In the end it is certainly your choice. Until I started working at a children's hospital I had neither ever had the flu vaccine or the flu and felt very much like you. As I had never had the flu I always figured that it was better for me to leave that dose for someone who really needed it, as it always seems to be in such short supply.

At this job I do feel very obligated to protect the patients, even if my chances of even getting the flu are pretty low.

I do however feel that if you choose not to get a vaccine (not just flu, but any vaccine) you should be aware of exactly what you are doing. Just because you are not part of a vulnerable population doesn't mean that you won't be part of the larger problem *if* you do get sick.

Really - read the article in Wired, its very well written.
