We undertook a self-controlled case series from 1 December 2020 to 24 April 2021 (the latest date for which outcome data were available) to examine the associations between ChAdOx1 nCoV-19 or BNT162b2 mRNA vaccines and thrombotic events during the ongoing covid-19 vaccination programme in England.
We also investigated the association between a SARS-CoV-2 positive test and the thrombotic events of interest among the same vaccinated population.
Table 1 shows the characteristics of 19 608 008 people who had the ChAdOx1 nCoV-19 vaccine, 9 513 625 who had the BNT162b2 mRNA vaccine,
and 1 758 095 with a SARS-CoV-2 positive test. During the study period, among those vaccinated, 9764 people had a hospital admission related to thrombocytopenia (52 deaths) and 23 390 people were admitted to hospital with venous thromboembolism (1871 deaths); this included 119 people with CVST related hospital admissions (no deaths). Hospital admission related to arterial thromboembolic events occurred in 89 321 people (6533 deaths); these included 28 222 ischaemic strokes (4204 deaths), 62 699 with myocardial infarction (2875 deaths), and 3655 with other rare arterial thrombotic events (84 deaths).
Table 2 shows the demographic characteristics of patients who experienced the primary outcomes of interest in the 28 days after exposure. Supplementary table 2 shows corresponding results for the secondary outcomes.
Objective To assess the association between covid-19 vaccines and risk of thrombocytopenia and thromboembolic events in England among adults. Design Self-controlled case series study using national data on covid-19 vaccination and hospital admissions. Setting Patient level data were obtained...
