> At least one covid vaccine trails has already failed because the vaccine wasn't safe (in the case I know of because you show up HIV+ even months latter which makes those tests worthless - the vaccine might have worked against Covid for all I know). That may be a good enough to nix development for common cold vaccine, but how can one argue that it’s serious enough problem to cancel vaccine for disease that kills thousands of people every single day? This is another example of how “safety” and “ethics” regulations have little to do, and in fact are counterproductive to achieve safety and ethics in real world.
