How the Pfizer COVID-19 vaccine affects people with lupus or scleroderma

Mechanisms of BNT162b2 Vaccine Immunogenicity in Systemic Lupus Erythematosus or Scleroderma

NIH-funded research Stanford University · NIH-11262193

This project looks at immune responses to the Pfizer (BNT162b2) COVID-19 vaccine in people with lupus or scleroderma to understand why some have weaker protection.

What this research studies

You would be followed over time while receiving the Pfizer COVID-19 vaccine and asked to give blood samples at set visits. Researchers will measure your antibodies, neutralizing activity against virus variants, vaccine-specific T cells, and key signaling proteins using detailed single-cell and protein tests. The team will compare people who make strong responses to those who do not, including how medications for autoimmune disease affect vaccine responses. Results aim to explain why some patients have lower protection and how responses change over months.

Who could benefit from this research

Good fit: Adults diagnosed with systemic lupus erythematosus (SLE) or systemic sclerosis (scleroderma) who can attend clinic visits and provide blood samples during the vaccination series are ideal candidates.

Not a fit: People without these connective tissue diseases or those seeking an immediate therapeutic treatment likely will not receive direct clinical benefit from this mechanistic study.

Why it matters

Potential benefit: If successful, this work could help doctors predict who might have weaker vaccine protection and guide better vaccination or treatment plans for people with lupus or scleroderma.

How similar studies have performed: Earlier smaller work by the team in 18 lupus patients found variable antibody and T cell responses and identified immune signals linked to nonresponse, but larger longitudinal cohorts are needed to confirm and expand those findings.
