Guidelines lack 'sensitivity' to detect early vaccine-related clotting

Dr Michelle Lavin, lead author of a scientific paper, said the risk of developing a blood clot from the AstraZeneca vaccine is still far lower than the risk of clots from Covid-19, but added it was “imperative” that clinicians are vigilant.

Current guidelines "lack the sensitivity" to detect early cases of rare clotting events related to the AstraZeneca vaccine, new research has found.

The work, led by researchers from the Royal College of Surgeons in Ireland (RCSI) and the National Coagulation Centre at St James’s Hospital, highlights the need for increased vigilance and early testing for patients.
