Overwhelming science—over 450 studies—by then attested to thimerosal’s devastating toxicity.31 Because testosterone amplifies the neurotoxicity of the mercury molecule, boys disproportionately suffered reduced IQ and a range of developmental disorders—ADD, ADHD, speech delay, tics, Tourette’s syndrome, narcolepsy, ASD, and autism following exposure to ethylmercury in thimerosal. Numerous studies link thimerosal to miscarriage and Sudden Infant Death. There is simply no study ever published that demonstrates thimerosal’s safety.
