EMA Reiterates No Cause Yet Established for AstraZeneca Vaccine and Blood Clots

April 5, 2021

The European Medicines Agency (EMA) confirmed that it has not found any causal link between blood clots and inoculation with the AstraZeneca (AZ) COVID-19 vaccine.

The agency has not yet been able to identify specific risk factors, such as age, gender or previous medical history which may be causing the clotting. So far, 62 cases of cerebral blood clots have been reported to the EMA, including several resulting in death.

By the EMA’s estimates, 9.2 million people in the European Economic Area have received the AstraZenec vaccine, but there is “no evidence that would support restricting the use of this vaccine in any population.”

The agency is investigating additional cases from Germany and elsewhere ahead of follow-up meetings slated for April 6-9.
