This is, for sure, one of the more heated topics that parents face. I identify with your concerns, and am a mom to a 26-weeker who is now 2 1/2 years old and doing very well.
I've been reading about this issue (both sides) for about 3 years now, and my husband and I agree in holding off at this point on all vaccines for our son. He has had some lung challenges and a few rounds of surgeries for various things, and we can't imagine introducing all of the foreign substances that are a part of vaccinations into his system. (It's not just about mercury; there is formaldehyde and other things -- you have to read the inserts. Ever heard of a "murine antibody"? It comes from a rat. Yuck!)
But each parent has to make the decision themselves. I actually posted because I wanted to mention a correction to a prior post, that gave some misinformation about what is required in the State of Michigan, if you choose to waive vaccinations.
Someone posted that you need a "religious" exemption for this, but that is not the only option. The State of Michigan allows 3 exemptions: medical, religious, and philosophical. Some states do not allow a philosophical objection (which basically means you can reject vaccinations for ANY reason), but Michigan does -- thanks to Mary Tocco and her organization (believe it's Michigan Opposing Mandatory Vaccines).
I just wanted to share that info because, if you do decline, you should not be pressured or bullied by the school systems to provide doctor's info or religious info. By law, you are not required to.
Our son is receiving some in-home speech therapy from our school system, and they wanted to know why he didn't have a vaccine record and gave me some forms for his doctors to fill out. I informed them that, by law, I can object to the vaccines and, because they are public schools and we're taxpayers, they cannot deny us services. I'm polite, but informed -- and they get the point very quickly that I'm not going to be bullied. Now, if it's a private school or daycare, then the lines aren't as clear -- so you would need to pick & choose carefully if you go that route.
So far, things have gone well for us and I intend to stay informed so I can speak intelligently about the legitimate concerns linked to vaccines (yes, I'm aware there is a new study saying there are no links; do you know who funded the study? take a guess ...) as well as my rights.
Best wishes to you, whatever your decision. If you want more info personally, you may e-mail me at ____@____.com.
