A few days ago, the European Medicines Agency confirmed the link between AstraZeneca’s COVID-19 vaccine and the incidence of thrombosis. Now it’s time for another test. The EMA is checking whether there is a link between vaccination with this preparation and a rare blood vessel disease – capillary leak syndrome.
- On April 7, the European Medicines Agency acknowledged that thrombosis could be a very rare side effect after vaccination with AstraZeneka
- EMA continues to hold its position that the benefits of this vaccine in preventing COVID-19 outweigh the risks of side effects
- On Friday, EMA said it was examining the link between AstraZeneca and another possible side effect
- There are five cases of blood vessel disorder in the adverse reaction database

AstraZeneca causes other side effects?
The European Medicines Agency (EMA) announced that it is investigating possible links between AstraZeneca against COVID-19 and cases of a rare blood vessel disease,
Five cases of a rare condition called capillary leak syndrome (capillary leak syndrome) have been reported in the EudraVigilance database, which reports the side effects of authorized medicines. This condition is characterized by blood leakage from the blood vessels, causing the tissues to swell and a drop in blood pressure.
At this stage, it is not yet clear whether there is a causal link between vaccination and the occurrence of these disorders. For now, we are dealing with a ‘safety signal’, that is, information about new adverse events that may be potentially related to the drug and which require further investigation.

The Safety Committee (PRAC) will assess all available data to see if there is a causal link. In cases where a causal relationship is confirmed or considered probable, regulatory action will be required to minimize the risk. This usually takes the form of an update of the product characteristics contained in the package insert.
Capillary leak syndrome – what is it?
Capillary leak syndrome (CLS), also known as Clarkson’s disease, causes blood to leak from small blood vessels into the muscles and cavities of the body.
This can cause blood pressure to drop suddenly and, if left untreated, organ failure.

Symptoms of this condition may include fatigue, fever, nausea, runny nose, cough, stomach pain, diarrhea and severe thirst.
It is very rare. According to the data of the American National Institutes of Health, it affects one person in a million a year. The cause of this condition is unknown, although in a few cases patients have previously reported a viral infection.
