Leading doctors disagree on move to allow over-60s to opt for Pfizer vaccine in some states

Some of Australia's leading doctors have mixed views over multiple states making the Pfizer coronavirus vaccine available for over-60s.

Queensland, South Australia and WA have now all invited the older age group to have that jab, despite official advice being to give that age group AstraZeneca and save Pfizer for younger people.

But some seniors have said they didn't want AstraZeneca because of the very low chance of blood clots, which is slightly higher in younger people.

Infectious diseases expert Dr Paul Griffin said while AstraZeneca remains safe and effective, if the change means more people get vaccinated then he welcomed the move.

"It would be nice to have some unity in these decisions but of course it does come down to a state-based decision," he told A Current Affair.

Former Deputy Chief Medical Officer Dr Nick Coatsworth said with the disease spreading among younger adults in NSW and Victoria, they're the ones who need to get Pfizer.

He said didn't agree older people, who are most likely to die from the virus, should be offered it too in those places.

"When there's enough AstraZeneca and mRNA vaccines - Pfizer or Moderna - for the entire community, by all means, have a choice," he said.

"But at the moment, the choice is AstraZeneca or not to be vaccinated, and I think the choice is clear."
