The Therapeutic Goods Administration believes that all of their illnesses are related to the dosage of the AstraZeneca vaccine.
You are a 74-year-old man and a 51-year-old woman in Victoria, a 66-year-old man in Queensland, a 70-year-old man in Tasmania and a 64-year-old woman from Western Australia.
They have all been hospitalized and the man in Queensland is currently being treated in the intensive care unit at Townsville Hospital.
Australia has recorded 11 cases of blood clots in recipients of AstraZeneca vaccines since launch, from approximately 1.4 million doses.
Four out of five people who developed blood clots from their vaccines in the week before the last clot, were discharged from hospital.
“The adverse event is still very rare and has a similar frequency as other countries that use AstraZenec vaccines,” said TGA chief John Skerritt on Thursday.
