A 'no jab, no play' bill will be introduced to South Australian parliament on Wednesday, requiring children attending day care centres to be immunised.
The bill attracts a $30,000 fine for any centre that enrols a child not immunised or covered by exceptions, says Health Minister Peter Malinauskas.
"By encouraging the vaccination of children, we want to improve South Australia's overall immunisation coverage and reduce the number of serious illness," Mr Malinauskas said.
