H1N1 Swine Flu Prevention

My preschooler's school just sent a note home about the H1N1 (swine) flu. To prevent it, it says:

• Wash hands with soap and water frequently.
• Cover coughs and sneezes.
• Keep hands away from face.
• Practice social distancing (3-4 feet from others). Good luck with this one and kids. They all congregate in groups.
• Stay home if you are sick (at least 24 hours after fever is gone).
• Get seasonal flu shot. I'm not sure that is the answer. The vaccine has to be for the exact strain and with viruses mutating constantly, what are the chances that you are vaccinated for the exact strain? I'd like to know that. I'd also question giving my own child a vaccine that hasn't been tested long enough. Given all the health problems and deaths from the Gardasil vaccine, I do not trust Big Pharma or the government right now where it concerns vaccinations.
• Wear a mask to prevent spreading to others when ill. They've always done this in Japan. It's something you don't see much of here in the states.
• Hand sanitizer should be kept out of reach of all children and used with caution on children who place their fingers/hands in their mouth frequently. Not sure if this is due to the alcohol content or what. I know it used to be a problem.

That's what I have on prevention. For symptoms, click here. Will post more about what to do if you get it later.
