In 2008 vaccines contain many animal products such as eggs and bovine cells. If you read a vaccine information insert (I can't remember which vacine, will have to look it up!!) it will say that it is UNLIKELY that mad cow disease can be transmitted through vaccines!! Pretty scary stuff!!
Of course adults can get childhood illnesses but if they get them as children when they are supposed to have them, the effects are not nearly as bad.
Your statistics on polio are not that different to mine(LOL) If you look at the history of polio it was already declining before the vaccine was introduced.
There is no doubt that some vaccines work. The question is at what cost to our childrens health?
If you look at the insert for the Hep B vaccine given to babies, the so called "immunity" wears off after seven years or so. So why give it to babies? Aren't high risk people drug users and people getting tattoos and having unprotected sex?
It's all about the almighty dollar! As asked previously, what agenda do you think anti vaccination groups are pushing? What do they have to gain from parents not vaccinating?
