Scientists consider they might have discovered the ‘trigger’ behind the extraordinarily uncommon blood clot issues stemming from the Oxford/AstraZeneca vaccine.

According to a global crew of researchers from Cardiff and the US, the response will be traced to the best way the adenovirus utilized by the vaccine to shuttle the coronavirus’ genetic materials into cells binds with a selected protein within the blood.

This protein is called platelet issue 4 (PF4).

Researchers consider this sparks a sequence response within the immune system which might culminate within the improvement of blood clots – a situation often called vaccine-induced immune thrombotic thrombocytopenia (VITT).

Professor Alan Parker, from Cardiff University’s School of Medicine, defined: ‘VITT solely occurs in extraordinarily uncommon instances as a result of a sequence of complicated occasions must happen to set off this ultra-rare facet impact.

‘Our knowledge confirms PF4 can bind to adenoviruses, an essential step in unravelling the mechanism underlying VITT. Establishing a mechanism might assist to stop and deal with this dysfunction.

‘We hope our findings can be used to better understand the rare side effects of these new vaccines – and potentially to design new and improved vaccines to turn the tide on this global pandemic,’ he added.

Scientists from AstraZeneca additionally took half within the analysis, which was printed within the journal Science Advances.

A spokeswoman for the corporate instructed the BBC: ‘Although the research is not definitive, it offers interesting insights and AstraZeneca is exploring ways to leverage these findings as part of our efforts to remove this extremely rare side effect.’
