Here's a brief blurb from my immunology textbook:
"Although many substances and preparations are known to be adjuvants, the only adjuvants approved for use in human vaccines are alum - a form of aluminum hydroxide - and an emulsion of squalene, oil, and water called MF59."
According to this text, which is so new as to have a copyright of 2005 (I'm not kidding on this), squalene is not an "illegal" adjuvant.
For anyone who's wondering, an adjuvant is a substance that is added to a vaccine in order to enhance the immune response produced by the vaccine.
