In June of 2000, the Center for Disease Control, the World Wealth Organization, the FDA, "leading" scientists and representatives of the pharmaceutical industry got together for a secret meeting.
Their focus was the growing public and scientific awareness that mercury used as a preservative in vaccines for children had unleashed an epidemic of autism.
The participants came to three conclusions:
1. They acknowledged the autism/mercury connection was true (or at least highly plausible)
2. They conspired to create a statistical smokescreen to obscure the science
3. They agreed not to disclose anything that took place at the meeting
It is, in short, an outright lie, repeated by Fletcher (who does her level best to come across as the reasonable face of anti-vax frothing). But she (and others) know that they can make and repeat this kind of mental conspiracy theory bollocks until the cows come home, and there's nothing that anyone can do about it.
She's an evil witch and wants locking up.
