Since Med Journal Watch has comments turned off, I'm going to comment here.
He's right on nearly all his points, but he missed a BIG one.
The discussion of Autism related to the alleged prenatal exposure to Thimerosal from Rhogam requires a visit to the Rhogam web site
Since at least 2001, THERE IS NO THIMEROSAL IN RHOGAM. Scroll down. You'll find it.
Once again, statistical nonsense which totally ignores reality. Thimerosal must cause Autism, according to the anti-vaxers, so there must be thimerosal in Rhogam.
Even when there isn't.
Update: See Christian's comment. The only thing he missed was the date when the Rhogam (or similar product) was given. The study subjects were prior to the exclusion of Thimerosal.
I haven't been able to access the full text of the study yet. I'll keep trying, but I did a little investigation of the researchers. Christian, of Med Journal Watch, is quite right to be suspicious. The researchers definitely have a dog in this fight. Dr. Mark Geier is a paid professional witness in anti-vaccine trials. He has had his testimony stricken on at least one occasion because he did not have the necessary credentials to be an expert witness in that case.
Additionally, Dr. Mark Geier has been cited for attempting to breach confidentiality and had a different study suspended for that reason.
For some very interesting information on the Geiers, see this post on the Neurodiversity Weblog.
As an Rh negative mother of a young adult with ADHD (too old to have gotten prenatal thimerosal), I'd be interested in research that truly shows a higher incidence of any type of developmental issue in children of Rh negative women. The study population was only 53 and it truly was not a prospective study in the way I understand prospective studies. Further research would be interesting, but I'd want it done by someone who doesn't have anything to gain other than knowledge.
