Objective: The aim of this study was to investigate a possible relationship between the time onset (TTO) adverse events following immunization (AEFIs) and recall bias compare it AEFIs COVID-19 vaccines reported though spontaneous reporting system (SRS) those from cohort event monitoring (CEM) study. Methods: A retrospective comparing TTO patterns four SRS CEM performed. Reports concerning related vaccination were used for stratified dose number, perceived burden AEFI, being pre-defined. Additionally, since menstrual disorders received much media attention, their effect on pattern investigated reports only. Results: total 160,613 19,979 CEM, containing 755,647 103,703 AEFIs, respectively, included. For with short TTO, no differences in observed. However, median lower increasing duration. There both before during episodes but correlation two could be found. Conclusions: Based performed analyses, does not seem more evident compared studies TTO. longer may pronounced.
