Gen et al.: Is there risk of ANCA-Associated Vasculitis after Moderna COVID mRNA Vaccination? Yes, case in point, see this myeloperoxidase antineutrophil cytoplasmic antibody (MPO-ANCA)-associated

vasculitis after vaccination; 82-year-old woman developed pyrexia & general malaise one month after her third booster vaccine & the symptoms persisted. Blood testing revealed inflammation, high level

of MPO-ANCA, and microscopic hematuria.’

‘experienced a case of myeloperoxidase antineutrophil cytoplasmic antibody (MPO-ANCA)-associated vasculitis after Moderna COVID-19 vaccination.

82-year-old woman developed pyrexia and general malaise one month after her third booster vaccine, and the symptoms persisted. Blood testing revealed inflammation, a high level of MPO-ANCA, and microscopic hematuria. MPO-ANCA-associated vasculitis was diagnosed by renal biopsy. The symptoms improved with steroid therapy. Common adverse reactions to mRNA vaccines against COVID-19 include pyrexia and general malaise, but MPO-ANCA-associated vasculitis can also occur. If pyrexia, prolonged general malaise, urinary occult blood, or renal impairment is observed, the onset of MPO-ANCA-associated vasculitis should be considered.’
