Anyway, isn't it slightly problematic to accept the benefits of modern medicine while insulting those who have participated in the studies which made it possible, by calling them a name (guinea pig)?
I work in a U.S. government office which gets loads of mail and is, I think, at moderate risk for receipt of a terrorist letter. If it were offered, I would gladly accept the bovine vaccine (never tried on humans except for rare errors, lasts just a year, becomes effective a lot quicker than human vaccine) on an experimental basis, knowing, without reading any silly release, that the personal benefit is iffy. Beyond knowing that I hadn't passively accepted my fate, I would have the additional psychic benefit of feeling myself an active participant in the war against terror. A little more reluctantly, I'd also accept the human vaccine. There is no risk-free medicine.
