Australia’s Deputy Chief Medical Officer Professor Michael Kidd has stated that a blood clotting problem which led to a vaccine recipient being hospitalised was likely linked to the Astra-Zeneca Covid-19 Vaccine. Note the USA mostly sources vaccines from Johnson and Johnson and Pfizer.
Melbourne blood-clotting case ‘likely’ linked to AstraZeneca vaccine, Deputy CMO says
Australia’s Deputy Chief Medical Officer says it is “likely” there is a link between the AstraZeneca vaccine and a Melbourne man being hospitalised with blood clots.
“Given how consist of the clinical features are in this case, with some similar cases which have been seen overseas, it is likely that this case, which is reported, is related to the vaccine,” he said.

It is obviously unsettling to read about cases of adverse reactions, but in my opinion the balance of risk still favours vaccination. The original Covid death rate was around
2% 0.5-1%. Although improved therapeutics have brought the Covid death rate way down, the health risk associated with catching Covid appears to be significantly worse than the risk of a severe adverse reaction to the vaccine.
Correction (EW): h/t Andy – The 2% was based on my incorrect memory of a WHO estimate, but my memory was wrong – the WHO estimated 0.5-1% after taking into consideration an estimate of asymptomatic or mild cases which were not accounted for in original estimates. I’m not sure how good the WHO estimate is, other estimates range from 0.1% to 25%, according to the WHO, so feel free to throw a dart.
