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.
"I think it really is important that people realise the value of immunisations and protecting their children and that will help to protect the community."
Immunisation rates for Aboriginal children have risen by almost 10 per cent in Adelaide and 7.7 per cent across the state.
Almost 85,000 babies and small children across Australia were not immunised in 2014-15.
More than 1200 post codes did not meet the national child vaccination target of 95 per cent.
