Thrombosis with Thrombocytopenia SyndromeThe Janssen COVID-19 Vaccine can cause thrombosis with thrombocytopenia syndrome (TTS) which may be life-threatening.TTS may involve thrombosis at unusual locations for a thrombus (ie, cerebral vein, visceral artery or vein, extremity artery, central artery or vein) or in an extremity vein or pulmonary artery.Among reported cases of TTS following administration of the Janssen COVID-19 Vaccine, symptoms began approximately one to two weeks after vaccination.Instruct Janssen COVID-19 Vaccine recipients to seek immediate medical attention for shortness of breath, chest pain, leg swelling, persistent abdominal pain, neurological symptoms (including severe or persistent headaches or blurred vision), or petechiae beyond the site of vaccination.The clinical course of TTS following administration of the Janssen COVID-19 Vaccine shares features with autoimmune heparin-induced thrombocytopenia. In individuals with suspected TTS, the use of heparin may be harmful and alternative treatments may be needed.Do not administer the Janssen COVID-19 Vaccine to individuals with a history of thrombosis with thrombocytopenia following the Janssen COVID-19 Vaccine or any other adenovirus-vectored COVID-19 vaccine .
