The Australian Technical Advisory Group on Immunisation (ATAGI) and the Thrombosis and Haemostasis society of Australia and New Zealand (THANZ) has prepared a joint statement on Thrombosis with Thrombocytopenia Syndrome (TTS) and the use of COVID-19 Vaccine AstraZeneca.

Key points

  • TTS, also known as vaccine induced thrombotic thrombocytopenia (VITT), is a rare newly identified condition with a different mechanism to other causes of thrombosis. Among case reports, there are no known markers for increased risk for TTS/VITT.
  • The risk of TTS is not likely to be increased in people with the following conditions, and people in these groups can receive COVID-19 Vaccine AstraZeneca:
    • History of blood clots in typical sites
    • Increased clotting tendency that is not immune mediated
    • Family history of blood clots
    • History of ischaemic heart disease or stroke
    • Current or past thrombocytopenia (low platelet count)
    • Those receiving anticoagulation therapy
    • The list of conditions for which Comirnaty (Pfizer) is the preferred vaccine has been expanded to also include:
  • Past history of idiopathic splanchnic (mesenteric, portal, splenic) vein thrombosis
  • Antiphospholipid syndrome with thrombosis 
  • TTS can be treated effectively. Guidance on the identification and management of TTS is available from the Thrombosis and Haemostasis Society of Australia and New Zealand.
