Thorsen was a leading member of a Danish research group that wrote several key studies supporting CDC’s claims that the MMR vaccine and mercury-laden vaccines were safe for children. Thorsen’s 2003 Danish study reported a 20-fold increase in autism in Denmark after that country banned mercury based preservatives in its vaccines. His study concluded that mercury could therefore not be the culprit behind the autism epidemic.
His study has long been criticized as fraudulent since it failed to disclose that the increase was an artifact of new mandates requiring, for the first time, that autism cases be reported on the national registry. This new law and the opening of a clinic dedicated to autism treatment in Copenhagen accounted for the sudden rise in reported cases rather than, as Thorsen seemed to suggest, the removal of mercury from vaccines. Despite this obvious chicanery, CDC has long touted the study as the principal proof that mercury-laced vaccines are safe for infants and young children. Mainstream media, particularly the New York Times, has relied on this study as the basis for its public assurances that it is safe to inject young children with mercury — a potent neurotoxin — at concentrations hundreds of times over the U.S. safety limits.
