Listen, it's a common reasoning fallacy. There are so many shots that are given to kids. There is nothing can happen in a child that isn't a week or two after a shot or a week or two before the shot. And it sure seems like there's a relationship. It sure seems like it. And if there is, we need to find out. But we're just wasting and spinning our wheels, not getting to the bottom of autism, by constantly having to put down a theory that kind of came and it kind of went.
