- Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a rare prothrombotic disorder with a unique clonality-restricted immunological profile. The study by Petito and Bury et al. provides insight into the role of HLA polymorphisms and an inherent predisposition to VITT. Commentary on: Petito et al.
