No, we have never done flu shots and will not start now. I started reconsidering after hearing all the recent media reports, but now feel comfortable with our decision despite it being a bad flu season. We are a pretty healthy family, and none of us has ever gotten the flu (not even me, as a health care worker, being unvaccinated and being exposed to flu many, many times). I am fully aware that this could be 'the year' one (or all) of us gets sick, but I'll throw my lot in with mother nature and our bodies' amazing defense system, rather than with big pharma.
Because I work at a hospital, and refused the flu vaccine, I have to wear a mask when I walk through the hospital (I can take it off once I'm in the laboratory, where I work). It's ridiculous, but I do it without complaint. I've refused the vaccine every year, and I probably take the fewest sick days out of everyone else (I am the only one who refuses the vaccine). By all statistics, at least half of my vaccinated co-workers are just as 'vulnerable' as I am, being completely unvaccinated. Also, the efficacy of masks preventing flu is questionable- There is no good evidence showing that wearing one can prevent transmission...
Just my little rant there, a little off-topic 
Best defense in my opinion is to eat well, get plenty of sleep, wash your hands, and just be vigilant of your surroundings- keep kids home if there is a flu outbreak at school, etc.
