Clinical Trial Summary

COVID-19 vaccines induced malaise have recently been reported in the literature. Our study aims to identify risk factors associated with the onset of COVID-19 vaccines induced malaise and to assess if certain COVID-19 vaccines could be more prone to cause malaise compared to influenza vaccines. To do so we performed a disproportionality analysis adjusted on age class, sex, region and type of reporter in VigiBase®, the WHO pharmacovigilance database, restricted to data from 01/01/2021 to 26/01/2022 to assess the association between all COVID-19 vaccines on the market and malaise. Demographic data were also analyzed.
