Random Analytica: AstraZeneca COVID-19 vaccine and cases of Thrombosis with thrombocytopenia syndrome (TTS)

AstraZeneca is in the news this week after the Therapeutic Goods Administration (TGA) reported the death of a 52-woman from New South Wales from thrombosis with thrombocytopenia syndrome (TTS). This is the second fatality linked to the AstraZeneca vaccination roll-out following the death of a 48-year old female in April. As tragic as the deaths are there have been almost 3.3-million doses of AstraZeneca administered (to the 6th June 2021) with just 48-cases of TTS being reported to date. For context it looks like you could expect an adverse reaction resulting in death in 1 in every 1.65-million doses. According to Ian Mackay from Virology Down Under “It’s a real number. A real risk. But a very rare one”.
