I'm in MI and don't recall anything being asked about it. I do recall freaking out about everything like this though.
I'm not sure if you're adopting or interested in foster care. We're doing foster-to-adopt.
I know that housepets in my state must be up to date on shots and paperwork must be shown to prove it. I freaked out that they would make us catch the stray barn cats that call our farmstead home and force us to get them shots. 7 cats x $60 each = out of the question with our budget. Our licensing worker simply asked, "Do the cats come inside?" When the answer was no, she went on.
We also freaked about our century-old farmhouse not having a septic and well system up to today's codes. In fact our well did not pass inspection because of a minute issue (water did test safe to drink, which is obviously important to us as well), so we are on a conditional license that means every 2 years they have to reinspect our well. They have to renew our license every 2 years anyway! And our worker said our well inspection can keep failing every time and they just have to note it and reinspect until we can afford to fix it — if ever!
The bottom line is that the workers who do home studies are human beings who want safe and loving homes for the children. Maybe some workers are more by-the-book than others. Our experience was that there is a desperate need for foster parents and our home was determined to be a good place to raise children. I'm sure you'll find the same.
If you can do a waiver, great. If you need to explain it, maybe just stating your vax choices with confidence will help quell any fears. If you were to say, "Oh, we never got around to getting those shots," well that's maybe something for a worker to get concerned about. But if you say something with confidence maybe you'll be fine. "After a great deal of research we have made the conscious decision not to vaccinate our children or to selectively vaccinate them (and maybe add that you breastfeed and don't have your children in large group settings which also reduce risk if that is the case)." I've even used doctors who are not my doctor in some cases when explaining things to people. Today a doctor asked why I give our foster baby Vitamin C and seemed to think I was nuts. I finally said, "I'm giving it at the advice of a physician at the dosage he recommended," and she stopped questioning me. Well the doctor is Dr. Sears and I read it on his web site, but she didn't need to know that.
Good luck!
