The response of vasculitis patients to influenza vaccination compared to healthy individuals

Patients with ANCA (Anti-neutrophil cytoplasmic antibodies) vasculitis and healthy individuals were recruited to assess their response to influenza vaccination. It was anticipated that the the response to the vaccine by the patients would be less than the healthy control group, but still sufficient to provide protection against the influenza virus. The response of healthy individuals and those with ANCA vasculitis will be compared. Patients with ANCA vasculitis were monitored throughout the study to determine whether the influenza vaccination caused any change in their disease activity.
