I get a flu shot every year, hoping, thereby, to stave off the flu. Haven't we been told ad nauseam that the shot itself can't give you even a mild case of the flu? Well, I've been under the weather all evening and all day after getting my flu shot yesterday afternoon. My body temperature is 99.9º. (It's normally 97.5º.) I canceled today's bike ride and have been taking short naps. I should be fine for tomorrow's lectures. Just warning you.
Addendum: Now they tell me.
