If you’ve ever wanted to be a human guinea pig, now’s your chance. Before a COVID-19 vaccine can become a household name, it goes through months of testing by researchers around the world. Here in Halifax, scientists at the Canadian Centre for Vaccinology are working on three made-in-Canada vaccines—Medicago, VIDO and VBI—in hopes of finding the next Moderna, Pfizer and AstraZeneca. And they are looking for human guinea pigs who want to be test subjects. “Right now, we’re doing the first clinical trials of new COVID vaccines, featuring those that have been developed, that are based on Canadian technologies,” says Scott Halperin, an infectious disease specialist involved with the research. These vaccines are all created by Canadian companies that received federal funding: Medicago in Montreal, VIDO in Saskatchewan and VBI in Ottawa.
