Many of the vaccinations do not prevent the child from getting the illness just reduces the severity. For that reason some programs restrict unvaccinated children during an outbreak because it is believed they are more likely to catch the illness, be sicker and more likely to pass it on to the others who will then catch it even though it will me less severe but they will still be out of the program. Whether that logic makes sense or not - well the jury is still out. Some unvaccinated children are the most healthy ones out there but that doesn't mean they won't catch a virus as it passes through.

My kids are all older so most of the vaccinations available now were not available to them or my other daycare kids at the time and there was no increase in any of the diseases they vaccinate against now so I tend to be on the skeptical side as to whether this is a good thing to do or not. I totally leave it up to the parents to make a decision for their own child.

If you are going to accept the new family do you then have to let the other families in your care know about the change in the contract since they signed on fully knowing that all children would be vaccinated. Some may have very definite opinions too. Just something to think about.

I tend to leave some controversal things like this out of my contract so I can decide on a case by case basis. If I have a family come and they are adament one way or the other it can be a issue in the sense of will that family try to influence all future dealings with families.
