Mark Robin Geier (1948–) and David A. Geier[note 1] are a ~~couple of vultures~~[note 2] father-son team of American anti-vaccine advocates who specialize in quack cures for autism.

The Geiers are perhaps best known for their truly bizarre theories regarding androgens and mercury. In 2004, Geier advanced a hypothesis that testosterone increases the potency of mercury.[2] This led the Geiers to invent and patent a therapy regimen of chelation and Lupron,[3] an anti-androgen. Lupron is normally only given to children who show signs of precocious puberty,[4] so what the Geiers suggested was way off-label.[note 3] Their solution? Declare that all the children in their studies had precocious puberty.[5]

This regimen is, to put it mildly, controversial among actual scientists in relevant fields.[6] Fortunately, as of 2009 they no longer have access to Lupron.[7]

As of early May 2011, the Geiers' controversial "therapy" has been found to be a concern by the Maryland State Board of Physicians.[8] Fortunately, they have also decided that Mark Geier's therapies pose such a threat to children with autism that he was stripped of his medical license.[9] David Geier, his son, is not and has never been a doctor of any kind, and in the same case was charged with practising medicine without a license.[10]

In 2025, David Geier was appointed by the Trump administration to oversee a government study on vaccines and autism.[11]

## Notes[edit]

1. ↑ Not to be confused with the orthopedic surgeon David Geir, who is not antivax[1]
2. ↑ "Geier" is German for "vulture" and the behavior of these two practically forces this association upon any German-speaker and the unfortunate birds who are dragged into this.
3. ↑ Not to mention incredibly unethical.
