USask unites: VIDO-InterVac team tackles coronavirus: Researchers developing prototype vaccines at USask

Since the first cases of COVID-19 were announced in the province, members of the USask community have come together to support one another in these uncertain times.

Extraordinary circumstances have brought out extraordinary responses from members of our USask community. From frontline health-care workers to researchers looking for a solution to this global health threat, there are so many stories about people are working to make our home communities safer and healthy. Here are a few of the inspiring stories of our students, staff, faculty and alumni.

As the world deals with the new pandemic, coronavirus has become the No.1 priority for researchers at the Vaccine and Infectious Disease Organization-International Vaccine Centre (VIDO-InterVac) at the University of Saskatchewan (USask).

With the World Health Organization confirming that the new strain of coronavirus, SARS-CoV-2, continues to spread rapidly (more than 114,000 people infected in 110 countries and more than 4,000 deaths as of March 10), VIDO-InterVac researchers have successfully grown the virus in a cell culture and are now testing a new vaccine in animals as part of the global effort to combat the coronavirus threat.

“The virus continues to spread, with more cases and further geographic reach than what was initially anticipated,” said Dr. Volker Gerdts (DVM), director and CEO of VIDO-InterVac, which received approval in early January from the Public Health Agency of Canada to work with this new strain of coronavirus. “I think the world is preparing for a scenario where this coronavirus will continue to appear over the next few years. I don’t think this is going to go away like SARS-1 did.

“We are working with the World Health Organization, and I attended a meeting in Geneva to lay out the blueprint for this disease (COVID-19) and the research that needs to be done.”

Scientists at universities and research facilities across the country and around the world are working on the coronavirus outbreak, with VIDO-InterVac collaborating with a number of labs at home and abroad, including the National Microbiology Laboratory in Winnipeg. Gerdts said VIDO-InterVac—one of only a handful of labs in the world that currently has been able to isolate the virus—is taking a leading role in the global fight against coronavirus.

“We are very well-positioned for this,” said Gerdts. “We are one of the few facilities approved to work with it. There are a lot of labs and a lot of people with ideas, but there are only a few labs like ours that can actually do the work. VIDO-InterVac is one of the largest Level 3 high-containment facilities in the world. There are four pathogen levels, and SARS-CoV-2 requires Level 3 containment.”

While testing is still in the early stages, Gerdts said they hope to have an indication by early April whether the vaccine generated at VIDO-InterVac is successful in protecting against the infection. Gerdts said it would likely take another six months of testing, development and manufacturing before the vaccine would be ready to go into clinical testing.

“We have worked on other coronaviruses, including MERS and SARS, and coronavirus infections in cattle and pigs,” said Gerdts. “We have developed two coronavirus vaccines for animals, so based on our expertise and knowledge, we believe that our approach may work with this outbreak.”

With additional staff and resources already re-allocated for the coronavirus research, Gerdts is looking for more funding to prepare for the next phase of clinical human trials. This includes current efforts to build a pilot-scale manufacturing facility within VIDO-InterVac’s Level 3 containment facility.

“Current manufacturing capacity for vaccine development is extremely limited in Canada,” he said. “We want to build a manufacturing facility that allows us to manufacture vaccine candidates and take them into clinical testing for humans and for animals. We recently received funding to start Phase 1 of the VIDO-InterVac manufacturing facility. We need another $10 million to fully establish the manufacturing facility to industry standards. Once established and fully operational, the manufacturing facility could also play a role in Canada’s emergency preparedness for this and other emerging infectious diseases.”

In addition to combating the coronavirus outbreak spreading through the human population, VIDO-InterVac is also working hard on a vaccine to fight the growing threat to the world’s swine population, with serious implications for global food security.

“African swine fever is spreading and VIDO-InterVac is the only non-government Canadian facility that has received permission to work with the virus, and that disease—in the global picture—is equally important. It is not affecting humans, but there are estimates that every third pig on this planet is going to die from this disease and that would have a major impact on protein supply, so it is huge.”
