Your child most likely will be able to attend school without being immunized. You will just have to get waivers signed by doctors and give your reasonings by doing so. A lot of families choose religious reasons, etc. You really need to research though not giving your child the important vaccines that they need to prevent diseases that could potentially kill them. I too, have read the book and researched information on her. It sways both ways... some people say that certain vaccines have an effect, but I don't believe there is any research/hard evidence to proove that vaccines are a CAUSE for autism.
Best of luck!
Depends on the state you live in. Most have philosophical exemptions. You need to sign waivers and agree to quarentine your kid if there is an outbreak(Doesnt make sense to me but ok). Don't let the school scare you or bully you. Most old yello shot cards have the waiver on back or you can find a waiver on line for your state. I homeschool my kids so don't worry about that.
