I’m going to take a break from All Things Trump this morning to talk about two important misperceptions in American life:

The Flu. If you’re like most American adults, you haven’t gotten a flu vaccine this year.

Maybe you think you don’t need one, because you’re not elderly or a child. Or maybe you think it’s too late. But none of that is correct. You should get a flu vaccine every year — for your own sake and for the sake of public health — and it’s not too late to get one this year.

Flu season remains near its peak through February, and the flu remains a risk well after that, as Aaron Carroll, an Indiana University medical professor, told me yesterday. Carroll has written two recent Times pieces making the case for taking the flu seriously. It’s the country’s eighth-leading cause of death.
