A second Australian has died after suffering blood clots directly linked to the AstraZeneca vaccine.
The Therapeutic Goods Administration (TGA), which is overseeing the rollout of the vaccine, confirmed the woman's death on Thursday.
She was a 52-year-old woman from New South Wales.
The TGA confirmed the woman was one of four reports of blood clots and low blood platelets confirmed to be Thrombosis with thrombocytopenia syndrome (TTS) in the past week.
"This case presented as a severe form of this syndrome, with a blood clot in the brain, known as a cerebral venous sinus thrombosis," the TGA is quoted as saying by 7 News.
So far there have been 35 people confirmed to have contracted TTS after receiving the AstraZeneca vaccine.
Thirteen people have been marked as probable cases. Fifteen people are in hospital, one in intensive care and two have died.
Currently, the AstraZeneca vaccine is only recommended to Australians over the age of 50, due to the slight risk of blood clots.
