On the uselessness of chelation therapy for autism, update
Of note, Dr. Laidler also makes an interesting observation about the VAERS reporting system so beloved by mercury/autism advocates like the Geiers in "proving" a link between mercury and autism:
The chief problem with the VAERS data is that reports can be entered by anyone and are not routinely verified. To demonstrate this, a few years ago I entered a report that an influenza vaccine had turned me into The Hulk. The report was accepted and entered into the database.
Because the reported adverse event was so…unusual, a representative of VAERS contacted me. After a discussion of the VAERS database and its limitations, they asked for my permission to delete the record, which I granted. If I had not agreed, the record would be there still, showing that any claim can become part of the database, no matter how outrageous or improbable.
Since at least 1998 (and possibly earlier), a number of autism advocacy groups have, with all the best intentions, encouraged people to report their autistic children—or autistic children of relatives and friends—to VAERS as injuries from thimerosal-containing vaccines. This has irrevocably tainted the VAERS database with duplicate and spurious reports.
