Our findings provide reassuring preliminary data that BNT162b2 vaccination does not result in endothelial activation or a hypercoagulable state. While the definition and mechanism of (vaccine-induced thrombotic thrombocytopenia) VITT is more clearly defined and linked to the presence of PF4 antibodies, the cause of rare non-VITT thrombosis remains elusive. Additional studies will be required to identify the population at risk of vaccine associated thrombosis and how to monitor for this rare but serious complication.
