To inform the ongoing discussion on the safety of the Oxford-AstraZeneca COVID-19 vaccine, we analysed nationwide population-based data from Denmark to estimate the natural incidence of venous thromboembolism. 5 Denmark has a tax-supported universal health-care system, In recent weeks there have been concerns about blood clots occurring in patients after they were given the AstraZeneca vaccine.(1) Most reports involved women under 55 years.(2) These reports included 18 cases of cerebral venous sinus thrombosis (as of 17 March 2021).(3 Early observations insinuate that the exposure to the COVID-19 vaccine AstraZeneca might trigger the expression of antiplatelet antibodies, resulting in a condition with thrombocytopenia and venous thrombotic events (e.g., intracranial venous sinus thrombosis). These patients' treatment should add Since the first reports of blood clotting after the AstraZeneca vaccine emerged in March 2021, our understanding of the clotting disorder, called vaccine-induced thrombotic thrombocytopaenia (VITT)..
