Staying away from the global cooling stuff for now, I'll comment on this.<p><pre><code>     McCarthy has a long history of dismissing epidemiology,

That's not really true.  The problem is that there have been no studies made regarding vaccine and autism. McCarthy believes they are linked and asks to be shown a study proving they are not.  (A study that takes populations of vaccinated children and unvaccinated children and compares their autism rates)  No studies are available, and years later, that remains true.<p>Given that this is pretty easy to find out, I think this author has their own little axe to grind.
