Four cases of acquired hemophilia A following immunization with mRNA BNT162b2 SARS-CoV-2 vaccine
Age-Stratified Risk of Cerebral Venous Sinus Thrombosis After SARS-CoV-2 Vaccination
...In recipients of ChAdOx1 nCov-19, the absolute risk of CVST, both with and without thrombocytopenia, was the highest in the 18- to 24-year-old group (7.3 per million, 95% CI 2.8–18.8 and 3.7 per million, 95% CI 1.0–13.3, respectively). The risk of CVST with thrombocytopenia in ChAdOx1 nCov-19 recipients was the lowest in the age group ≥70 years (0.2, 95% CI 0.0–1.3). Age <60 years compared to ≥60 years was a predictor for CVST with thrombocytopenia (incidence rate ratio 5.79, 95% CI 2.98–11.24, p < 0.001).
