Vaccinations

[mom-in-alberta]

We have to be sooooo careful about sharing families information. There is such an onus on keeping private information (including medical info) private these days.
If you are looking to change contract stipulations, then I would do it by giving ALL parents the updated info. With or without an explanation of the "why" behind the change; that is up to you. I would steer clear of mentioning that you are going to be accepting a new family whose children are NOT vaccinated, because clearly everyone will know who that is when they start.
Just keep everything very general when it comes to information.
