The benefits of using AstraZeneca to prevent Covid-19 outweigh the risk of side effects, the European Medicines Agency announced on Wednesday, confirming that blood clots should be listed as very rare side effects of this preparation.

President of the Agency, Michał Kuczmierowski, added that it was important that all institutions that manage the vaccination process constantly monitor the situation regarding vaccines from all producers.

Kuczmierowski emphasized that the entire vaccination process was supervised by relevant institutions - the Office for Registration of Medicinal Products, the Chief Sanitary Inspectorate, the Chief Pharmaceutical Inspectorate, which watch over the safety of vaccines and monitor the situation in detail.
