Richard, much truth in what you say but my point is that in a terminal case with little time left there is not much to be lost but much to be gained. On lab animals this vaccine seemed to work and even cure late stage cancers. If years are wasted on research many will die. If it will work on humans the quick proof is in it's application. This is what happened with insulin years ago. Banting did not even want to patent his discovery but donate it to mankind. However, I believe that the University Of Toronto were not willing to relinquish their interest. The big drug companies look to a cancer cure as a bonanza, and sometimes laws written with good intent may allow them to place a foot in the door of a house that they did not build.
