Assuming they know they’re vulnerable they presumably wouldn’t go to these parties. However that’s quite an assumption, particularly among young people.

Because shutting down the economy will kill people, too. It will also decrease quality of life for everyone, and disrupt families, communities, cities and countries.

I don't even know what the best course of action is, but there are trade-offs that a lot of people here seem to be ignoring.

I'm pretty sure OP meant, exclude them from going to the party.

Not exclude the statistic
