Various diseases associated with COVID-19 vaccines have been reported. A recent case study indicated that COVID-19 vaccination may trigger the development of anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitis, potentially damaging multiple organs. Among 29 patients, five underwent plasmapheresis treatment (the separation and replacement of plasma from blood), and five relied on dialysis therapy.
ANCA-associated vasculitis can cause damage to small blood vessels. Since these are distributed throughout the body, any part of the body can be affected, with the most common areas being the lungs, kidneys, joints, ears, nose, and nerves.
