evidence: Autism spectrum disorder is a complex neurodevelopmental disorder commonly manifesting in difficulties with social interaction and communication, among other symptoms. Epidemiological studies of hundreds of thousands of children have found no association between childhood vaccination and autism. Variants of the MTHFR gene are common and claims that MTHFR mutations lead to an inability to “detox” from vaccines are false. Reliable scientific evidence about glyphosate’s association with autism is currently lacking, although more research in this area is needed to better understand the potential impact of glyphosate exposure.
