OMG, I wouldn't do that for even $10,000. I have asthma, and any respiratory ailment like the cold or flu has me coughing for at least 4 weeks. It's awful. I don't sleep, I cough to the point of choking, I can't take a deep breath for weeks, etc. If I had to go through it, I think I'd set my price at $25,000 minimum. For that amount, I suppose I'd do it.
(And in case you're curious, I absolutely get a flu shot every year; I get one as soon as they're available!)
