Prime Minister Scott Morrison has announced new advice will be provided to Australians under the age of 50 regarding the administration of the AstraZeneca vaccine following "unforeseen" side effects.
The Australian Technical Advisory Group on Immunisation (ATAGI) has met to consider medical evidence regarding side effects mostly associated with younger people from the vaccine.
"As always, we will encourage Australians to seek out the advice of their own doctor in relation to these issues," the prime minister said.
Chief Medical Officer Professor Paul Kelly reiterated the potential for blood clots - as evidenced in cases around the world - is a very rare event.
"At the moment, it seems to be around four to six per million doses of vaccine. It's only been found in the first dose of the AstraZeneca vaccine, usually within four to 10 days after that vaccine," he said.
"But it is serious, and it can cause up to a 25 per cent death rate when it occurs."
