A discredited anti-vaccine advocate who has no medical background and who has been disciplined for practicing medicine without a license will reportedly lead a questionable federal study on vaccines and autism—despite a large volume of existing research that has found no link between the two and despite a thorough debunking of claims that vaccines cause autism. Late Tuesday, The Washington Post reported that David Geier has been hired as a "data analyst" by the Department of Health and Human Services, which is now headed by Robert F. Kennedy Jr., a prominent and fervent anti-vaccine advocate. Kennedy and Geier have both long touted the false claim that vaccines cause autism, despite the extensive evidence showing that they do not. In March, HHS directed the Centers for Disease Control and Prevention to reexamine the nonexistent link between vaccines and autism, using funds from taxpayers that could have been directed at other research. David Geier earned a Bachelor of Arts degree from the University of Maryland, Baltimore County, in 2002. Since then, he has largely worked with his father, Mark Geier, also an anti-vaccine advocate who falsely blames vaccines for autism. In 2011, Mark Geier was stripped of his medical license by the Maryland State Board of Physicians for misrepresenting his credentials, failing to meet state and federal regulations on safety oversight, and allegedly putting the safety and welfare of autistic children at risk. The board found that the elder Geier "misdiagnosed autistic children with precocious puberty and other genetic abnormalities and treated them with a potent hormonal therapy ("Lupron Therapy" or "Lupron Protocol"), and in some instances chelation therapy, both of which have substantial risks of both short-term and long-term adverse side effects. [Mark Geier's] treatment exposed the children to needless risk of harm." Lupron is a drug that suppresses sex hormones (a gonadotropin-releasing hormone [GnRH] agonist) and is used to treat prostate cancer, endometriosis, and precocious (early) puberty. It can also be used for chemical castration. In a linked case, the state physician's board also found that David Geier, who worked closely with his father, was practicing medicine without a license. He was issued a civil fine of $10,000.

“Numerous conceptual and scientific flaws”

The two Geiers have published a long list of questionable studies in obscure journals claiming to find harms of vaccines and links to autism. One focus of their work has been to claim that thimerosal, a mercury-containing preservative previously used in vaccines, causes autism. No credible evidence of harms from thimerosal has been found, according to the CDC. And regardless, the preservative was largely removed from vaccines in 1999. Many of their articles have drawn widespread criticism from scientific and medical experts, including the American Academy of Pediatrics. In 2003, the AAP blasted one of their articles that claimed to find a link between thimerosal and autism. The AAP said the paper "contains numerous conceptual and scientific flaws, omissions of fact, inaccuracies, and misstatements." When the Post reached David Geier for comment on his role in the HHS and how he was hired, Geier said, "I don’t have any comment to say. Talk to the secretary [Kennedy]. He’s the person that’s in charge." To experts, the conclusion of Geier's upcoming CDC study on vaccines and autism is a foregone one. "It seems the goal of this administration is to prove that vaccines cause autism, even though they don’t," Alison Singer, president of the Autism Science Foundation, a nonprofit organization that funds autism research, told the Post. "They are starting with the conclusion and looking to prove it. That’s not how science is done."
