It is possible for the creators of cures of diseases to patent their ideas. These diseases don't belong specifically to them, or anybody for that matter. Some people just happen to contract them. Continued research on patented cures is not allowed, unless the researcher pays the patent owner for access to all the previous research and development of the vaccine or process.
Each of these vials has a patent number for a real US patent. I then placed them in an acrylic box with a lock, signifying that only people with the correct authorization or "key" can access the cures for these diseases.
