What you get in return is somebody (the government) took the risk of a blind faith payment to have a university develop a vaccine. That's what you paid for, not for production, not for distribution, not for anything else. You didn't pay taxes for a free vaccine, because you don't pay remotely enough taxes for that to be viable at all. Unless every country on earth takes their fair share of blind-faith financing a single company.
