It mutates. Besides washing your hands not much you can do.
The who 'flu shot' is for retards. They pick the strain they think (guess) is going to be the majority strain in the whole country. Last year was a complete miss as a example. This virus is dangerous because its brand new and doesn't show during the contagious period in the beginning.

CDC knows the effectiveness year to year can vary, but overall it’s statistically very significant in softening the blow of the flu annually.

Especially for children. Even 47% effectiveness is a relatively high percentage on a cost/benefit ratio. The cost of a flu shot is next to nothing (with most insurances having it cost-free), and it only requires a single shot. As a counter example, I had to get an anthrax vaccine when I was stationed overseas and it required 6 pretty painful shots, and the effectiveness % of the vaccine was fairly abysmal.
