Summary

This study tested whether giving a stronger or extra dose of the pneumococcal vaccine could improve immune protection in 96 adults with ANCA-associated vasculitis who are taking rituximab. Participants received either the standard vaccine schedule or one of two reinforced schedules. The goal was to see if the stronger strategies produce a better immune response without increasing side effects.
