Can flu shots protect autoimmune patients?
NCT ID NCT01065285
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at how well flu vaccines (seasonal and H1N1) work in 234 adults with autoimmune diseases like lupus or vasculitis, some of whom were on steroids or immunosuppressants. Researchers measured antibody levels three weeks after each shot to see if the vaccine provided protection. The goal was to understand if these patients can safely and effectively benefit from flu vaccination.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Influenza vaccine (seasonal and H1N1)
- What this could lead to
- If successful, this could show that flu vaccines are effective and safe for people with autoimmune diseases, even those on strong medications.
- What could go wrong
- This is a completed Phase 4 study, so results are known but may not apply to all autoimmune conditions. The immune response may be weaker in patients on immunosuppressants.
