Well, I don't think I trust that guy if the title is an indication of his intelligence. AIDS isn't a virus, HIV is but AIDS is not.

Anyway, with that in mind.. I've read a few articles by folks in the "industry" who talk about what ends up in those vaccines... Even if the above guy (didn't read the story yet, just to be clear here) isn't all that bright, there appears to be substance to some of the claims.

Also, it has been mentioned on numerous occasions (via news articles) that the facilities that manufacture vaccines can be pretty filthy.
