From the article:

Compared to the status of 11.03.2021, additional cases (as of Monday, 15.03.2021) have now been reported in Germany. In the analysis of the new data status, the experts of the Paul Ehrlich Institute now see a striking accumulation of a special form of very rare cerebral vein thrombosis (sinus vein thrombosis) in conjunction with a deficiency of blood platelets (thrombocytopenia) and bleeding in temporal proximity to vaccinations with the COVID-19 vaccine AstraZeneca.
