What is the source of the false and misleading vaccine claims repeated by Trump and RFK Jr.?

Trump's false and misleading vaccine claims, such as the assertion that vaccines cause autism or that aluminum adjuvants are toxic, trace their origin to discredited sources like Andrew Wakefield's retracted 1998 Lancet study and anti-vaccine advocacy groups. These claims are also amplified by misinterpretations of VAERS (Vaccine Adverse Event Reporting System) data, which do not establish causation. RFK Jr.'s claims, including similar assertions about vaccine safety and autism, are sourced from his own published books and statements, as well as from anti-vaccine organizations like Children's Health Defense, which he leads. Both figures have been fact-checked and shown to propagate misinformation without scientific basis.
