At the end of June, the United States government announced that it had secured the entire supply of remdesivir, an antiviral drug that shortens hospital stays for COVID-19 patients, until September.

In March, there were reports that Donald Trump’s administration tried to buy a German company working on a COVID-19 vaccine in order to secure the entire supply for the U.S. A group formed by France, Germany, Italy and the Netherlands struck a deal in the past few weeks to secure 400 million doses of AstraZeneca’s potential vaccine, although other countries are also encouraged to join the group on the same terms. Whether poor countries could afford the terms is another question.

It certainly doesn’t seem that “we’re all in this together” — it’s looking more and more like a dog-eat-dog world. The group that’s most likely to be eaten are those living in low- and middle-income countries (LMICs). Gilead, the maker of remdesivir, has licence agreements with manufacturers to supply remdesivir in 127 LMICs, but those agreements exclude large middle-income countries such as Brazil, China and Mexico.

Vaccine nationalism

Gavi, the Vaccine Alliance is creating a facility that will enter into advance purchase agreements with pharmaceutical companies guaranteeing the purchase of any eventual vaccines. But this proposal has generated significant global concerns about its impact on equitable access for populations, especially in developing countries. Under the agreement, rich countries will get the first crack at enough vaccine to cover 20 per cent of their population, and only then will poorer countries be guaranteed the vaccine — and only for their highest priority populations.

The Serum Institute of India has entered a licensing agreement with AstraZeneca to acquire one billion doses of AstraZeneca’s potential COVID-19 vaccine for LMICs, with a commitment to provide 400 million doses before the end of 2020. But the terms and conditions of the agreement are unknown, including the price and the number of countries eligible for supply.

South Africa has started a trial of the vaccine being developed by the University of Oxford in partnership with AstraZeneca to try to avoid being left behind in the race to secure a supply. Helen Rees, chairwoman of the South African Health Products Regulatory Authority, said in a briefing: “That debate about vaccine nationalism now is very critical…There has to be an equitable distribution of vaccines. It cannot be all for some and none for many others.”

Costs, supply and control

The cost of remdesivir in the U.S. is going to be US$390 per vial, which would amount to US$2,340 per five-day treatment course. It’s estimated that remdesivir could be made for under US$1 a dose, less than a quarter of one per cent of what Gilead will be charging. At Gilead’s price, the company could earn well over US$2 billion in the first year the drug is on sale. The cost will hopefully be much lower in countries that are the recipients of Gilead’s licences, but what about the excluded countries? At this point, no one knows. That includes Canada.

Gilead is in the process of submitting an application for approval of remdesivir to Health Canada and, according to Health Canada, the review will be conducted under expedited timelines due to the seriousness of COVID-19. Of course, under the new deal between the U.S. and Gilead, there won’t be any remdesivir for Canada to buy until the end of September. Canada could issue a compulsory licence to allow generic companies to make remdesivir, but currently that authority expires at the end of September so we may be stuck with Gilead as the only supplier.

Gilead controls the supply of remdesivir because it holds the patent on the drug. When Jonas Salk, the inventor of the polio vaccine, was asked if he was going to patent it, his famous response was: “There is no patent, could you patent the sun?” In other words, the vaccine was a public good meant to be used by everyone.

Gilead obviously doesn’t hold the same view about remdesivir, despite the fact that U.S. taxpayers contributed at least $70.5 million to developing the drug.

Canada’s role

What should Canada be doing about all of this? How is the federal government going to ensure that Canadians have access to COVID-19 treatments and vaccines?

Right now, we don’t have the capability to manufacture a vaccine in the country. Connaught Laboratories, which was instrumental in helping to develop the polio vaccine, used to be able to make vaccines, but it was sold off by the federal government back in 1989 to a French firm.

The group that’s most at risk for being unable to access new COVID-19 treatments are those living in low- and middle-income countries. (Pixabay)

The federal government should be looking at setting up a Crown corporation to ensure a domestic supply of critical drugs and vaccines at reasonable prices. Until that can be done, the government should extend the compulsory licensing provision in its emergency legislation so that generic companies can be allowed to make future patented therapies at lower costs.

But Canada needs to do much more. When Prime Minister Justin Trudeau was first elected back in 2015, he proclaimed that “Canada is back” in international relations. Despite this promise, Canada has yet to commit to ensuring that any COVID-19 research that is done with Canadian money has to guarantee that products will be available at affordable prices in low- and middle-income countries.

Canada has not signed on to the recently established COVID-19 technology access pool being sponsored by the World Health Organization that is designed to help ensure that COVID-19 health technology-related knowledge, intellectual property and data is voluntarily shared.

Canada is not back; it’s missing in action both domestically and internationally.

In 2017-2020, Joel Lexchin received payments for being on a panel at the American Diabetes Association, for talks at the Toronto Reference Library, for writing a brief in an action for side effects of a drug for Michael F. Smith, Lawyer and a second brief on the role of promotion in generating prescriptions for Goodmans LLP and from the Canadian Institutes of Health Research for presenting at a workshop on conflict-of-interest in clinical practice guidelines.

Fauci Deputy Warned Him Against Vaccine Mandates: Email

Authored by Zachary Stieber via The Epoch Times (emphasis ours),

Mandating COVID-19 vaccination was a mistake due to ethical and other concerns, a top government doctor warned Dr. Anthony Fauci after Dr. Fauci promoted mass vaccination.

Coercing or forcing people to take a vaccine can have negative consequences from a biological, sociological, psychological, economical, and ethical standpoint and is not worth the cost even if the vaccine is 100% safe,” Dr. Matthew Memoli, director of the Laboratory of Infectious Diseases clinical studies unit at the U.S. National Institute of Allergy and Infectious Diseases (NIAID), told Dr. Fauci in an email.

“A more prudent approach that considers these issues would be to focus our efforts on those at high risk of severe disease and death, such as the elderly and obese, and do not push vaccination on the young and healthy any further.”

Employing that strategy would help prevent loss of public trust and political capital, Dr. Memoli said.

The email was sent on July 30, 2021, after Dr. Fauci, director of the NIAID, claimed that communities would be safer if more people received one of the COVID-19 vaccines and that mass vaccination would lead to the end of the COVID-19 pandemic.

“We’re on a really good track now to really crush this outbreak, and the more people we get vaccinated, the more assuredness that we’re going to have that we’re going to be able to do that,” Dr. Fauci said on CNN the month prior.

Dr. Memoli, who has studied influenza vaccination for years, disagreed, telling Dr. Fauci that research in the field has indicated yearly shots sometimes drive the evolution of influenza.

Vaccinating people who have not been infected with COVID-19, he said, could potentially impact the evolution of the virus that causes COVID-19 in unexpected ways.

“At best what we are doing with mandated mass vaccination does nothing and the variants emerge evading immunity anyway as they would have without the vaccine,” Dr. Memoli wrote. “At worst it drives evolution of the virus in a way that is different from nature and possibly detrimental, prolonging the pandemic or causing more morbidity and mortality than it should.”

The vaccination strategy was flawed because it relied on a single antigen, introducing immunity that only lasted for a certain period of time, Dr. Memoli said. When the immunity weakened, the virus was given an opportunity to evolve.

Some other experts, including virologist Geert Vanden Bossche, have offered similar views. Others in the scientific community, such as U.S. Centers for Disease Control and Prevention scientists, say vaccination prevents virus evolution, though the agency has acknowledged it doesn’t have records supporting its position.

Other Messages

Dr. Memoli sent the email to Dr. Fauci and two other top NIAID officials, Drs. Hugh Auchincloss and Clifford Lane. The message was first reported by the Wall Street Journal, though the publication did not publish the message. The Epoch Times obtained the email and 199 other pages of Dr. Memoli’s emails through a Freedom of Information Act request. There were no indications that Dr. Fauci ever responded to Dr. Memoli.

Later in 2021, the NIAID’s parent agency, the U.S. National Institutes of Health (NIH), and all other federal government agencies began requiring COVID-19 vaccination, under direction from President Joe Biden.

In other messages, Dr. Memoli said the mandates were unethical and that he was hopeful legal cases brought against the mandates would ultimately let people “make their own healthcare decisions.”

“I am certainly doing everything in my power to influence that,” he wrote on Nov. 2, 2021, to an unknown recipient. Dr. Memoli also disclosed that both he and his wife had applied for exemptions from the mandates imposed by the NIH and his wife’s employer. While her request had been granted, his had not as of yet, Dr. Memoli said. It’s not clear if it ever was.

According to Dr. Memoli, officials had not gone over the bioethics of the mandates. He wrote to the NIH’s Department of Bioethics, pointing out that the protection from the vaccines waned over time, that the shots can cause serious health issues such as myocarditis, or heart inflammation, and that vaccinated people were just as likely to spread COVID-19 as unvaccinated people.

He cited multiple studies in his emails, including one that found a resurgence of COVID-19 cases in a California health care system despite a high rate of vaccination and another that showed transmission rates were similar among the vaccinated and unvaccinated.

Dr. Memoli said he was “particularly interested in the bioethics of a mandate when the vaccine doesn’t have the ability to stop spread of the disease, which is the purpose of the mandate.”

The message led to Dr. Memoli speaking during an NIH event in December 2021, several weeks after he went public with his concerns about mandating vaccines.

“Vaccine mandates should be rare and considered only with a strong justification,” Dr. Memoli said in the debate. He suggested that the justification was not there for COVID-19 vaccines, given their fleeting effectiveness.

Julie Ledgerwood, another NIAID official who also spoke at the event, said that the vaccines were highly effective and that the side effects that had been detected were not significant. She did acknowledge that vaccinated people needed boosters after a period of time.

The NIH, and many other government agencies, removed their mandates in 2023 with the end of the COVID-19 public health emergency.

A request for comment from Dr. Fauci was not returned. Dr. Memoli told The Epoch Times in an email he was “happy to answer any questions you have” but that he needed clearance from the NIAID’s media office. That office then refused to give clearance.

Dr. Jay Bhattacharya, a professor of health policy at Stanford University, said that Dr. Memoli showed bravery when he warned Dr. Fauci against mandates.

“Those mandates have done more to demolish public trust in public health than any single action by public health officials in my professional career, including diminishing public trust in all vaccines.” Dr. Bhattacharya, a frequent critic of the U.S. response to COVID-19, told The Epoch Times via email. “It was risky for Dr. Memoli to speak publicly since he works at the NIH, and the culture of the NIH punishes those who cross powerful scientific bureaucrats like Dr. Fauci or his former boss, Dr. Francis Collins.”

Trump "Clearly Hasn't Learned From His COVID-Era Mistakes", RFK Jr. Says

Authored by Jeff Louderback via The Epoch Times (emphasis ours),

President Joe Biden claimed that COVID vaccines are now helping cancer patients during his State of the Union address on March 7, but it was a response on Truth Social from former President Donald Trump that drew the ire of independent presidential candidate Robert F. Kennedy Jr.

During the address, President Biden said: “The pandemic no longer controls our lives. The vaccines that saved us from COVID are now being used to help beat cancer, turning setback into comeback. That’s what America does.”

President Trump wrote: “The Pandemic no longer controls our lives. The VACCINES that saved us from COVID are now being used to help beat cancer—turning setback into comeback. YOU’RE WELCOME JOE. NINE-MONTH APPROVAL TIME VS. 12 YEARS THAT IT WOULD HAVE TAKEN YOU.”

An outspoken critic of President Trump’s COVID response, and the Operation Warp Speed program that escalated the availability of COVID vaccines, Mr. Kennedy said on X, formerly known as Twitter, that “Donald Trump clearly hasn’t learned from his COVID-era mistakes.”

“He fails to recognize how ineffective his warp speed vaccine is as the ninth shot is being recommended to seniors. Even more troubling is the documented harm being caused by the shot to so many innocent children and adults who are suffering myocarditis, pericarditis, and brain inflammation,” Mr. Kennedy remarked.

“This has been confirmed by a CDC-funded study of 99 million people. Instead of bragging about its speedy approval, we should be honestly and transparently debating the abundant evidence that this vaccine may have caused more harm than good.

“I look forward to debating both Trump and Biden on Sept. 16 in San Marcos, Texas.”

Mr. Kennedy announced in April 2023 that he would challenge President Biden for the 2024 Democratic Party presidential nomination before declaring his run as an independent last October, claiming that the Democrat National Committee was “rigging the primary.”

Since the early stages of his campaign, Mr. Kennedy has generated more support than pundits expected from conservatives, moderates, and independents resulting in speculation that he could take votes away from President Trump.

Many Republicans continue to seek a reckoning over the government-imposed pandemic lockdowns and vaccine mandates.

President Trump’s defense of Operation Warp Speed, the program he rolled out in May 2020 to spur the development and distribution of COVID-19 vaccines amid the pandemic, remains a sticking point for some of his supporters.

Operation Warp Speed featured a partnership between the government, the military, and the private sector, with the government paying for millions of vaccine doses to be produced.

President Trump released a statement in March 2021 saying: “I hope everyone remembers when they’re getting the COVID-19 Vaccine, that if I wasn’t President, you wouldn’t be getting that beautiful ‘shot’ for 5 years, at best, and probably wouldn’t be getting it at all. I hope everyone remembers!”

President Trump said about the COVID-19 vaccine in an interview on Fox News in March 2021: “It works incredibly well. Ninety-five percent, maybe even more than that. I would recommend it, and I would recommend it to a lot of people that don’t want to get it and a lot of those people voted for me, frankly.

“But again, we have our freedoms and we have to live by that and I agree with that also. But it’s a great vaccine, it’s a safe vaccine, and it’s something that works.”

On many occasions, President Trump has said that he is not in favor of vaccine mandates.

An environmental attorney, Mr. Kennedy founded Children’s Health Defense, a nonprofit that aims to end childhood health epidemics by promoting vaccine safeguards, among other initiatives.

Last year, Mr. Kennedy told podcaster Joe Rogan that ivermectin was suppressed by the FDA so that the COVID-19 vaccines could be granted emergency use authorization.

He has criticized Big Pharma, vaccine safety, and government mandates for years.

Since launching his presidential campaign, Mr. Kennedy has made his stances on the COVID-19 vaccines, and vaccines in general, a frequent talking point.

“I would argue that the science is very clear right now that they [vaccines] caused a lot more problems than they averted,” Mr. Kennedy said on Piers Morgan Uncensored last April.

“And if you look at the countries that did not vaccinate, they had the lowest death rates, they had the lowest COVID and infection rates.”

Additional data show a “direct correlation” between excess deaths and high vaccination rates in developed countries, he said.

President Trump and Mr. Kennedy have similar views on topics like protecting the U.S.-Mexico border and ending the Russia-Ukraine war.

COVID-19 is the topic where Mr. Kennedy and President Trump seem to differ the most.

Former President Donald Trump intended to “drain the swamp” when he took office in 2017, but he was “intimidated by bureaucrats” at federal agencies and did not accomplish that objective, Mr. Kennedy said on Feb. 5.

Speaking at a voter rally in Tucson, where he collected signatures to get on the Arizona ballot, the independent presidential candidate said President Trump was “earnest” when he vowed to “drain the swamp,” but it was “business as usual” during his term.

John Bolton, who President Trump appointed as a national security adviser, is “the template for a swamp creature,” Mr. Kennedy said.

Scott Gottlieb, who President Trump named to run the FDA, “was Pfizer’s business partner” and eventually returned to Pfizer, Mr. Kennedy said.

Mr. Kennedy said that President Trump had more lobbyists running federal agencies than any president in U.S. history.

“You can’t reform them when you’ve got the swamp creatures running them, and I’m not going to do that. I’m going to do something different,” Mr. Kennedy said.

During the COVID-19 pandemic, President Trump “did not ask the questions that he should have,” he believes.

President Trump “knew that lockdowns were wrong” and then “agreed to lockdowns,” Mr. Kennedy said.

He also “knew that hydroxychloroquine worked, he said it,” Mr. Kennedy explained, adding that he was eventually “rolled over” by Dr. Anthony Fauci and his advisers.

MaryJo Perry, a longtime advocate for vaccine choice and a Trump supporter, thinks votes will be at a premium come Election Day, particularly because the independent and third-party field is becoming more competitive.

Ms. Perry, president of Mississippi Parents for Vaccine Rights, believes advocates for medical freedom could determine who is ultimately president.

She believes that Mr. Kennedy is “pulling votes from Trump” because of the former president’s stance on the vaccines.

“People care about medical freedom. It’s an important issue here in Mississippi, and across the country,” Ms. Perry told The Epoch Times.

“Trump should admit he was wrong about Operation Warp Speed and that COVID vaccines have been dangerous. That would make a difference among people he has offended.”

President Trump won’t lose enough votes to Mr. Kennedy about Operation Warp Speed and COVID vaccines to have a significant impact on the election, Ohio Republican strategist Wes Farno told The Epoch Times.

President Trump won in Ohio by eight percentage points in both 2016 and 2020. The Ohio Republican Party endorsed President Trump for the nomination in 2024.

“The positives of a Trump presidency far outweigh the negatives,” Mr. Farno said. “People are more concerned about their wallet and the economy.

“They are asking themselves if they were better off during President Trump’s term compared to since President Biden took office. The answer to that question is obvious because many Americans are struggling to afford groceries, gas, mortgages, and rent payments.

“America needs President Trump.”

Multiple national polls back Mr. Farno’s view.

As of March 6, the RealClearPolitics average of polls indicates that President Trump has 41.8 percent support in a five-way race that includes President Biden (38.4 percent), Mr. Kennedy (12.7 percent), independent Cornel West (2.6 percent), and Green Party nominee Jill Stein (1.7 percent).

A Pew Research Center study conducted among 10,133 U.S. adults from Feb. 7 to Feb. 11 showed that Democrats and Democrat-leaning independents (42 percent) are more likely than Republicans and GOP-leaning independents (15 percent) to say they have received an updated COVID vaccine.

The poll also reported that just 28 percent of adults say they have received the updated COVID inoculation.

The peer-reviewed multinational study of more than 99 million vaccinated people that Mr. Kennedy referenced in his X post on March 7 was published in the Vaccine journal on Feb. 12.

It aimed to evaluate the risk of 13 adverse events of special interest (AESI) following COVID-19 vaccination. The AESIs spanned three categories—neurological, hematologic (blood), and cardiovascular.

The study reviewed data collected from more than 99 million vaccinated people from eight nations—Argentina, Australia, Canada, Denmark, Finland, France, New Zealand, and Scotland—looking at risks up to 42 days after getting the shots.

Three vaccines—Pfizer and Moderna’s mRNA vaccines as well as AstraZeneca’s viral vector jab—were examined in the study.

Researchers found higher-than-expected cases that they deemed met the threshold to be potential safety signals for multiple AESIs, including for Guillain-Barre syndrome (GBS), cerebral venous sinus thrombosis (CVST), myocarditis, and pericarditis.

A safety signal refers to information that could suggest a potential risk or harm that may be associated with a medical product.

The study identified higher incidences of neurological, cardiovascular, and blood disorder complications than what the researchers expected.

President Trump’s role in Operation Warp Speed, and his continued praise of the COVID vaccine, remains a concern for some voters, including those who still support him.

Krista Cobb is a 40-year-old mother in western Ohio. She voted for President Trump in 2020 and said she would cast her vote for him this November, but she was stunned when she saw his response to President Biden about the COVID-19 vaccine during the State of the Union address.

I love President Trump and support his policies, but at this point, he has to know they [advisers and health officials] lied about the shot,” Ms. Cobb told The Epoch Times.

“If he continues to promote it, especially after all of the hearings they’ve had about it in Congress, the side effects, and cover-ups on Capitol Hill, at what point does he become the same as the people who have lied?” Ms. Cobb added.

“I think he should distance himself from talk about Operation Warp Speed and even admit that he was wrong—that the vaccines have not had the impact he was told they would have. If he did that, people would respect him even more.”

Scientists at The Universities of Manchester and Oxford have developed an AI framework that can identify and track new and concerning COVID-19 variants and could help with other infections in the future.

The framework combines dimension reduction techniques and a new explainable clustering algorithm called CLASSIX, developed by mathematicians at The University of Manchester. This enables the quick identification of groups of viral genomes that might present a risk in the future from huge volumes of data.

The study, presented this week in the journal PNAS, could support traditional methods of tracking viral evolution, such as phylogenetic analysis, which currently require extensive manual curation.

Roberto Cahuantzi, a researcher at The University of Manchester and first and corresponding author of the paper, said: “Since the emergence of COVID-19, we have seen multiple waves of new variants, heightened transmissibility, evasion of immune responses, and increased severity of illness.

“Scientists are now intensifying efforts to pinpoint these worrying new variants, such as alpha, delta and omicron, at the earliest stages of their emergence. If we can find a way to do this quickly and efficiently, it will enable us to be more proactive in our response, such as tailored vaccine development and may even enable us to eliminate the variants before they become established.”

Like many other RNA viruses, COVID-19 has a high mutation rate and short time between generations meaning it evolves extremely rapidly. This means identifying new strains that are likely to be problematic in the future requires considerable effort.

Currently, there are almost 16 million sequences available on the GISAID database (the Global Initiative on Sharing All Influenza Data), which provides access to genomic data of influenza viruses.

Mapping the evolution and history of all COVID-19 genomes from this data is currently done using extremely large amounts of computer and human time.

The described method allows automation of such tasks. The researchers processed 5.7 million high-coverage sequences in only one to two days on a standard modern laptop; this would not be possible for existing methods, putting identification of concerning pathogen strains in the hands of more researchers due to reduced resource needs.

Thomas House, Professor of Mathematical Sciences at The University of Manchester, said: “The unprecedented amount of genetic data generated during the pandemic demands improvements to our methods to analyse it thoroughly. The data is continuing to grow rapidly but without showing a benefit to curating this data, there is a risk that it will be removed or deleted.

“We know that human expert time is limited, so our approach should not replace the work of humans all together but work alongside them to enable the job to be done much quicker and free our experts for other vital developments.”

The proposed method works by breaking down genetic sequences of the COVID-19 virus into smaller “words” (called 3-mers) represented as numbers by counting them. Then, it groups similar sequences together based on their word patterns using machine learning techniques.

Stefan Güttel, Professor of Applied Mathematics at the University of Manchester, said: “The clustering algorithm CLASSIX we developed is much less computationally demanding than traditional methods and is fully explainable, meaning that it provides textual and visual explanations of the computed clusters.”

Roberto Cahuantzi added: “Our analysis serves as a proof of concept, demonstrating the potential use of machine learning methods as an alert tool for the early discovery of emerging major variants without relying on the need to generate phylogenies.

“Whilst phylogenetics remains the ‘gold standard’ for understanding the viral ancestry, these machine learning methods can accommodate several orders of magnitude more sequences than the current phylogenetic methods and at a low computational cost.”
