Good points, Harry. It's kinda' like putting the cart before the horse...

A number of the drugs we use right now (and vaccines used for other purposes), were stumbled upon, based on a hypothesis. (Admittingly, many of the drugs are not doing a LOT to help many of us, but they are working for some.)

I wouldn't want to be a trial like this, but I am certainly glad there are people out there who are willing to. I wouldn't mind being in the Tovaxin trial though; I have high hopes for that treatment.
