abstract = {The self-controlled case series (SCCS) is a study design used in epidemiology to test for variation in outcomes for a group of individuals before and after an exposure or intervention, with each pre-intervention individual serving as a control for themselves in the post-intervention period. The design is particularly useful for studying rare events or outcomes that occur in a time-dependent manner, such as uncommon side-effects of a medical intervention [1–3]. In the Early Pandemic Evaluation and Enhanced Surveillance of COVID-19 (EAVE II) study, we used this SCCS design to evaluate the safety of coronavirus disease 2019 (COVID-19) vaccines in various age groups of the Scottish and UK populations.},
