Health authorities are reviewing the deaths of two NSW men that occurred after they received the AstraZeneca vaccine.
A clear link between their deaths and the vaccine is yet to be established.
https://www.facebook.com/healthgovau/videos/495412415106227Tamworth man Darren "Misso" Missen, 55, reportedly died about eight days after receiving the vaccine.
His friend Mark said he was "fit and healthy" before his death last week.
"Darren had the corona jab end of last week was a little bit off colour at work early this week and died from a blood clot in the heart wednesday afternoon," he posted on Facebook last week.
A 71-year-old Sydney man also died days after receiving the AstraZeneca vaccine.
The vaccine has been linked to a rare but severe blood clotting condition called thrombosis (blood clots) with thrombocytopenia (very low platelets).
The Therapeutic Goods Administration has confirmed it has been notified about both cases.
"The reporting of an adverse event to TGA post vaccination does not mean the event was caused by the vaccination," it said in a statement.
"All reports to the TGA of death following vaccination are reviewed to assess the likelihood that the vaccine contributed to the event or medical condition that lead to a fatal outcome."
The TGA has so far confirmed six cases of the blood clotting condition after vaccination, including one linked to the death of 48-year-old Genene Norris from the NSW Central Coast.
But the drug regulator says the overall number of reports received for blood clots following vaccination has been no higher than the expected background rate for the more common type of blood clots in Australia.
"These can occur in around 50 Australians every day separate to vaccination and are not related to the rare TTS clotting disorder," the TGA said
