AstraZeneca vaccine: Clues to ‘trigger’ of rare blood clots studied by scientists

In a new study published Wednesday in the Science Advances journal, researchers, including some at Cardiff University and Arizona State University, say they have found that a protein in the blood, “platelet factor 4,” can bind to a key element of the AstraZeneca vaccine, potentially triggering a reaction with antibodies attacking the protein. However, questions remain over whether the binding is a direct cause of the blood clots.
