"A vaccine made by the Chinese company CanSino Biologics was the first COVID-19 vaccine to enter phase II human trials. It was developed using adapted HEK-293 cells that the company licensed from Canada's NRC, where the cells were developed. (NRC-developed HEK-293 cells have already been used to develop an approved Ebola vaccine.) Last month, NRC announced a collaboration with CanSino Biologics under which it is preparing to run late-stage clinical trials of the vaccine in Canada, and scale up facilities to produce the vaccine in quantity."
