Healthcare professionals at the Allegheny Health Network in Pittsburgh reported the case on Monday, noting that a 65-year-old man arrived at the hospital with a serious form of blood clotting known as thrombosis with thrombocytopenia (TTS) just 10 days after his second and final dose of the Moderna shot. Two days later, the unnamed patient, who also suffered from chronic hypertension and high cholesterol levels, died, with doctors concluding his symptoms were consistent with vaccine-induced clotting, also known as VITT.
“The distribution of thrombosis, especially the cerebral venous sinus thrombosis, was characteristic of VITT or TTS,” the doctors wrote in a journal article published at the Annals of Internal Medicine.
