Hehehe.... there have been a couple of discussions on here re: vaccinations and I have noticed that it tends to be a hot button for some!! :P
Personally, I have 3 kids that ARE vaxed and one on the way that I have not yet decided about. I have a number of kids in care right now, and I honestly don't care if they have had them or not. It has never come up in an interview, and if it did, I would tell them my kids' situation but not the d/c kids. If they were concerned, I may tell them either "yes, they all have the up to date" or "no, some of them do not". Or flat out that I don't know. I would not reveal WHO does not have the vaxes done. That's a privacy thing for me. Then it is their decision as to what they are comfortable with.
