> failing to prove a link between autism and vaccines is not proof of the contrary. What about the fact that rates of autism have not increased since the introduction of MMR - is that proof of the contrary? In Britain, the rates are 1:100 in adults which is the same as in children young enough to receive the MMR (since the 1990s). It doesn't strictly prove the contrary, but it also doesn't prove that the World Wide Web does not cause autism. I would also suggest that strong opinions expressed by Gates are often HN worthy.
