Which COVID-19 Vaccines are worse for CVST Blood Clots.
The risk of developing a serious brain clot – known as a cerebral venous sinus thrombosis (CVST) – is 8 to 10 times higher in people with Covid than those who get a vaccine.
The European Medicines Agency says a particular type of CVST occurs in around five in a million people after the first dose of the Oxford-AstraZeneca vaccine.
In those who had an mRNA vaccine – such as the Pfizer or Moderna jab – they estimate CVSTs occurred in around four in a million people.
