Seriously. Seriously seriously if you can get the flu vaccine do it. It's not something you should wait on, not something to do next week. It's really important. Most colleges have vaccinations, I know the Walgreens near my house is doing them, the health department. They are emphasizing the old and the young but please please do it.

Don't put it off. Don't say 'you'll do it next week'- if you can conceivably do it, you really really should.
