Institute of Chronic Illnesses

The Institute of Chronic Illnesses is a non-profit research organization founded by Mark and David Geier, primarily known for its controversial work regarding the etiology and treatment of autism spectrum disorder. The institute promoted the Geier protocol, which hypothesized that mercury from vaccines interacted with testosterone to cause autism, leading to the off-label use of leuprolide (Lupron) and chelation therapy. These treatments were widely condemned by the scientific community for lacking empirical support and posing significant health risks to children. The organization's activities eventually led to the revocation of Mark Geier's medical license in multiple jurisdictions and the cessation of its clinical operations. Despite its controversial history, the institute remains a significant case study in the intersection of fringe medical theories and patient advocacy.
