Pauline Hanson must apologise and retract her "crazy" comments on vaccinations, a former federal health department head says.
Stephen Duckett said he was "disgusted" when the senator questioned their effectiveness and encouraged parents to do their own research.
"This is a situation where you've got a popular politician with a significant following who's actually giving crazy, crazy medical advice," he told ABC radio on Monday.
"She has to apologise and retract that statement."
Senator Hanson also said parents should be allowed to have their children tested before booking vaccinations.
"Some of these parents are saying vaccinations have an effect on some children," she told ABC television on Sunday.
But Mr Duckett, who is now director of health at the Grattan Institute policy think tank, rejected this.
"Vaccines are safe," he said.
"I cannot stress how angry it makes one feel that she is putting lives at risk ... without any evidence whatsoever."
