Mccullough Foundation report
Determinants of Autism Spectrum Disorder
This report presents a comprehensive, evidence-based analysis of the determinants of Autism Spectrum Disorder (ASD), synthesizing epidemiologic, clinical, mechanistic, and population-level research across genetic, environmental, immune, and iatrogenic domains. Prepared by the McCullough Foundation, the findings identify routine childhood vaccination—particularly early, combined, and cumulative exposure during critical neurodevelopmental periods—as the most significant modifiable risk factor associated with ASD, alongside interacting genetic and environmental susceptibilities. The full report is available below as a downloadable PDF for those seeking a detailed examination of the data, methods, and conclusions that inform these findings.
