Vasculitis as an adverse event following immunization – Systematic literature review

Highlights • The literature review showed numerous reports of vasculitides following vaccination with a limited number of controlled studies. • Vasculitis were more frequently reported in association with influenza vaccines. • Only 24% of the articles reported using a case definition of vasculitis. • Existing literature does not allow establishing a causative link between vaccination and vasculitides. • Developing standard case definitions for specific vasculitides could improve the overall data quality and comparability.
