  • This vaccine can cause TTS, which may be life-threatening.
  • TTS may involve thrombosis at unusual locations for a thrombus (e.g., central artery/vein, cerebral vein, extremity artery, visceral artery/vein) or in an extremity vein or pulmonary artery.
  • Among reported cases of TTS following administration of this vaccine, symptoms began approximately 1 to 2 weeks after vaccination.
  • The clinical course of TTS following administration of this vaccine shares features with autoimmune heparin-induced thrombocytopenia (HIT). In patients with suspected TTS, the use of heparin may be harmful, and alternative treatments may be needed.
  • Vaccine recipients should be instructed to seek immediate medical attention for chest pain, leg pain, neurological symptoms (e.g., severe/persistent headaches or blurred vision), persistent abdominal pain, petechiae beyond the site of vaccination, or shortness of breath.
  • This vaccine should not be administered to individuals with a history of thrombosis with thrombocytopenia following this vaccine or any other adenovirus-vectored COVID-19 vaccine.

  • Patients with a severe allergic reaction (e.g., anaphylaxis) to any of the ingredients
  • Those with a history of TTS following administration of this or any other adenovirus-vectored COVID-19 vaccine
