I never had a problem and I don't think you can exclude on basis of immunisation status.
:yeahthat:

It is discriminatory to exclude on the basis of not having been vaxed, but it doesn't mean it doesn't happen behind closed doors.

I think it is very sad that many people get their child vaxed without thinking about it at all. I told someone in my MG that we were delaying vaxing DS, and she said "Oh, are you allowed to do that?" Certainly the questions from my GP, MCHN, in-laws, parents in my MG, friends, etc, all say "so, when is DS getting his vax?" and "has he had his needles yet?" Yet it never occurred to any of them that vaxing is not compulsory - because the government allows people to think that it is. I know Rhea Dempsey refers to this as "Nudge Economics" - where you have to "opt-out" of treatment/intervention rather than opt-in. And in order to "opt-out" you have to have give your reasons why, be assertive, well-informed, etc. To receive treatment/intervention is expected and is the norm - yet you don't have to be educated/informed or assertive to receive it.
