An extra 5,700 Australian kids have been vaccinated this year.

The Federal Government is celebrating the success of its ‘No Jab, No Play’ policy, which sees certain family payments withheld from parents who refuse to have their children vaccinated.

The policy prevents payments to those who conscientiously object to vaccination for philosophical or religious reasons as well.

It has been in place since January this year.

Since that time, the immunisation rate for one and five-year-olds has reached 93 per cent, up from around 90 per cent before the policy.

Social Services Minister Christian Porter says that threatening to withhold family welfare payments shows how serious proper vaccination is.

“We were facing a situation where the medical community were telling us that ‘herd immunity rates’... need to be 95 per cent, and we were just dropping steadily below that,” Mr Porter told the ABC.

“We would've liked to have gone about this some other way, but this was the most practical and effective way — and look, it's working.

“It means that all parents can be absolutely certain and secure now that when their kids are going into childcare, that the Government's enacted a policy that's lifted the immunisations up for things like whooping cough and polio, so that kids are protected in childcare.”

Immunisations have now been delivered to 5,738 children whose parents previously objected to them receiving adequate health care.

Over 148,000 children who were lagging behind with their vaccinations are now up to date.

“Vaccination rates had fallen to such a historically low level, that we were seeing the re-emergence of diseases that we had been free of for years,” Mr Porter said.

“Of course, that was a matter of major concern to the overwhelming majority of parents who aren't vaccination objectors and just want their kids to be safe.”
