This is the code list that was used to identify outcomes and covariates (those tagged as in narrow) in electronic health records of participating data sources in the the CVM study which was addressing the following questions 1) To create and assess readiness of electronic health record data sources for rapid evaluation of safety signals by Providing an overview of the methods for identification of COVID-19 vaccine exposure in the data sources Monitoring the number of individuals exposed to any COVID-19 vaccine and to compare this to COVID-19 vaccine exposure (benchmark: ECDC vaccine tracker)1 Generation of updated background rates for AESIs 2) To conduct rapid safety assessment studies using electronic healthcare records and support EMA safety assessments. The protocol for this study is publicly available www.encepp.eu/encepp/viewResource.htm?id=42637. The report with results using the code list is publicly available on Zenodo as well.
