that's exactly the point: the vulnerable should get vaccinated because the flu can kill you anywhere, not specifically because you might get the flu at a game.

that's exactly the point: the vulnerable should get vaccinated because the flu can kill you anywhere, not specifically because you might get the flu at a game. that latter sort of reasoning is irrational because the added risk is inconsequential relative to the overall risk. you shouldn't try to time the shot to right before going to games, because that's irrational. get it before the flu season, and then this tiny added risk matters even less.
