In 2020, the lab is working with 300 ferrets developing a COVID-19 coronavirus vaccine candidate and testing other vaccine candidates and therapeutics. (VIDO-InterVac at the University of Saskatchewan via AP)The global race for a COVID-19 vaccine boils down to some critical questions: How much must the shots rev up someones immune system to really work? Shes awaiting results from mice, ferrets and monkeys that are being exposed to the coronavirus after receiving Inovios vaccine. Three recently reported studies in monkeys tested different COVID-19 vaccine approaches, including shots made by Oxford University and Chinas Sinovac. Ferrets the preferred animal for flu vaccine development may help tell if potential COVID-19 vaccines might stop the viral spread.
