I am against having other people's views forced on others. But I concede that in the case of immunistaions, there are probably parents who have no objection to immunisation, but forget that they are due, have difficulty getting to a GP or health clinic and probably in a few instances just couldn't be bothered with it all. So it is probably fair enough in a way that there are reminders and follow ups, and that you need to get a form signed if you choose not to. It at least means that you have to give it some thought and make a decision, not just ignore it. But you should not be cricised for making an informed decision, whatever you decide.
