentacles. Just as it began to dig into its meal, the eater became the eaten.

A much larger predator swooped in, tore a chunk out of the squid's soft middle and dashed off, leaving the leftovers of this three-way feeding fest sinking slowly to the bottom.

Roughly 180 million years later, the fossilized scene has been discovered in a quarry in Germany, and after close analysis, paleontologists now think they've figured out who was at the top of the food chain.

According to experts, the extinct squid-like cephalopod, known as a belemnite, was most probably killed by an ancient crocodile, shark, or other large predatory fish.

Whatever it was, the predator didn't stick around to finish its meal, likely because cephalopods have tough rostra - beaks that are hard, pointed and difficult to digest.

This means the hunter probably wasn't an ichthyosaur, even though fossils of these extinct marine reptiles suggest they were particularly skilled at picking around the hard areas of belemnites. Their stomach contents only show the mega-hooks found on belemnite tentacles and no other hard structures.

Fossilized stomachs of marine crocodiles and predatory fish, on the other hand, suggest these creatures gobbled everything down, swallowing both the mega-hooks and the hard beaks of squid.

Yet eating the whole squid isn't necessarily a good thing. A fossilized shark, also found in Germany from the Jurassic, was found with a whole pile of belemnite beaks in its stomach, and experts say these hard structures likely caused the shark's death. The diagram below shows the extreme blockage they created in the creature's stomach.

After some uncomfortable experiences, the authors suggest ancient sharks and crocs in the Jurassic learned to go after only the soft parts of their squid prey, choosing to drop the fins, rostrum, and mantle.

In the current fossil, for example, the belemnite has retained its rostrum and arms, but everything soft in between is gone.

"Remarkably, most of the belemnite soft parts between the arm crown and the calcitic rostrum are missing," the authors note.

"We suggest that this represents remains of a meal of a vertebrate predator, possibly of the Early Jurassic shark Hybodus hauffianus. This is remarkable, because it informs about the behavior of a cephalopod and a vertebrate predator."

A possible scenario explaining the fossilized remains has been illustrated below, showing a squid-like creature chewing on a crustacean while, in turn, a shark chews on it.

(Klug et al., Swiss J Palaeontol., 2021)

The team have classified their discovery as a 'leftover fall', which is sort of like a whale fall, except this one is caused by an ocean predator dropping all or part of its meal.

Once the uneaten prey sinks to the bottom, fewer scavengers and weaker currents make fossilization more likely.

The result is a 'pabulite', a term which the authors of the new study have coined to describe a fossilized leftover fall. It's a combination of the Latin word for food, pabulum, and the Greek word for stone, lithos.

Pabulites have been discovered numerous times over the years, and while solitary heads, fins and tails of ancient creatures might seem less valuable then a complete fossil, these incomplete remains can help us form a unique picture of the Jurassic food web.

'Living Fossil' Thought Extinct For 273 Million Years Found Thriving on Ocean Floor

SCIENCE ALERT
MAY 10, 2021

A symbiotic relationship between two marine lifeforms has just been discovered thriving at the bottom of the ocean, after disappearing from the fossil record for hundreds of millions of years.

Scientists have found non-skeletal corals growing from the stalks of marine animals known as crinoids, or sea lilies, on the floor of the Pacific Ocean, off the coasts of Honshu and Shikoku in Japan.

"These specimens represent the first detailed records and examinations of a recent syn vivo association of a crinoid (host) and a hexacoral (epibiont)," the researchers wrote in their paper, "and therefore analyses of these associations can shed new light on our understanding of these common Paleozoic associations."

During the Paleozoic era, crinoids and corals seem to have gotten along very well indeed. The seafloor fossil record is full of it, yielding countless examples of corals overgrowing crinoid stems to climb above the seafloor into the water column, to stronger ocean currents for filter-feeding.

Yet these benthic besties disappeared from the fossil record around 273 million years ago, after the specific crinoids and corals in question went extinct. Other species of crinoids and corals emerged in the Mesozoic, following the Permian-Triassic extinction - but never again have we seen them together in a symbiotic relationship.

Well, until now. At depths exceeding 100 meters (330 feet) below the ocean's surface, scientists have found two different species of coral - hexacorals of the genera Abyssoanthus, which is very rare, and Metridioidea, a type of sea anemone - growing from the stems of living Japanese sea lilies (Metacrinus rotundus).

The joint Polish-Japanese research team, led by paleontologist Mikołaj Zapalski of the University of Warsaw in Poland, first used stereoscopic microscopy to observe and photograph the specimens.

Then, they used non-destructive microtomography to scan the specimens to reveal their interior structures, and DNA barcoding to identify the species.

They found that the corals, which attached below the feeding fans of the crinoids, likely didn't compete with their hosts for food; and, being non-skeletal, likely didn't affect the flexibility of the crinoid stalks, although the anemone may have hindered movement of the host's cirri - thin strands that line the stalk.

It's also unclear what benefit the crinoids gain from a relationship with coral, but one interesting thing did emerge: unlike the Paleozoic corals, the new specimens did not modify the structure of the crinoids' skeleton.

This, the researchers said, can help explain the gap in the fossil record. The Paleozoic fossils of symbiotic corals and crinoids involve corals that have a calcite skeleton, such as Rugosa and Tabulata.

Fossils of soft-bodied organisms - such as non-skeletal corals - are rare. Zoantharia such as Abyssoanthus have no confirmed fossil record, and actiniaria such as Metridioidea (seen as a dry specimen in the image below) also are extremely limited.

If these corals don't modify the host, and leave no fossil record, perhaps they have had a long relationship with crinoids that has simply not been recorded.

This means the modern relationship between coral and crinoid could contain some clues as to Paleozoic interactions between coral and crinoid. There's evidence to suggest that zoantharians and rugose corals share a common ancestor, for instance.

The number of specimens recovered to date is small, but now that we know they are there, perhaps more work can be done to discover the history of this fascinating friendship.

"As both Actiniaria and Zoantharia have their phylogenetic roots deep in the Palaeozoic, and coral-crinoid associations were common among Palaeozoic Tabulate and Rugose corals, we can speculate that also Palaeozoic non-skeletal corals might have developed this strategy of settling on crinoids," the researchers wrote in their paper.

"The coral-crinoid associations, characteristic of Palaeozoic benthic communities, disappeared by the end of Permian, and this current work represents the first detailed examination of their rediscovery in modern seas."

The research has been published in Palaeogeography, Palaeoclimatology, Palaeoecology.
Shrunken head artifact used as prop in John Huston film revealed to be human

Tom Metcalfe

A grim artifact that had been on display for decades in a Georgia university has been authenticated as a human head taken from a slain enemy by an Amazonian warrior almost a century ago — and it is now on its way back to where it came from.

Researchers at Mercer University in Macon say their tests show that the shrunken head — called a tsantsa in Amazonian languages — is a genuine shrunken head made in a laborious ceremony of removing its skull and flesh, stitching shut its eyes and mouth, boiling it and then filling it with hot sand and stones.

In 2019, Mercer University repatriated the verified tsantsa to the Ecuadorian Consulate in Atlanta. It's not clear whether it has yet been returned to Ecuador, but the researchers said they hope it will ultimately be part of a collection, perhaps at a museum, where it will be treated properly.

"We wanted it to be viewed by people who could appreciate it in an appropriate context," said Mercer University chemist Adam Kiefer, a co-author of a study of the shrunken head published Monday in the journal Heritage Science.

"This is not an oddity — this is somebody's body, this is somebody's culture, and it's not ours," he said. "So from our perspective, repatriation was essential, and we were very lucky that our university supported this endeavor."

Shrunken heads were popular curios and keepsakes in some parts of the Western world in the 19th century, and many fakes were made to meet the demand — some of which were illicitly created from bodies taken from cemeteries and morgues. That led to justifiable concerns that the tsantsa at Mercer University may have also been fake.

Kiefer and his colleagues at Mercer, biologist Craig Byron and biomedical engineer Joanna Thomas, were tasked with verifying that the shrunken head was genuine after academics decided it could be of cultural importance and Ecuador's government asked whether it could be authenticated.

The researchers studied it using a variety of techniques, including computerized tomography, or CT, scans, which allowed them to reconstruct a three-dimensional model of the tsantsa both with and without its long hair. Thomas said the CT scans verified that the head underneath the hair had been cut open to remove the skull and then stitched up again as part of the ceremonial process that created it. The CT scans were also used to create a three-dimensional model to take its place in the university's collection.

Their tests showed that the shrunken head met 30 of the 32 criteria scientifically accepted for verifying authentic tsantsas, including the tiny hairs visible on its skin and in its nostrils, as well as its distinctive three-tiered hairstyle, which was characteristic of the peoples who then lived in the Ecuadorian Amazon region where it was from, Kiefer said.

The tsantsa at Mercer became part of the university's collection after the death in 2016 of a member of the faculty, biologist Jim Harrison, who acquired it during a trip into Ecuador's remote Amazon region in 1942 while serving in the military during World War II

Adam Kiefer Image: The tsantsa was stuffed with a local newspaper to protect it during its transport from Ecuador to the United States in 1942. 

Harrison wrote in a memoir that he had traded with local people for the tsantsa. "It was Indiana Jones," Kiefer said. "When this was collected, science was different, everything was new ... but almost 80 years later, we recognize its cultural importance, along with the science."

It's thought the ceremonial process of making tsantsas may have originated as a way to overcome a tradition of blood feuds among some peoples of the Amazon jungle; it seems to have been intended to trap the spirit of the slain warrior within the shrunken head so its supernatural power could be transferred to the community of the victor.

Curiously, Harrison's tsantsa also appeared as a movie prop in the 1979 John Huston film "Wise Blood," a version of a novel by the writer Flannery O'Connor, who had lived near Macon. It was glued onto a prop body for the movie, and the damage that was caused could be seen by the researchers.

Universities and museums now often try to repatriate many of the human remains that were once on display in archaeological and anthropological collections.

In the U.S., the Smithsonian Institution has been repatriating human remains and other culturally important objects since the 1980s, particularly to Native American communities. It has repatriated more than 6,000 objects, including several tsantsas that were sent in 1999 to representatives of the indigenous Shuar people in Ecuador and Peru.

Last year, the Pitt Rivers Museum at the University of Oxford in the United Kingdom removed a display of tsantsas that had been morbidly popular for decades.

"Visitors often referred to them as gruesome or disgusting or a freak show or gory," said Laura Van Broekhoven, the museum's director. "People were not understanding the more cultural meaning of the tsantsas ... so we were not doing a very good job of how we were curating the display."

The museum has been negotiating for four years with South American universities and indigenous groups to repatriate the tsantsas; any human remains and cultural objects acquired in the future will be dealt with under strict regulations the university has adopted, she said.

"We have to take things case by case," she said. "It's often a long process."

Schools spending millions on air purifiers often sold using overblown claims

By Lauren Weber and Christina Jewett, Kaiser Health News 

Last summer, Global Plasma Solutions wanted to test whether the company's air-purifying devices could kill Covid-19 virus particles, but could find only a lab using a chamber the size of a shoebox for its trials. 

In the company-funded study, the virus was blasted with 27,000 ions per cubic centimeter. The company said it found a 99% reduction of virus.

The report doesn't say how this reduction was measured, and in September, the company's founder incidentally mentioned that the devices being offered for sale would actually deliver a lot less ion power -- 13 times less -- into a full-sized room.

The company nonetheless used the shoebox results in marketing its device heavily to schools as something that could combat Covid in classrooms far, far larger than a shoebox.



School officials desperate to calm worried parents bought these devices and others with a flood of federal funds, installing them in more than 2,000 schools across 44 states, a KHN investigation found. They use the same technology — ionization, plasma and dry hydrogen peroxide — that the Lancet COVID-19 Commission recently deemed "often unproven" and potential sources of pollution themselves.

In the frenzy, schools are buying technology that academic air-quality experts warn can lull them into a false sense of security or even potentially harm kids. And schools often overlook the fact that their trusted contractors — typically engineering, HVAC or consulting firms — stand to earn big money from the deals, KHN found.

Academic experts are encouraging schools to pump in more fresh air and use tried-and-true filters, like HEPA, to capture the virus. Yet every ion- or hydroxyl-blasting air purifier sale strengthens a firm's next pitch: The device is doing a great job in the neighboring town.

"It's a self-fulfilling prophecy. The more people buy these technologies, the more they get legitimacy," said Jeffrey Siegel, a civil engineering professor at the University of Toronto. "It's really the complete wild west out there."

Marwa Zaatari, a member of the American Society of Heating, Refrigerating and Air-Conditioning Engineers' (ASHRAE) Epidemic Task Force, first compiled a list of schools and districts using such devices.

Schools have been "bombarded with persistent salespersons peddling the latest air and cleaning technologies, including those with minimal evidence to-date supporting safety and efficacy" according to a report released Thursday by the Center for Green Schools and ASHRAE.

Zaatari said she was particularly concerned that officials in New Jersey are buying thousands of devices made by another company that says they emit ozone, which can exacerbate asthma and harm developing lungs, according to decades of research.

"We're going to live in a world where the air quality in schools is worse after the pandemic, after all of this money," Zaatari said. "It's really sickening."

The sales race is fueled by roughly $193 billion in federal funds allocated to schools for teacher pay and safety upgrades — a giant fund that can be used to buy air cleaners. And Democrats are pushing for $100 billion more that could also be spent on air cleaners.

In April, Global Plasma Solutions said further tests show its devices inactivate Covid in the air and on surfaces in larger chambers. The company studies still use about twice the level of ions as its leaders have publicly said the devices can deliver, KHN found.

There is virtually no federal oversight or enforcement of safe air-cleaning technology. Only California bans air cleaners that emit a certain amount of ozone.

U.S. Rep. Robert "Bobby" Scott (D-Va.), chair of the House Committee on Labor and Education, said the federal government typically is not involved in local decisions of what products to buy, although he hopes for more federal guidance.

In the meantime, "these school systems are dealing with contractors providing all kinds of services," he said, "so you just have to trust them to get the best expert advice on what to do."

These go-between contractors — and the air cleaner companies themselves — have a stake in the sales. While their names might appear in school board records, their role in selling the device or commission from the deal is seldom made public, KHN found.

A LinkedIn job ad with the logo for one air purifier company, ActivePure Technology, which employs former Trump adviser Dr. Deborah Birx as its chief medical and science adviser, recruited salespeople this way: "Make Tons of Money with this COVID-killing Technology!!" The commission, the post said, is up to $900 per device.

"We have reps [who] made over 6-figures in 1 month selling to 1 school district," the ad says. "This could be the biggest opportunity you have seen!"

'A tiny bit of ozone'


Schools in New Jersey have a particularly easy time buying air cleaners called Odorox: A state education agency lists them on their group-purchasing commodity list, with a large unit selling for more than $5,100. Originally used in home restoration and mold remediation, the devices have become popular in New Jersey schools as the company says its products can inactivate Covid.

In Newark, administrators welcomed students back to class this month with more than 3,200 Odorox units, purchased with $7.5 million in federal funds, said Steven Morlino, executive director of Facilities Management for Newark Public Schools.

"I think parents feel pretty comfortable that their children are going to a safe environment," he said. "And so did the staff."

Environmental health and air-quality experts, though, are alarmed by the district's plan.

The Pyure company's Odorox devices are on California air-quality regulators' list of "potentially hazardous ozone generators sold as air purifiers" and cannot be sold in the state.

A company distributor's research shows that its Boss XL3 device pumps out as much as 77 parts per billion of ozone, a level that exceeds limits set by California lawmakers for the sale of indoor air cleaners and the EPA standard for ground-level ozone — a limit set to protect children from the well-documented harm of ozone to developing lungs.

That level exceeds the industry's self-imposed limit by more than 10 times and is "unacceptable," according to William Bahnfleth, an architectural engineering professor at Penn State who studies indoor air quality and leads the ASHRAE Epidemic Task Force.

Jean-Francois "JF" Huc, CEO of the Pyure company, pointed out that the study was done in a space smaller than they would recommend for such a powerful Odorox device. He cautioned that it was done that way to prove that home-restoration workers could be in the room with the device without violating work-safety rules.

"We provide very stringent operating guidelines around the size of room that our different devices should be put in," he said.

You can't see or smell ozone, but lungs treat it like a "foreign invader," said Michael Jerrett, who has studied its health effects as director of the UCLA Center for Occupational and Environmental Health.

Lung cells mount an immune-like response, which can trigger asthma complications and divert energy from normal lung function, he said. Chronic exposure has been linked to more emergency room visits and can even cause premature death. Once harmed, Jerrett said, children's lungs may not regain full function.

"Ozone is a very serious public health problem," Jerrett said.

Newark has some of the highest childhood asthma rates in the state, affecting one in four kids. Scholars have linked outdoor ozone levels in Newark to elevated childhood ER visits and asthma is the leading cause of school absenteeism there.

Adding ozone into the classroom is "just nightmarish," Siegel, of the University of Toronto, said.

Morlino said the district plans to monitor ozone levels in each classroom, based on the federal Occupational Safety and Health Administration level for working adults, which is 100 parts per billion.

"In our research of the product," he said, "we've determined it's within the guidelines the federal government produces."

While legal for healthy working adults, the work-safety standard should not apply to developing children, said Michael Kleinman, an air-quality researcher at the UC Irvine School of Medicine. "It's not a good device to be using in the presence of children," he said.

But the devices are going into schools throughout the state that will not be monitoring ozone levels, acknowledged Dave Matisoff, owner of Bio-Shine, a New Jersey-based distributor of Odorox. He said the main safeguard is informing schools about the appropriate-size room each device should be deployed to, a factor in ozone concentration.

Huc, the CEO, said his team has measured levels of ozone that are higher outdoors in Newark than inside — with his company's units running.

"There is a tiny bit of ozone that is introduced, but it's very, very low," he said. "And you get the benefit of the antimicrobial effect, you get the benefit of reduction of pathogens, which we've demonstrated in a number of studies, and you get the reduction of VOC [volatile organic compounds]."

Meanwhile, despite expert concerns, the devices continue to pop up in classrooms and school nurses' offices across the state, said Allen Barkkume, an industrial hygienist for the New Jersey teachers union.

He doesn't blame schools for buying them, as they're a lot less expensive than overhauling ventilation systems. Teachers often push for the devices in their classrooms, he said, as they see them in the nurses' offices and think it'll keep them safe. And superintendents are not well-versed in air quality's complex scientific concepts.

"Nothing sounds better than something that's cheap, quiet, small and easy to find, and we can stick them in every classroom," Barkkume said.


Tested in shoebox, sold for classrooms

While New York officials are "not permitting" the installation of ionization devices due to "potential negative health effects," schools across the state of New Jersey are installing ionizing devices.

Ten miles away from Newark in Montclair, New Jersey, parents have been raising hell over the new Global Plasma Solutions' ionizing devices in their children's classrooms. The company website promises a product that emits ions like those "created with energy from rushing water, crashing waves and even sunlight."

The devices emit positive and negative ions that are meant to help particles clump together, making them easier to filter out. The company says the ions can also reduce the viral particles that cause Covid-19.

But Justin Klabin, a building developer with a background in indoor air quality and two sons in the district, was not convinced.

He spent hours compiling scientific evidence. He created YouTube videos that painstakingly pick apart the ionizers' viability and helped organize a petition signed by dozens of parents warning the school board against the installation.

Even so, the district spent $635,900 on installing ionizers, which would go in classrooms serving more than 6,000 kids. The devices are often installed in ducts, an important consideration, the company founder Charles Waddell said, because the ions that are emitted lose their power after 60 seconds.

But the company's shoebox study and inflated ion blast numbers that helped sell the product last year leave a potential customer with little sense of how the device would perform in a classroom, Zaatari said.

"It's a high cost for nothing," Zaatari said. The company has sued her and another air-quality consultant for criticizing their devices. Of the pending case, Zaatari said it is a David-versus-Goliath situation, but she will not be deterred from speaking on behalf of children.

"Size of the [test] chamber has proved not to play a role in efficacy results but rather ion density," GPS spokesperson Kevin Boyle said in an email. The company notes by its Covid-inactivating test results that they "may include ... higher-than-average ion concentrations."

He also said the company is proud to meet the ASHRAE "zero ozone" certification.

Glenn Morrison, a professor of environmental science and engineering at the University of North Carolina, reviewed a March GPS study on a device combating the Covid virus in the air. The device appears to reduce virus concentrations, he said in an email, but noted it would not be very effective under normal building conditions, outside a test chamber. "A cheap portable HEPA filter would work many times better and have fewer side effects (possibly ozone or other unwanted chemistry)," he wrote.

Other parents joined Klabin's campaign, including Melanie Robbins, the mom of a kindergartener and a child in pre-K. Armed with her background in nonprofit advocacy, she reached out to experts. She and other parents spoke at local government meetings about their concerns.

In April, the superintendent told parents the school would turn off the devices, but parents say they haven't turned them all off.

"As far as I understand, the district has relied only on information from GPS, the manufacturer," Robbins said during a Montclair Board of Education meeting via Zoom on April 19. "This is like only listening to advice from Philip Morris as to whether smoking is safe or not."

Dan Daniello, of D&B Building Solutions, an HVAC contracting company, defended GPS products during the meeting. He said they are even used in the White House, a selling point the company has made repeatedly.

The catch: A GPS contractor installed its ionization technology in the East Wing of the White House after it was purchased in 2018 — before Covid emerged, according to GPS' Boyle. But the company was still using the White House logo as a marketing image on its website when KHN asked the White House about the advertising in April. It was taken down shortly thereafter.

Boyle said GPS was "recently informed that the White House logo may not be used for marketing purposes, and promptly complied."

The Montclair school district did not respond to requests for comment.

"I want to bang my head against the wall, it's so black-and-white," Robbins said. "Admit this is a poor purchase. The district got played."

Selling 'the Big Kahuna'


Academic air-quality experts agree on what's best for schools: More outside air pumped into classes, MERV 13 filters in heating systems and portable HEPA filters. The solution is time-tested and effective, they say. Yet as common commodities, like a pair of khaki pants, these items are not widely flogged by a sales force chasing big commissions.

After Covid hit, Tony Barron said the companies pitched air purifying technology nonstop to the Kansas district where he worked as a facility manager last fall.

Pressure came from inside the school as well. Teachers sent links for air cleaners they saw on the news. His superintendent had him meet with a friend who sold ionization products. He got constant calls, mail and email from mechanical engineering companies.

The hundreds of phone calls from air cleaner pitches were overwhelming, said Chris Crockett, director of facilities for Turner USD 202 in Kansas City, Kansas. While he wanted to trust the contractors he had worked with, he tested four products before deciding to spend several hundred thousand dollars.

"Custodial supply companies see the writing on the wall, that there's a lot of money out there," he said. "And then a lot of money is going to be spent on HVAC systems."

ActivePure says on its website that its air purifiers are in hundreds of schools. In a news release, the company said they were "sold through a nationwide network of several hundred franchises, 5,000 general contractors/HVAC specialists and thousands of individual distributors."

Enviro Technology Pros, founded in January, is one company pitching ActivePure to HVAC contractors. In a YouTube video, the founders said contractors can make $950 for each air-cleaning device sold, and some dealers can make up to $30,000 a month. Citing the bounty of the billions in federal relief, another video touted ready-made campaigns to target school principals directly.

After KHN asked ActivePure for comment, the Enviro Technology Pros YouTube videos about ActivePure were no longer accessible publicly.

ActivePure did not respond to requests for comment but has said its devices are effective and one is validated by the Food and Drug Administration.

An Enviro Technology Pros founder, Rod Norman, told KHN the company was asked to take the posts down by Vollara, a company related to ActivePure. He called sales to schools "the big kahuna."

Shortly after he spoke with KHN, the website for his own company was taken down.

In an Instagram post that also disappeared, the company had asked: "4000 classrooms protected why not your kids?"

Correction: This article has been revised to reflect that an Odorox distributor, not Pyure, commissioned the ozone test on a Boss XL3. And the article was revised to reflect that Pyure CEO Jean-Francois "JF" Huc said his company provides stringent operating guidelines for use of the company's air purifiers but did not acknowledge that school staffers are often not warned about the problems they could face if a too-powerful device is used in a too-small room

Escalating violence in Jerusalem has Winnipeg's Palestinian and Jewish communities on edge

Duration: 02:14 


Idris Elbakri, a Palestinian Canadian who lives in Winnipeg, grew up in Jerusalem. He was at the Al-Aqsa Mosque compound, which has been a flashpoint in the latest conflict in the region, just a few weeks ago, after travelling to Jerusalem for a family emergency.
