Measles is really nasty.

Most people think about measles and they think of it as a mild disease that is... quickly over and quickly forgotten that this is not some benign childhood rash.

And there was a particularly striking study a few years ago

Or if you've gotten a vaccine, these are the cells that make you immune to whatever you're vaccinated against.

As if you had never seen it. It's as if it's the first time. It wipes out a lot of the old memories. You know, it depends. If Measles has completely wiped out that part of her repertoire, it's as if you've never seen it. If it got part of it but not all of it, it's somewhere in between. But that's one insidious feature of this.

This is basically... It's not just for complicated, serious cases. It's common. I can't say universal, but it's extremely common.

I thought, this is bad stuff, to be honest.
