There are so many strains of the flu virus that very often they do fail to match the vaccination to the strain. This is because there are several strains going around the country at the same time. I have read this and it contradicts the CDC's claims to "accuracy" but I can;t point to an article - it's just knowledge stored in my under-sized over-stuffed little brain.

I never had a flu shot. I don;t get the flu shot because I worry that I'll be using a vaccine to do something that my immune system needs to identify and fight off. I don;t know if this is correct reasoning or not, but I've settled on it. Perhaps when I'm older I may need to re-evaluate this thought process...or maybe when I educate myself more on the benefits of the vaccine versus letting your body work it out on its own.
