Studies positing a link had already been used in lawsuits by hundreds of parents who believed acetaminophen – the drug’s medical name – had caused their children to develop autism or ADHD. Now, Kennedy said, the FDA had even more robust data to support that link. Kenvue has since lobbied the FDA to prevent new warnings about the risk of using Tylenol during pregnancy from being added to its product.

Solving the explosion in chronic diseases among children is one of the central targets of the Make America Healthy Again crusade. Just look at autism, the incidence of which has increased from perhaps 1 in 500 children in the early 1990s to 1 in 31 today – staggering growth that obviously can’t be explained by genetic factors alone.

The response to such observations from the mainstream media, leftist politicians and medical professionals has inevitably been to pour scorn. Virtually every claim that Kennedy makes, from the benefits of whole milk to the toxicity of the herbicide glyphosate, is treated as a dangerous “conspiracy theory,” the product either of discredited “quack” science or of the Health Secretary’s famous brain parasite.

Now, a new study suggests Tylenol could be just the beginning of this story. Fifteen common drugs taken during........
