Study description

Readiness The readiness phase will include the following objectives: • To provide an overview of the methods for identification of COVID-19 vaccine exposure in the data sources • To monitor the number of individuals exposed to any COVID-19 vaccine and to compare this to COVID-19 vaccine exposure data • To quantitatively evaluate different algorithms to identify adverse events by provenance in electronic health care data • To conduct time-to-onset analyses for the AESI with respect to time since vaccination • To assess the association between and the vaccines of interest and negative control events using the SCRI to estimate systematic bias (unmeasured confounding) • To test the impact of different comparators in the cohort design, using the negative control outcomes • To generate information for testing of methodological questions around misclassification of events/exposure Rapid assessment studies Primary objective The primary objective for this rapid assessment study is to assess the potential association between the occurrence of specific AESIs and vaccination with COVID-19 vaccines within disease-specific risk periods in individuals exposed to the COVID-19 vaccines compared to other COVID-19 vaccine exposed individuals or compared to a control window within the same individual. Secondary objectives The secondary objectives for the rapid assessments studies are: • To assess the potential association between the occurrence of specific AESIs and vaccination with COVID-19 vaccines in the following subgroups o immunocompromised persons o persons with the presence of co-morbidities elevating the risk of serious COVID-19 o persons with a history of diagnosed COVID-19 disease o pregnant women o age groups o patients with a prior history (ever) of that event more than a year before. Study design: A retrospective, multi-database, self-controlled risk interval or cohort study
