On April 13th, the CDC/FDA recommended a pause in administration after 6 cases of cerebral venous sinus thrombosis (CVST) with thrombocytopenia were identified through the vaccine adverse event reporting system in women aged 18-48. To date, 15 cases of thrombosis with thrombocytopenia syndrome (TTS) have been reported following vaccination with J&J, with three reported fatalities2. Here we report one of those fatalities in a 35-year-old woman who developed CVST with thrombocytopenia following vaccination with the J&J vaccine.
