Yes, every year their are many flu virues that go around. So vaccinating yourself against one virus, the h1n1, and supressing your entire immune system in hopes you will be able to prevent that one virus (the vac is less then 50% effective) doesnt make sense. Have they ever tested the safetly of the h1n1 vaccine on Asthmatic kids? Last i check it was only tested on kids with no health issues and even many of them had bad reactions.
Focus on being healthy. Eat healthy good foods. Limit sugar. Get sunlight so you body has Vit D. Eat superfoods and herbs that contain all the nutrients you need. Even Echinacea can be beneficial, its been shown to be better then the drug Tamiflu.
