That graph is quite convincing. To a point. The vital information is missing. What happened after the Thiomersal (mercury) was removed? If incidence of autism went down to, say, 1980 levels, then it looks like the increase was down to the mercury. If it was the mercury, they wouldn't admit it. And if it wasn't the mercury, why did they remove it? In any case, the mercury is gone. What are the anti vaccine people saying is causing the trouble now?
