Renowned scientist Frank Plummer has died



The former scientific director of Canada’s National Microbiology Laboratory in Winnipeg who had experimental brain surgery to battle alcoholism has died.

Dr. Frank Plummer, a world-renowned microbiologist and infectious-disease expert, was 67.

“He was a scientific maverick,” Theresa Tam, Canada’s chief public health officer, tweeted on Tuesday.

Plummer was a mentor, she said, who helped set up and make the national laboratory in Winnipeg a world-class institution.

Plummer was at the helm of the lab during the SARS, influenza and H1N1 epidemics, as well as during the development of an Ebola vaccine.

Prior to his time at the lab, Plummer’s research shaped public health policy around the world.


He built a world-class research operation in Kenya, where he observed a particular group of women who had a natural immunity to HIV-1.

That discovery provided important information for HIV vaccine and drug development.

“He was admired and regarded highly by academics and researchers around the world, and his legacy of seeking to develop an HIV vaccine remains one of the landmarks of infectious disease prevention,” University of Manitoba president David Barnard said in a statement.

“His contributions have had a cumulative global impact on saving the lives of tens of thousands of people for decades and also improving the lives of HIV positive people around the world,” added Digvir Jayas, the university’s vice-president of research.

‘He was a proud Winnipegger and a proud Canadian’

Plummer was named an Officer of the Order of Canada in 2006 and a member of the Order of Manitoba three years later.

He received numerous prestigious awards throughout his career, including the Flavelle Medal from the Royal Society of Canada in 2018 for his contributions to biological science.

Plummer had recently shared his own battle with alcoholism.

In an article he wrote for Toronto’s Sunnybrook Health Sciences Centre, Plummer explained how he began to drink scotch to “to celebrate, relax and deal with stress, anxiety, disappointment and grief.”

After decades of drinking, attempts at quitting and a liver transplant, Plummer decided to get experimental treatment using deep brain stimulation in 2018.

“Having committed my career to medical science and human health I saw this study as one more way to make a contribution – this time, literally using my brain!” Plummer wrote.

Keith Fowke, head of medical microbiology and infectious diseases at the University of Manitoba, was a grad student under Plummer’s tutelage when they made the major discovery in Kenya. They later became close friends and colleagues.

Fowke said as a scientist or a research participant, Plummer always wanted to help people.

“He was always focused on truth and knowledge and making the world a better place,” Fowke said.

Fowke described his friend as warm and kind. He called Plummer a loving father and husband who enjoyed having his friends over for dinner.

“He wanted everyone to know he was a proud Winnipegger and a proud Canadian, and that all of us can make important globally significant contributions.”

InnovationRx: Stretching Monkeypox Vaccine Doses; Plus, Omicron Subvariant Boosters – Forbes



InnovationRx is your weekly digest of healthcare news. To get it in your inbox, subscribe here.

As the U.S. continues to face a rise in monkeypox cases (nearly 9,500 cases as of Tuesday), the FDA has OKed a new dosing strategy to stretch vaccine supplies. Bavarian Nordic’s Jynneos vaccine was originally approved by the FDA for a full dose to be administered subcutaneously, meaning underneath the skin into the fat of the arm. On Tuesday, the FDA issued an emergency use authorization that allows health workers to inject one-fifth of a normal dose intradermally, meaning into the skin.

But experts tell Forbes that this new method poses challenges for the vaccine rollout: there is limited data supporting the strategy and most healthcare workers have experience giving intradermal injections. This method could also produce more side effects, like swelling and itching at the injection site, compared to the standard dose, according to Dr. Jay Varma, a professor at Weill Cornell Medicine. Though Varma also said he thinks the new approach is the best one “given the vaccine supply shortage.”

Coronavirus Updates

Pfizer and BioNTech have completed clinical trials for vaccines that include specific protection against the original omicron variant. Now the two companies have begun testing for vaccines specific to the BA.4 and BA.5 Omicron subvariants, which are the fastest spreading variants of Covid-19 in the United States. Manufacturing for the new vaccines has already begun, and could be rolled out as early as October pending regulatory approvals. That’s good news as we approach the fall and winter, which have been the times of year where Covid spread is at its highest. Competitor Moderna has also begun testing an omicron specific booster, but the FDA has not yet authorized any Omicron-specific vaccines.

Polio largely vanished thanks to vaccines. So why is it now back in more countries? – CBC News



Polio, a potentially disabling virus that’s long been forgotten in many parts of the world, is now circulating in parts of the U.S. and U.K., on the heels of an outbreak in Israel — prompting health officials to launch vaccination campaigns to ensure the public is protected.

Even in Canada, a country free of polio for the last two decades, medical experts say it’s a wake-up call that the virus still poses a threat to anyone who remains unvaccinated, given polio’s ability to spread through global travel networks and wastewater systems.

On Wednesday, British health authorities announced they will offer a polio booster dose to children aged one to nine in London, after finding evidence the virus has been spreading in multiple regions of the capital. Britain’s Health Security Agency said polio virus samples were found in sewage water from eight boroughs of London, but there were no confirmed infections.

Still, the agency’s analysis showed transmission has likely “gone beyond a close network of a few individuals.”

“We know the areas in London where the poliovirus is being transmitted have some of the lowest vaccination rates,” said Dr. Vanessa Saliba, a consultant epidemiologist at the U.K. Health Security Agency.

100s could be infected with polio in New York, health officials say

A health official in New York State says hundreds of people could be infected with the polio virus.

The agency said it was working closely with health authorities in the U.S. and Israel, as well as the World Health Organization, to investigate the links between polio viruses detected in those two countries. 

In July, Israel announced a recent outbreak of polio infections appeared to be under control, after multiple people became infected, including a Jerusalem girl who was paralyzed and now requires rehabilitation, according to the Jerusalem Post.

More recently, in the state of New York, one unvaccinated young adult suffered paralysis after a polio infection in Rockland County — an area known for low vaccination rates — which marked the first case reported in the U.S. in nearly a decade. 

Vaccination campaigns are now underway as samples of the virus were also detected in the wastewater of both Rockland and another county, just north of New York City. Officials also say hundreds more people may already be infected.

“The scope may be even much larger than we can even fathom or imagine,” said New York-based immunologist Dr. Purvi Parikh.

“Because vaccines have become the victim of their own success, we don’t see it — so we may not even realize what the spread of polio is, because for the majority of us who are vaccinated, it doesn’t really [affect] us.”

Outbreaks do still happen in certain countries

Before mass vaccination campaigns largely wiped out polio from circulation in higher-income countries like Canada between the 1950s and early 1990s, the virus was known for sparking outbreaks and striking children, causing paralysis or death in some cases.

Even now, war, poverty, and social unrest make it difficult to achieve eradication in many countries around the world. Outbreaks remain common in Afghanistan, Pakistan, and parts of Africa.

Parikh said polio cases aren’t entirely a surprise in any community where vaccination rates are lower, either due to anti-vaccine sentiments or disruptions to routine immunizations during the COVID-19 pandemic.

“Now the concern is, some of these infectious diseases that we haven’t seen in nearly decades may actually come back and pose to be a problem,” she said.

Part of the challenge in wiping polio out around the world actually comes from the vaccination approach used in certain regions. While higher-income countries now use an inactivated poliovirus vaccine given as a traditional shot, others rely on a weakened poliovirus that’s easy to administer by mouth.

Both types of vaccines helped curb global transmission and, crucially, neither one is capable of giving someone a case of symptomatic polio.

However, since the oral version winds up in the stomach, it’s eventually flushed out of the body into wastewater systems — where, over time, the virus can evolve back into a form that’s able to cause disease.

“So if you have a shedding of that particular virus and transmission of that in a community, it can cause a polio outbreak,” said Dr. Isaac Bogoch, an infectious diseases specialist with the University Health Network in Toronto.

“And in fact, if you look at many parts of the world, there have been small outbreaks of vaccine-derived polio.”

‘Polio is only a plane trip away’

Lab testing conducted on the case in New York, for instance, linked the virus samples to transmission from someone who’d received the oral vaccine, which hasn’t been used in the U.S. since 2000. “This suggests that the virus may have originated in a location outside of the U.S. where [the oral vaccine] is administered,” officials said.

In London, out of more than 100 polio samples identified in sewage, most were vaccine-like virus, according to the UK Health Security Agency, while others had enough mutations to be more like “wild” polio that can cause serious health impacts.

Global travel between countries with high rates of polio transmission and regions with lagging vaccination rates could pose a problem going forward, said Wes Hazlitt, a Winnipeg polio survivor, advocate, and president of the Post-Polio Network in Manitoba.

“Polio,” he added, “is only a plane trip away.”

Another challenge in tackling outbreaks stems from this virus’s ability to spread undetected, experts say, with most people unaware they’re even infected — leaving countries vulnerable to slow-growing outbreaks before any patients show up with major disease and paralysis.

“Most people will have no symptoms or mild symptoms, but about one in 200 or so will have significant symptoms,” Bogoch said.

Under-vaccinated communities remain at risk

So when it comes to experiencing a future polio outbreak, how at risk is Canada? That all depends on vaccination rates both now and in the future, multiple medical experts said.

“If you start not vaccinating the kids from the primary series — like the measles, mumps, rubella, diphtheria, tetanus, pertussis, polio — then you risk those diseases coming back,” warned Dr. Anna Banerji, a pediatrician and infectious disease specialist in Toronto.

A vast majority of the Canadian public has been vaccinated against polio, and while immunization rates among children ebb and flow, the latest available federal data from 2017 shows roughly 90 per cent of toddlers had all three required polio shots. 

But that coverage isn’t uniform across the country. Polio vaccination rates were below 90 per cent in British Columbia and Manitoba, and close to just 80 per cent in Nunavut, while uptake in specific communities can vary and may have been disrupted by COVID-19 school closures.

Polio wards were lined not only with beds but with iron lungs, large metal ventilators that helped patients to breathe during the worst of the infection. Some survivors never regained lung function and spent the rest of their lives in the devices. (U.S. Food and Drug Administration)

“We do have our issues in Canada, with under-vaccinated communities for a variety of reasons, and a lot of this predates COVID-19,” said Bogoch, adding many public health teams across the country did offer immunization programs throughout the pandemic to get children caught up.

While pockets of the population could remain vulnerable to polio infection, Fatima Tokhmafshan, a researcher and geneticist at the Research Institute of the McGill University Health Centre, said most Canadians shouldn’t be overly concerned.

“If you see something circulating, it’s good to be on your guard, but not panicking,” she said. 

“So it’s important to keep an eye out. And reach out to your network, to your friends, your family — make sure everybody’s vaccinated.”

Quebec rejects plea to send army to northern region facing health worker shortage



MONTREAL — Quebec’s Health Department has rejected a request from officials in the northern region of Nunavik to have Armed Forces members brought in to help ease a shortage of health-care workers.

Kathleen Poulin, a spokeswoman for Nunavik Regional Board of Health, said Wednesday that labour shortages in the health sector are hitting Nunavik particularly hard due to the region’s “remoteness and its specific characteristics.”

“In some of the smaller villages that have only two to four nurses, the briefest absence can require a complete reorganization of activities in order to maintain services,” Poulin said in a statement.

“Considering the sizes of the communities, a handful of (additional) health-care workers can make a big difference in the level of services offered to the population.”

The health board, Poulin said, has been asking Quebec in recent weeks to supply medical workers. That included a request that Ottawa send Armed Forces members who can provide health care after some of Nunavik’s 14 Indigenous communities were forced over the summer to limit their services to emergencies only.

Health Minister Christian Dubé told reporters on Wednesday he would “soon” travel to the region to assess the situation, adding that Quebec has a “contingency plan” to handle the crisis.

“We have five or six paramedics already on their way, and doctors from other provinces that offered to help,” Dubé said.

The department, however, opted to seek the Canadian Red Cross’s help in Nunavik rather than the army, Dubé said, as the organization “helped a lot during the pandemic.” The department said the request for Armed Forces support was received Aug. 2.

“It’s a question of who’s the best and most appropriate group to complete our staff,” Dubé said. “The situation is already better than what it was.”

But Charlie Lapointe-Robert, a nurse who works in Inukjuak at the Inuulitsivik Health Centre, said Dubé’s statement is misleading. She said rather than being able to offer proper care to the community, health-care workers are forced to tell residents to “be careful.”

“We’re the ones who are supposed to take care of them,” Lapointe-Robert said in an interview on Wednesday, adding that her health centre still doesn’t know when to expect help from the government.

“We are accumulating delays, blood tests that need to be done, children’s vaccinations, followups, cancer prevention that isn’t done .… The situation is not better than it was. We are heading toward a greater crisis.”

The labour shortage in Nunavik’s health sector is not new — and neither are the requests for government action, Lapointe-Robert said.

The nurse, who’s currently on vacation in Montreal, said she doesn’t understand why it took so long to create a contingency plan as it is now a matter of days before the community could be left with no nurses on duty.

“We are on a tightrope, there is a risk of error and incredible tragedy,” she said, adding that normally up to six nurses are working in Inukjuak.

Poulin said a labour shortage affecting the entire province has left nursing agencies unable to meet the demand.

“Summer means vacation for many. It is necessary for the workers to take some time off, mostly after two years of COVID-19. Again, just a few people more or less make a big difference.”

The union representing nurses in the northern region, the Syndicat nordique des infirmières et infirmiers de la Baie d’Hudson, said it has been warning the government about the situation since last year.

“We are in a G7 country and I believe that the Inuit communities of Hudson Bay have a right to quality health care,” union president Cyril Gabreau said on social media. “Actions could have been taken yesterday to avoid tomorrow’s catastrophe.”
