I too want proof in 20 years. Look at the autism out break. When i was a child it was 100,000-1 now its 105-1. Furthermore therisol build-up is the culprit. They mandate shots for things like chiken pox...Most people have chicken pox, you don't die from it why vaccinate against it.
This type stuff makes me nuts.
I'm wondering myself about the link between vaccines and asthma. The thinking in the medical community for some years now is that having a too clean environment and not enough illnesses can be a contributing factor in allergies and asthma. They are both on the rise and so is the number of vaccines given kids.
