Some countries in the European Union have temporarily suspended use of the AstraZeneca COVID-19 vaccine as a precautionary measure based on reports of rare blood coagulation disorders in persons who had received the vaccine. Other countries in the EU – having considered the same information - have decided to continue using the vaccine in their immunization programmes. 

Vaccination against COVID-19 will not reduce illness or deaths from other causes. Thromboembolic events are known to occur frequently. Venous thromboembolism is the third most common cardiovascular disease globally. 

In extensive vaccination campaigns, it is routine for countries to signal potential adverse events following immunization. This does not necessarily mean that the events are linked to vaccination itself, but it is good practice to investigate them. It also shows that the surveillance system works and that effective controls are in place.
