Not everybody thinks it will be effective. Associate Professor Julie Leask, from the University of Sydney: "The Abbott government's tough new stance on immunisation will only increase vaccination rates by an "absolute maximum of one per cent," a Sydney immunisation expert says. University of Sydney associate professor Julie Leask said the federal government's move to prevent parents who don't vaccinate their children from accessing childcare payments and family tax benefits would not have a "meaningful" impact on overall immunisation rates. Professor Leask said about 2 per cent of parents were currently registered as conscientious objectors to immunisation and of those, half were "hard core" while the other half would still give their children some vaccines. She said that the hard core group would not be moved by the new policy, with only those who were partial objectors potentially open to changing their view. Professor Leask said that there was a much larger group of parents - of about 4 or 5 per cent - who did not vaccinate their children or keep them updated for practical or logistical reasons."
Christian Scientists will be the only exempt group.
