Reporting rate for TTS and TTS fatality rate following AZD1222 vaccination by regions and countries EEA=European Economic Area. TTS=thrombosis with thrombocytopenia syndrome. Background TTS rate estimated in an unvaccinated prepandemic population using the US Truven MarketScan Commercial Claims and Encounters database. In method 1 for calculation of background TTS rate, TTS was defined as primary or unspecified thrombocytopenia occurring between 7 days before and 7 days after a thrombosis event (focused on thrombosis of limbs, splanchnic region, and cerebral or pulmonary embolism), restricted to patients without a history of thrombocytopenia or thrombotic event in the previous 12 months; in method 2, TTS was defined as primary or unspecified thrombocytopenia occurring the day before, or 14 days after, thrombosis. Exposure data from the EEA, Australia, the UK, Canada, Asian countries and Brazil are from data-lock point (Aug 31, 2021). *Nordic countries are Denmark, Finland, Iceland, Norway, and Sweden. †EEA includes the Nordic countries. ‡Asian countries included are the Philippines, South Korea, and Taiwan.
