Australian regulators have uncovered six more cases of rare blood clots linked to the AstraZeneca vaccine.
The Therapeutic Goods Administration said four cases were confirmed and the other two were deemed probable.
The new cases include a 57-year-old woman from Victoria, a 53-year-old South Australian man and an 18-year-old woman in Queensland.
The teenager received the vaccine before health advice was changed to say Australians under-50 should get the Pfizer option.
An earlier case of a 79-year-old Victorian man has also been confirmed, while authorities are seeking more information on two probable cases among two women aged 71 and 87.
The latest cases take the Australian total to 24 out of the 2.1 million doses of AstraZeneca administered in Australia.
"Overall, 21 of these cases are considered confirmed and three are considered probable," the TGA said on Thursday.
"Three of the four cases reported as probable in last week's report have since been confirmed as TTS (rare blood clots). The other case remains under investigation."
