We are not getting the shot because we don't believe it is necessary. We vaccinate for the necessary things and avoid over-vaccinating for things like the flu. A healthy immune system AND a healthy mental environment will keep your child from being sick.
Germs are EVERYWHERE. So why do some people get sick and others don't? The answer is an unhealthy OR overtaxed immune system. And having a lot of stress can cause your immune system to become overtaxed and the result is you get sick.
My stepdaughter is homeschooled so we have no worry of her picking it up at school. She does lots of activities with kids (such as gymnastics) so we make her wash her hands and take her vitamins. We also avoid sugar since it taxes the immune system as well. She rarely gets sick.
If she does get sick we use Miracle Mineral Supplement and she's well within a day or two. It works on viruses as well as bacterial infections.
As far as I know, the H1N1 Vaccine is not going to do anything horrible to your kids. It may or it may not prevent them from getting the flu. Everyone's body is different, and all I can say is there is no one "fix-all" solution that works for everyone.
If you're unsure about the long term effects of the vaccine, I'd just make sure your kids eat healthy, take their vitamins (including a large dose of vitamin C...try Emergen-C for kids) and have a healthy mental environment. Happy kids are healthy kids :)
Also, I've never had a flu shot because I am allergic to eggs and there is egg in the flu shot. I never get the flus that are going around, and I teach lots of kids three days a week! So it's just your own personal decision, don't let anyone make you feel bad for getting the shot or not getting it.
