Clot risk ’10 times higher’ with COVID-19 than vaccines

Researchers have provided a rule of thumb guide to the absolute incidence of rare clotting events

The risk of serious thrombotic events posed by SARS-CoV-2 infection is up to 10 times higher than the risk associated with COVID-19 vaccines, a study suggests.

UK researchers who have crunched the numbers say their analysis, yet to be published in a peer-reviewed journal, could help inform public debate about the risks and benefits of vaccination.
