Okay, but... logically,
if she's asthmatic, then she's high risk ON TOP of being high risk by virtue of being on a college campus, yes?
So if she's going to follow advice re: FluMist, then she sure ought to follow it re: asthma. (I know, I know-- nothing you haven't already pointed out to her... just... would her doc tell you if s/he thought the risk was higher re: FluMist or nothing at all?)
