New research conducted by Flinders University and global specialists is deepening our knowledge of vaccine-induced immune thrombocytopenia and thrombosis (VITT).
During the peak of the COVID-19 pandemic in 2021, VITT was recognized as a new condition linked to adenovirus vector-based vaccines, particularly the Oxford-AstraZeneca vaccine.
VITT was found to be caused by an unusually dangerous blood autoantibody directed against a protein termed platelet factor 4 (or PF4).
“Indeed, the pathways of lethal antibody production in these disorders must be virtually identical and have similar genetic risk factors.
