Fugitive Scientist Behind Vaccine and Autism Studies Arrested for Stealing $1 Million From CDC

Danish scientist Poul Thorsen — co-author of influential 2002 and 2003 studies often cited to dismiss a vaccine-autism link — was arrested in Germany and may be extradited to the U.S. on charges of embezzling nearly $1 million from the CDC. His arrest raises new questions about the integrity of the studies used to shape vaccine policy worldwide.

Danish scientist Poul Thorsen, who co-authored influential papers in 2002 and 2003, used to argue against the link between vaccines and autism, was arrested in Germany and may be extradited to the U.S. on charges of stealing nearly $1 million in research money, Breitbart News reported.

Thorsen was listed as a fugitive on the U.S. Office of the Inspector General’s most wanted list for over a decade.

He reportedly was arrested in June following an Interpol Red Notice, a request to international law enforcement to locate and provisionally arrest a wanted person. The U.S. Department of Justice (DOJ) is working with German authorities to extradite him to the U.S., an unnamed DOJ official told Breitbart.

Thorsen allegedly absconded with over $1 million from the Centers for Disease Control and Prevention (CDC) as part of a scheme to steal grant money awarded to governmental agencies in Denmark for autism research.

A federal grand jury indicted Thorsen in Atlanta in 2011 on 22 counts of wire fraud and money laundering. However, Denmark previously refused to extradite him, so he wasn’t prosecuted, Forbes reported.

‘Number one’ on the HHS most wanted list

Thorsen’s research, allegedly “debunking” the link between autism and the measles-mumps-rubella or MMR vaccine and other thimerosal-containing vaccines, was cited by the Institute of Medicine (IOM) as proof of no link.

His research was also used as evidence in the National Vaccine Injury Compensation Program’s (VICP) proceedings to deny the injury claims of more than 5,000 families.

Thorsen’s findings have been widely criticized by safe vaccine advocates as seriously flawed and potentially fraudulent.

“Thorsen has been number one on the Health and Human Services (HHS) most wanted list for the past 10 years,” HHS Secretary Robert F. Kennedy Jr., a long-time critic of Thorsen’s studies, told Breitbart following reports of Thorsen’s arrest.

HHS did not respond to The Defender’s request to confirm whether Thorsen had been detained.

Author James Grundvig told The Defender that Thorsen’s arrest has the potential to expose a long history of misconduct within the CDC.

Grundvig wrote “Master Manipulator: The Explosive True Story of Fraud, Embezzlement, and Government Betrayal at the CDC,” which details the story of Thorsen’s alleged role in a broader CDC manipulation of vaccine safety studies.

“It is not just Thorsen,” Grundvig said. “It won’t be just taking down one guy.” If Thorsen is compelled to testify, “he will be pointing fingers and naming names.”

Children’s Health Defense Chief Scientific Officer Brian Hooker said:

“I really want to emphasize that this crime is much bigger than Thorsen. His collaborators need to be brought to justice as well. They partied on the backs of many autistic children. Frankly, jail time is too good for Thorsen and the many other fraudsters at CDC, IOM and the VICP!”

Thorsen used grant money to buy home, motorcycle, cars

Beginning in the 1990s, Thorsen, who worked as a visiting scientist at the CDC when the agency was soliciting grant applications for research about infant disabilities, advocated for grants on behalf of Danish scientists and institutions.

Between 2000 and 2009, the CDC awarded over $11 million to two Danish government agencies to study the relationship between vaccines and autism, and other infant developmental issues, according to a 2011 press release by the U.S. Attorney’s Office for the Northern District of Georgia and Grundvig’s book.

In 2002, Thorsen relocated to Denmark to serve as principal investigator on the grant, overseeing the distribution of research money. The research was done by Aarhus University and Odense University Hospital in Denmark.

Between 2004 and 2008, Thorsen allegedly submitted more than a dozen fraudulent invoices on CDC letterhead to the medical facilities conducting the research for costs incurred for work related to the grant.

The facilities transferred hundreds of thousands of dollars in payments to fake CDC accounts at the CDC Federal Credit Union in Atlanta. However, the money actually was deposited into Thorsen’s personal accounts.

Thorsen allegedly used the money to purchase a home in Atlanta, a Harley Davidson motorcycle and cars, among other items. Overall, he withdrew more than $1 million, according to reports.

The indictment charged Thorsen with 13 counts of wire fraud and nine counts of money laundering, each carrying potentially long prison sentences and heavy fines. It also sought forfeiture of all property purchased with the fraudulently obtained funds.

Fabricated results seem ‘all but certain’ in research involving Thorsen

Mainstream media writers have mocked the long-term critiques of Thorsen’s work as “conspiracy theories,” and argued that, as a co-author, his contributions to the papers didn’t skew the results.

In a Substack post detailing Thorsen’s history and the studies he co-authored, scientist James Lyons-Weiler, Ph.D., said Thorsen’s influence on the research was concerning and the studies themselves were flawed.

He said:

“Although his scientific findings must be evaluated on their own merits, including data sources, design, and replicability, his case may be critical in revealing decision-making and could produce evidence of wrong-doing by Thorsen and others. Defrauding the US Government of research dollars is a crime. (This includes misuse and scientific fraud).

“Results fabrication in the Danish registry results seems all but certain given the clear evidence of those practices in other studies on the topic of vaccines and autism.”

The Danish government, since 1968, has maintained an extensive registry of birth and health records on all of its citizens. This provided a rich database for research on childhood disabilities, Grundvig said.

According to Lyons-Weiler, the Danish registry studies published by Thorsen and others were riddled with methodological flaws, including vulnerability to confounding variables over time, shifting diagnostic categories that distorted the data, misclassification and reporting biases and conflicts of interest.

Lyons-Weiler called for greater transparency in that research, including access to the original datasets, registries, study methods and peer review processes.

He said the studies should be replicated, the policies derived from them should be reexamined, and the public should be provided clarity on which studies Thorsen influenced.
