He has no formal medical training.

But he loves reading scientific papers.

And so what happened in August is that a Harvard professor put out a paper.

It was basically a meta-analysis of a bunch of other studies that showed a possible connection between

between Tylenol use during pregnancy and neurodevelopmental illness, including autism.

It was like a large epidemiological study.

So it's not showing causation.

It's showing, look, we looked at this large number of people.

We know these people took Tylenol.

We're seeing slightly higher rates among those people.

That could be a cause.

We don't know.

It's a correlation.

It could be a cause.

Kenny got very excited when the paper was published.

And he told me he spent that weekend reading 70 papers.

And he called other researchers who'd been working on this topic, people who'd been looking at the possible biologic connections here.

He called in the CEO of Kenview.

which is the company that makes Tylenol, and had him bring in his researchers, and came out of it with what he described to me, and I think it was a sort of nuanced view of what's going on here.

Fevers during pregnancy are dangerous for kids and mothers.
