Humoral and cellular immune responses after standard two-dose COVID-19 vaccination are reduced in immunosuppressed patients with antineutrophil cytoplasmic antibodies associated vasculitis (AAV).1–3 Emerging variants such as B.1.617.2 (delta) are of particular concern because of their higher transmissibility and partial immune escape.4 AAV patients with lower neutralising antibody levels may become particularly susceptible to these variants of concern and additional booster vaccination may be required.
