Australian Prime Minister Scott Morrison has back-tracked after suggesting vaccinations against the coronavirus could become mandatory.

澳大利亚总理斯科特·莫里森曾建议强制接种新冠肺炎疫苗，但现在他收回了这一建议。

Announcing a deal that could provide free doses to Australia's entire population, Mr Morrison had said there should only be medical exemptions.

But after concerns raised by health experts, he clarified: "There are no compulsory vaccines in Australia."

Meanwhile, visitors to Australia may also be required to have immunisation.

Health Minister Greg Hunt said he "wouldn't rule out" making it mandatory for anyone travelling to Australia - including Australians returning to the country - if that was the advice from medical experts.

"It would seem passing strange if we had a massive vaccination programme in Australia but we were then to allow people in who could bring it in," he told A Current Affair.
