NCT ID NCT00611663

First seen Nov 01, 2025 · Last updated Jun 19, 2026 · Updated 30 times

Summary

This study tested two different pneumococcal vaccination strategies in 47 adults with stable lupus. One group received a prime-boost approach with a conjugate vaccine followed by a polysaccharide vaccine six months later; the other got a placebo then the standard polysaccharide vaccine. The goal was to see which strategy produced a stronger immune response without worsening lupus symptoms.
