Is the fact that our 5 mo old son is behind on his immunizations going to get us in trouble with DHS/CPS?

My wife and I were surprised with a random visit by a Department of Human Services social worker tonight. The social worker said someone called in and complained about how well we take care of our five month old. He had no problems with anything after the interview; except that our son is behind on vaccinations due to our moving to a new state and having to change Medicaid to the new state. My question: is DHS likely to make an issue of this? All the social worker told us is that we're to get the immunizations up to date by the end of the week and then call him afterwards to let him know. We have no problems or ethical issues with getting baby immunized, just got a little behind on paperwork during the move.
