So, the vaccine/autism link is utterly fallacious--not just mistaken, but a deliberate fraud. Several medical studies had disproved it already, but now we have an investigative reporter who's traced down the mechanics of it--and and the motive. Money, of course. A conspiracy between the good doctor and a lawyer to extort money from vaccine manufacturers.
Not that this will stop people from believing. It's like the birthers. You could produce Obama's birth certificate till the cows come home, and those who disbelieve it would continue to do so. It's important to their world view.
We all live within our own myths.
