Antineutrophil cytoplasmic autoantibodies associated vasculitis(AAV) is
characterized by antibodies against antigens in cytoplasmic granules of
neutrophils and predominantly affects small vessels. AAV after COVID-19
mRNA vaccination has been reported. We report rare case of AAV in a
patient who presented with rapidly progressive glomerulonephritis(RPGN)
after Johnson & Johnson vaccine administration.
