The Australian Therapeutic Goods Administration is investigating three new cases of a rare blood clot syndrome “likely” linked to the AstraZeneca vaccine. The cases are a 35-year-old woman, a 49-year-old man and an 80-year-old man. It is the first time the syndrome has been reported in a person over 50 in Australia. The TGA said in a statement all cases were likely linked to the AstraZeneca vaccine. The TGA said one patient developed symptoms “unusually late” – 26 days after the vaccination.
