EU Hits AstraZeneca Vaccine with Another Blood Condition for Side Effect List

The AstraZeneca COVID-19 vaccine takes another hit to its safety profile as the European Medicines Agency adds a new side effect to the label of its shot.

The EMA identified a rare blood condition, capillary leak syndrome, as a potential side effect of AstraZeneca’s Vaxzevria. The condition causes plasma leaks from blood vessels into neighboring body cavities and muscles. Blood pressure experiences a sharp drop as a result, and, left untreated, the disorder can lead to organ failure and death.
