The laws on human medical trials often mandate this kind of testing. New vaccines, for example, must be tested on animals (primates) before they are approved by Public Health Agency of Canada. Whether or not that is correct or useful or justified is definitely up for debate, but we would not be able to pursue or utilize any of these advancements or medicines without first changing the regulations. That’s the place to start, for sure.
