You’re selling a book that piggybacks off the popularity of the anti-vaccination movement, a movement that wouldn’t exist except for one very dishonest charlatan. Further, you imply that maybe there is something we don’t know about vaccines, the way we didn’t know that lead was toxic (although, I suspect, there were people that did know). The difference is that under scrutiny, lead was shown to be toxic. Under scrutiny, vaccines have not been. In fact, there’s a fundamental difference, because the scrutiny of vaccines begins from the outset of their existence. Lead, by comparison, was a ubiquitous part of our life before anyone scrutinized it.
