HHS, under the direction of RFK Jr., has hired known conspiracy theorist and quack David Geier to run a planned study which will investigate the thoroughly disproven idea of a link between childhood vaccinations and autism. David Geier and his father Mark have a scandalous past of subjecting autistic children to unproven medical treatments for their own financial gain. They have published multiple fake studies claiming a link between vaccines and autism. Hiring David Geier is a clear indication that the Trump administration plans to rig the upcoming study and claim that it proves vaccines cause autism. This will set public health back decades at a time when vaccine hesitancy and infectious disease are both spreading at alarming rates. This plan will harm autistic people and the health of all Americans. We urge members of Congress to demand accountability from HHS for this dangerous and destructive decision.
