[Intracerebral haemorrhage twelve days after vaccination with ChAdOx1 nCoV-19].

The COVID-19-pandemic has had a huge impact on health and economics all over the world resulting in widespread vaccine development. Vaccine-induced immune thrombotic thrombocytropenia has been described, suggesting a link between the two adeno-vector vaccines ChAdOx1 nCoV-19 (Vaxzevria from AstraZeneca) and Ad26.COV2-S (Janssen from Johnson and Johnson). This rare clinical condition should be suspected in patients with headache, abdominal pain, suspected thrombosis or hemorrhage and thrombocytopenia within 3-30-day post vaccine. In this case report a previously healthy man had thrombocytopenia with fatal intracerebral haemorrhage which was suspected to be related to vaccine.
