A study from Oxford University found that the number of people who receive blood clots after being vaccinated with a coronavirus vaccine are almost the same for those who receive Pfizer PFE,
and Modern MRNA,
vaccines as they are for AstraZeneca AZN,
vaccine that was produced with the help of the university. According to the study, 4 out of 1 million people experience cerebral venous thrombosis after receiving the Pfizer or Moderna vaccine, compared to 5 out of every 1 million people with the AstraZeneca vaccine. The risk of contracting TVC is much higher for those receiving COVID-19 – 39 in a million patients than for those receiving the vaccine. The use of AstraZeneca vaccine has been stopped or limited in many countries due to blood clots.
