Immunogenicity, reactogenicity, and safety of two-dose adjuvanted herpes zoster subunit vaccine in patients with systemic lupus erythematosus in South Korea: a single-centre, randomised, double-blind, placebo-controlled trial. THE LANCET. RHEUMATOLOGY 2024; 6:e352-e360. [PMID: 38710192 DOI: 10.1016/s2665-9913(24)00084-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/17/2024] [Revised: 03/14/2024] [Accepted: 03/19/2024] [Indexed: 05/08/2024]
Abstract
BACKGROUND The adjuvanted herpes zoster subunit vaccine has shown good efficacy and safety in the general population. However, its effectiveness has not been comprehensively assessed in patients with systemic lupus erythematosus (SLE). This study aimed to evaluate the immunogenicity and safety of the adjuvanted herpes zoster subunit vaccine in patients with SLE. METHODS This single-centre, randomised, double-blind, placebo-controlled, trial was done at the rheumatology outpatient clinic at Seoul National University Hospital, South Korea. Patients (aged ≥19 years) with clinically stable SLE and previous exposure (≥4 weeks) to immunosuppressive drugs were randomly assigned (4:1) via a central interactive web response system to receive herpes zoster subunit vaccine or placebo (0·5 mL intramuscular injection) at weeks 0 and 8. Investigators and participants were masked to intervention and group assignment. Anti-glycoprotein E antibody titres and glycoprotein E-specific cell-mediated vaccine responses were evaluated at baseline and at week 8 after the first dose, and at week 4, week 26, and week 52 after the second dose using enzyme-linked immunosorbent assay and flow cytometry, respectively. Reactogenicity, SLE disease activity, including Systemic Lupus Erythematosus Disease Activity Index 2000 and British Isles Lupus Assessment Group-flare rate, were examined. The primary outcome was the proportion of patients with a positive humoral vaccine response 4 weeks after the second dose. The primary and safety analyses were done in a modified intention-to-treat population. This study is registered with ClinicalTrials.gov, NCT06001606. FINDINGS Between June 14, and July 19, 2023, 65 patients with SLE were enrolled, of whom 52 were randomly assigned to the herpes zoster subunit vaccine and 13 to placebo. 49 patients in the vaccine group and 11 patients in the placebo group were included in the modified intention-to-treat population. 56 (93%) of 60 patients were women and four (7%) were men. Mean age was 48·7 years (SD 11·4). The proportion of participants with a humoral vaccine response at 4 weeks after the second dose was significantly higher in the vaccine group (48 [98%] of 49 participants) than the placebo group (none [0%] of 11 patients; p<0·0001). More patients in the vaccine group than placebo group reported injection site reactions (42 patients vs two patients), fever (ten vs none), and fatigue (26 vs two). There were no differences in Systemic Lupus Erythematosus Disease Activity Index 2000 and British Isles Lupus Assessment Group-flare rates between the groups. There were no treatment-related deaths. INTERPRETATION The herpes zoster subunit vaccine induces humoral and cellular immunity against herpes zoster with a good safety profile in patients with SLE. A larger study is warranted to assess the efficacy of vaccines to prevent herpes zoster in patients with SLE. FUNDING Ministry of Science and ICT, The Government of the Republic of Korea.

Park JK, Lee EB, Winthrop KL. What rheumatologists need to know about mRNA vaccines: current status and future of mRNA vaccines in autoimmune inflammatory rheumatic diseases. Ann Rheum Dis 2024; 83:687-695. [PMID: 38413167 DOI: 10.1136/ard-2024-225492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2024] [Accepted: 02/14/2024] [Indexed: 02/29/2024]
Abstract
Messenger RNA (mRNA) vaccines as a novel vaccine platform offer new tools to effectively combat both emerging and existing pathogens which were previously not possible. The 'plug and play' feature of mRNA vaccines enables swift design and production of vaccines targeting complex antigens and rapid incorporation of new vaccine constituents as needed. This feature makes them likely to be adopted for widespread clinical use in the future.Currently approved mRNA vaccines include only those against SARS-CoV-2 virus. These vaccines demonstrate robust immunogenicity and offer substantial protection against severe disease. Numerous mRNA vaccines against viral pathogens are in the early to late phase of development. Several mRNA vaccines for influenza are tested in clinical trials, with some already in phase 3 studies. Other vaccines in the early and late phases of development include those targeting Cytomegalovirus, varicella zoster virus, respiratory syncytial virus and Epstein-Barr virus. Many of these vaccines will likely be indicated for immunosuppressed populations including those with autoimmune inflammatory rheumatic diseases (AIIRD). This review focuses on the mechanism, safety and efficacy of mRNA in general and summarises the status of mRNA vaccines in development for common infectious diseases of particular interest for patients with AIIRD.

Butt IN, van Eeden C, Kovacs Burns K, Saxinger L, Clifford A, Redmond D, Cohen Tervaert JW, Yacyshyn E. Understanding COVID-19 vaccine hesitancy in vasculitis patients. Front Public Health 2023; 11:1301492. [PMID: 38111485 PMCID: PMC10726054 DOI: 10.3389/fpubh.2023.1301492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 11/13/2023] [Indexed: 12/20/2023] Open
Abstract
Objective To identify the factors that impact COVID-19 vaccine decision-making in vaccine-hesitant vasculitis patients, and compare their perceptions with other rheumatology patients, given existence of data suggesting rheumatology patients may have disease-specific factors that influence their COVID-19 vaccine decision-making. Methods This cross-sectional study surveyed adult rheumatology patients from the Kaye Edmonton Clinic Rheumatology Clinic, in Canada, between June and August 2021, using an anonymous online questionnaire. Survey responses were analyzed for statistical differences using chi-square analysis. Results The COVID-19 Vaccine Perceptions Survey had a response rate of 70.9%. Of the total 231 respondents, 103 patients were diagnosed with vasculitis. At the time of the survey, 10.6% of vasculitis patients refused to receive a COVID-19 vaccine compared to 6.3% for other rheumatology patients. Compared to other rheumatology patients, vaccine-hesitant vasculitis patients were significantly more concerned about almost every aspect of available COVID-19 vaccines [e.g., safety (p < 0.001), components (p < 0.001)], and feared that they could contract SARS-CoV-2 from a vaccine (p < 0.001). These vaccine-hesitant patients were also significantly less pleased with the government's pandemic response, less confident in healthcare team-provided information (p < 0.001), and more likely to report that healthcare providers had no role in their COVID-19 vaccine decision-making (p < 0.001). Conclusion Vaccine-hesitant vasculitis patients may have multiple considerations influencing COVID-19 vaccine hesitancy, including vaccine and disease-specific concerns, along with unfavorable perceptions of the healthcare system (government and healthcare providers). Healthcare providers can address some of these concerns by initiating patient-centered discussions around immunizations to help support educated decision-making.
