Safety of Recombinant Zoster Vaccine in Rheumatology Patients.

Objectives: Recombinant zoster vaccine (RZV) is Food and Drug Administration approved for the prevention of herpes zoster (shingles) in adults 50 years old and older. Immunocompromised subjects were excluded from the pivotal vaccine trials. We studied the safety of this vaccine in our university-affiliated rheumatology practice.
Methods: This was a single-center, retrospective study focusing on subjects who received RZV during 2018. We collected the demographic data, any self-reported adverse events after vaccination, C-reactive protein, Routine Assessment of Patient Index Data 3 (RAPID3) scores for subjects with rheumatoid arthritis, and available RAPID3 scores for all study subjects before and after the vaccination.
Results: Comparision of C-reactive protein (n = 40), RAPID3 scores for subjects with rheumatoid arthritis (n = 16), and available RAPID3 scores for all subjects (n = 21) using the paired t test, did not show significant differences before and after the administration of RZV. A total of 6.4% of patients reported adverse events after vaccination. The adverse events were mild and did not lead to hospitalization, end organ damage, or change in treatment plan.
Conclusions: The RZV was safe and well tolerated among our study population.
