The Therapeutic Goods Administration is investigating three new reported instances of blood clots in Australia in people who received the AstraZeneca vaccine.
Last week the TGA confirmed the fatal blood clotting suffered by a 48-year-old Australian woman was likely linked to the AstraZeneca COVID-19 vaccine.
She was the third Australian to have developed clots after the vaccine.
The three new cases are a 35-year-old woman from New South Wales, a 49-year-old Queensland man and an 80-year-old Victorian man, who is the first case over 50 years of age.
The AstraZeneca vaccine has been recommended for people over 50, while Pfizer is preferred for Australians under 50 because the clotting cases, until now, have all been in that age bracket.
