Health authorities have urged parents not to become complacent about vaccinating their children as a report reveals varying immunisation rates across Adelaide suburbs.
Children in Adelaide's northeast have the second-highest vaccination rates in Australia, the National Health Performance Authority says.
More than 98 per cent of one-year-olds in Fairview Park, Surrey Downs and Yatala Vale were immunised in 2014-15.
But Glenelg, in Adelaide's west, had some of the nation's lowest vaccination rates of just over 82 per cent.
"There's always going to be some variation, but it is disappointing that some of the well-to-do suburbs are not doing as well as some other suburbs," SA Health chief medical officer Paddy Phillips told ABC radio on Thursday.
