Here are some folks to look at:
Dr. Eliav Barr. He's from Israel and worked on the Gardasil vaccine (clinical trials, I believe) for Merck, before story about him came out. As a gay man I wondered if he really understood the attitudes of parents who aren't wanting their children to live a promiscuous life. An HPV vaccine that causes disability, sterility and premature ovarian failure isn't beneficial even if it did prevent cervical cancer (does NOT seem to).

This Israel and US educated professor has turned her work towards vaccine advocacy. She is, imo, firm to the point of being rabid about her insistence that all children be vaccinated in lock step with CDC demands.

If you think there isn't a murderous agenda behind vaccines, think again.
