Prime Minister Scott Morrison says Health Minister Greg Hunt will be back at work when Parliament sits next week, after a brief hospital stint.
Mr Hunt was admitted to hospital yesterday with a suspected infection.
His office said he would be kept overnight for observation and was being given antibiotics and fluid.
"He'll be fine by next week, he'll be back up on his feet," Mr Morrison said.
"Minister Hunt and I have worked hand in glove over this last year and until he returns I will be personally addressing the ministerial responsibilities on health and aged care."
The Prime Minister said he had total confidence in the AstraZeneca vaccine. Mr Hunt's office said his condition "is not considered to be related to the vaccine".
He is expected to make a full recovery.
Fellow Cabinet minister Dan Tehan said he spoke to the Health Minister yesterday and that Mr Hunt was confident he would be out of hospital "sooner rather than later".
"I don't think there is a fitter or more active member than Greg," Mr Tehan said.
"So if there's anyone who can bounce back it will be Greg, but when I spoke to him yesterday he was going well."
Mr Hunt is the third senior Cabinet minister now on sick leave, with Attorney-General Christian Porter and Defence Minister Linda Reynolds also currently on leave.
Foreign Affairs Minister Marise Payne is acting Defence Minister and Employment Minister Michaelia Cash is filling in for Mr Porter.
The next Parliament fortnight kicks off next week.
