I work in a cancer centre here at Sunnybrook hospital in Toronto. So I kinda had to get the vaccine. I feel like most people that don't get it, don't get it because they think they are immune, or won't get too sick from the flu etc. But they are missing overlying point, which is to avoid you spreading the flu to someone else who might be much more at risk of getting severely sick etc.

Clearly my getting the vaccine is 5% to protect me from getting very sick, but 95% protecting me from making any of the patients here get sick.
