Accelerated waning of immunity to SARS-CoV-2 mRNA vaccines in patients with immune-mediated inflammatory diseases

Abstract

BACKGROUND Limited information is available on the impact of immunosuppressants on COVID-19 vaccination in patients with immune-mediated inflammatory diseases (IMID).METHODS This observational cohort study examined the immunogenicity of SARS-CoV-2 mRNA vaccines in adult patients with inflammatory bowel disease, rheumatoid arthritis, ankylosing spondylitis, or psoriatic disease, with or without maintenance immunosuppressive therapies. Ab and T cell responses to SARS-CoV-2, including neutralization against SARS-CoV-2 variants, were determined before and after 1 and 2 vaccine doses.RESULTS We prospectively followed 150 subjects, 26 healthy controls, 9 patients with IMID on no treatment, 44 on anti-TNF, 16 on anti-TNF with methotrexate/azathioprine (MTX/AZA), 10 on anti–IL-23, 28 on anti–IL-12/23, 9 on anti–IL-17, and 8 on MTX/AZA. Ab and T cell responses to SARS-CoV-2 were detected in all participants, increasing from dose 1 to dose 2 and declining 3 months later, with greater attrition in patients with IMID compared with healthy controls. Ab levels and neutralization efficacy against variants of concern were substantially lower in anti-TNF–treated patients than in healthy controls and were undetectable against Omicron by 3 months after dose 2.CONCLUSIONS Our findings support the need for a third dose of the mRNA vaccine and for continued monitoring of immunity in these patient groups.FUNDING Funded by a donation from Juan and Stefania Speck and by Canadian Institutes of Health (CIHR)/COVID-Immunity Task Force (CITF) grants VR-1 172711 and VS1-175545 (to THW and ACG), CIHR FDN-143250 (to THW), GA2-177716 (to VC, ACG, and THW), and GA1-177703 (to ACG) and the CIHR rapid response network to SARS-CoV-2 variants, CoVaRR-Net (to ACG).

(A) Spearman’s correlation at T3 between the indicated Ab levels determined by ELISA (y axis) and the neutralization of the WT spike lentivirus (x axis; see Supplemental Figure 4B for correlations with the VOCs). (B and C) Violin plots of log10 (ID50) — the serum dilution that inhibits 50% of the lentivirus infection — values of samples at B, T3 (2–4 weeks after dose 2), n = 129; and C, T4 (3 months after dose 2), n = 86. Lentiviral particles used: WT (Wuhan Hu-1 sequence with a D614G mutation); B.1.617.2 (Delta); B.1.351 (Beta); P.1 (Gamma); and B.1.1.529 (Omicron, BA.1). The distribution is stratified by study groups/treatments. The dots colors indicate the type of vaccine. Black lines indicate the median and the gray lines the mean ratio value for each violin. Comparisons were made by Dunn’s multiple comparisons test for the entire cohort. *P ≤ 0.05, **P ≤ 0.01, ***P ≤ 0.001, ****P ≤ 0.0001.
