I should add this also:
Common things to do to avoid the flu are avoid crowds, avoid sniffling/sneezing/coughing people especially. STAY WARM - the influenza viruses can be killed with heat (don't try to knock back your body's fever response too much - try to let it go as long as it's staying between 100 and 103 for a couple days. Don't keep your house too cold if you can help it, and wear multiple layers and stay warm when outdoors. Wash your hands for 15 seconds using rapid/high friction hand washing techniques with good plain soap (micelle formations, mechanical debridement) after each contact with public surfaces (public door knobs, phones, keyboards, money etc.). If the dreaded pandemic does come (and it will eventually), consider getting yourself fitted for the N95 respirators when you travel outdoors.

Ultimately the thing that will save you will be your own immune system - there are certain people who will be naturally "immune" to the pandemic virus and it is these people mostly who will survive without a scratch. This is pure genetic lottery and there's nothing you can do about it and no way to find out if you are one of the genetic lottery winners until you are actually exposed.
