I'm going to give this thread about ten more seconds before it gets shipped off to the vaccinations section!

My synopsis is, if you aren't sure, DON'T vaccinate. You can always vaccinate your child, at any time. Any doctor will be more than happy to shoot you up. But, you can never take away a vaccination. Once it's done, it's done, so be sure before you do it.
One useful book is Aviva Jill Romm's "Vaccinations". She covers all the vpds - signs and symptoms, side effects, history of each disease and history of each vaccine, and then offers a variety of treatment options. It's not super biased towards not vaccinating, but does lean a bit that way, especially for certain vaccines. However, it's all very rational and researched, and also very readable.
Have you talked to an ND about homeopathic vaccines? I'm not as up on those, but I know they exist, and they might be a middle ground if you're looking for one.
I'm also pretty sure (it's been awhile since I looked) that there's a resources section in the vaccinations area of MDC. I know they have the exemption forms for various states and provinces listed there, which shouldn't be an issue right off the bat, but it's nice to have it bookmarked for later.
We're not vaccinating. At all. We were a little torn about the tetanus vaccine, and have left space to change our minds on that one, for sure. Our daughter(s) will be given information and the opportunity to choose the rubella vaccine at puberty, if they don't wind up with natural immunity, same with mumps for our son(s).
Overall though, my general philosophy is that people get way to excited about this issue. It's a personal choice, and as long as you're making an INFORMED decision, you just do the best you can with what you know and go from there.
