New research conducted by a team of scientists from Flinders University and international experts has uncovered crucial information about vaccine-induced thrombosis and similar disorders. They found that the dangerous PF4 antibodies responsible for these conditions have identical molecular structures with those found in cases following natural adenovirus infections. This groundbreaking discovery has significant implications for future vaccine development and disease management.
During the peak of the COVID-19 pandemic in 2021, a new condition known as VITT was linked to adenovirus vector-based vaccines, like the Oxford-AstraZeneca vaccine. VITT is caused by a blood autoantibody targeted at a protein called platelet factor 4 (PF4). Further research in 2023 revealed that a similar disorder with the same PF4 antibody was found in cases after natural adenovirus infections.
Collaborating with international researchers, the team at Flinders University discovered that the PF4 antibodies in both conditions share identical molecular fingerprints. This research will not only help improve vaccine development but also shed light on genetic risk factors. The findings, published in the New England Journal of Medicine, provide valuable insights for future medical advancements.
