Random Analytica: AstraZeneca COVID-19 vaccine and cases of Thrombosis with thrombocytopenia syndrome (TTS) to 13 June 2021

The Therapeutic Goods Administration (TGA) has updated its latest safety report with no new deaths being reported. Via the TGA. COVID-19 vaccine weekly safety report – 17-06-2021. Summary:

  • The most frequently reported suspected side effects associated with Comirnaty (Pfizer) and AstraZeneca COVID-19 vaccines continue to be events that were seen in the clinical trials, and are commonly experienced with vaccines generally.
  • Twelve additional cases of blood clots with low blood platelets have been assessed as thrombosis with thrombocytopenia syndrome (TTS) likely to be linked to the AstraZeneca vaccine. The increase in the number of cases correlates with an increase in the number of doses of AstraZeneca vaccine administered during the reporting period.
  • This brings the total number of confirmed and probable TTS cases in Australia to 60. Seven of the 12 new cases occurred in individuals in aged between 50 and 59 years. When assessed using the United Kingdom (UK) case definition, three cases were confirmed and nine were deemed probable TTS.

No data was available in this report on AstraZeneca vaccines administered (in the previous week 3.3-million doses were confirmed). At the same time the Australian Technical Advisory Group on Immunisation (ATAGI) recommended the age to receive a dose be increased from 50 to 60. To date there have been two TTS deaths linked to the AstraZeneca vaccine.

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”.

Random Analytica: From China with Love

I have been blogging for 10-years now. My best year was back in 2014 as I followed the H7N9 outbreak which originated in China. That year I garnered almost 33,000 views of which just 20 came from mainland China. I then took a break from blogging between 2015 – 2018. In late 2019 I started to blog about some of my experiences in the Australian Army. Since then the hits from China have increased from <1% to 16.7% this year while my Hong Kong viewers have disappeared. It is all the more interesting because I only dwell on Twitter (banned in China) and WordPress via social media. I’ve reached out to some experts in the field including Stephen McDonell (via the BBC) who is reporting in Hong Kong tonight from the vigil on the 32nd anniversary of the Tiananmen Square Massacre.
