The impact of coronavirus-19 vaccination on anti-nuclear cytoplasmic antibody vasculitis hospitalisations in a Sydney health network.

Publication date: Feb 25, 2024

There have been reports of COVID-19 vaccination triggering anti-nuclear cytoplasmic antibody (ANCA)-associated vasculitis (AAV), but no robust studies have examined the link. This retrospective cohort study assessed the impact of COVID vaccination on the rate of denovo and relapsed AAV in a Sydney Local Health District from 2018 to 2022. Despite more than 95% of the population receiving vaccination, the case rate of AAV was stable. These findings do not support a relationship between COVID vaccination and AAV.
