The Abbott government has closed another loophole on children's vaccinations, ending a religious exemption that allowed Christian Scientists to get childcare benefits and not vaccinate their kids.

Last week, Social Services Minister Scott Morrison announced that parents would no longer be able to conscientiously object to vaccination and still claim childcare and family payments from the government.

But he kept exemptions on religious and medical grounds, noting there was only one religious organisation exempt. Online information prepared by Mr Morrison's department clearly stated the church was the Church of Christ, Scientist - more generally known as the Christian Scientists.

However, a spokeswoman for the Christian Scientists told Fairfax Media that the church was in fact "very neutral on the subject of vaccination".
