A.,
Having had extensive personal experience with the vaccine controversy issue, I felt I had to weigh in. Firstly, allow me to point out that vaccines are not the only option when it comes to immunizing. There are also homeopathic immunizations, which are perfectly acceptable alternatives, and are composed of natural extracts rather than chemicals, diseases, heavy metals, and other toxins. The choice to avoid vaccines does not mean you choose not to protect your child...it means you decide to find other means of protection.
Also, you stated that daycare requires a religious exemption if you don't vaccinate...this is also untrue. A medical waiver is just as legal and acceptable as a religious one. Furthermore, the religious waiver is very flexible...it is not limited to any particular faith, and it does not require that the doctrine of your faith prohibit vaccinations. You just have to state that you believe exposing your child to the risks of vaccines is against the tenets of whatever higher power you place your faith in.
As for my personal experiences, there is a strong history of adverse reactions to vaccines in my family. I am deathly allergic to all vaccines (getting any vaccine at all causes anaphylactic shock, a life-threatening reaction, so I can't even have a flu shot when the flu season rolls around...oddly enough, I never get the flu). My brother went blind at the age of four months due to a routine DPT shot. He is now 28 years old, and my mother has still never forgiven herself for believing the vaccine hype and blinding her only son. My sister's two children both suffered horribly from the hepatitis shot that is given in the hospital at birth...both girls developed such horrible eczema that they had to spend the first several years of their lives completely naked...clothing of any sort would cause their skin to break open and bleed...and even without clothing they were still constantly raw and in pain just from ordinary contact with anything.
I guess my point is that there is a lot more that can go wrong with vaccines than just autism (although that is what you hear about the most, currently, it has not always been so). Fatalities may be uncommon, as may certain other adverse effects...but the fact that it's uncommon is no consolation when it happens to your own little one. There are plenty of options out there. Homeopathic immunizations are most easily substituted for vaccinations, since there is no waiver required as long as the child is immunized. So many people think that you have to be vaccinated to be immunized, they don't realize the waiver is only required in cases where the child is not immunized, which doesn't mean the same thing as not being vaccinated.
Due to our family medical history, we have a medical waiver rather than a religious one. My daughter's father had her illegally vaccinated despite the medical history and waiver...she is now 12 years old and suffers from almost constant gastrointestinal pain and is barely able to eat most of the time. None of the doctors or specialists can identify why this is happening to her. Before her father did this to her, she had never been ill, not even so much as an ear infection. However, since he did that, there is rarely a day that goes by when she is not ill in some way or other. She is also developmentally delayed, which was not the case before the vaccinations (which occurred when she was 4 years old). I am currently remarried, and expecting a newborn baby girl any minute now, and my husband agrees it is not worth taking the chance to have this baby vaccinated. I believe I can count on him to continue to stand by that stance, but I realize there is always the risk that he, too, will cave in to pressure and propoganda as my previous husband did.
The most important thing is not to believe anything that anyone tells you. Not me, or any of the other anti-vaccination crusaders, or any of the pro-vaccination crusaders...do your own research, study every angle and view, and come to your own conclusions. Only you can determine what's right for your child.
