Flu shots are worth it. There is a small chance you'll get a little sick. Not sure how small but pretty small, and nothing bad if it does happen. On the other hand you won't get the flu and anyone who would have caught the flu from you won't catch it since you never got it in the first place. Basically flu shots = lives saved, less flu shots = more deaths. I'd feel really bad if someone got the flu because I didn't get a shot, especially if someone ended up dying. That would add another tally to my already staggering list of kills by neglect.
