Summary

This interventional phase IV clinical trial will evaluate the efficacy, immunogenicity and safety of the adjuvanted recombinant herpes zoster vaccine (RZV) in adults with autoimmune rheumatic diseases (ARDs) receiving immunomodulatory monotherapy. Humoral immune response will be quantified by anti-glycoprotein E (anti-gE) antibody titers. Patients will receive two doses of RZV. Outcomes include seroconversion and geometric mean titers six weeks after completion of the vaccination schedule, persistence of antibody titers at one year, and incidence of confirmed herpes zoster during follow-up.
