Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immune responses and infection outcomes were evaluated in 2,686 patients with varying immune-suppressive disease states after administration of two Coronavirus Disease 2019 (COVID-19) vaccines. Overall, 255 of 2,204 (12%) patients failed to develop anti-spike antibodies, with an additional 600 of 2,204 (27%) patients generating low levels (<380 AU ml). Vaccine failure rates were highest in ANCA-associated vasculitis on rituximab (21/29, 72%), hemodialysis on immunosuppressive therapy (6/30, 20%) and solid organ transplant recipients (20/81, 25% and 141/458, 31%). SARS-CoV-2-specific T cell responses were detected in 513 of 580 (88%) patients, with lower T cell magnitude or proportion in hemodialysis, allogeneic hematopoietic stem cell transplantation and liver transplant recipients (versus healthy controls). Humoral responses against Omicron (BA.1) were reduced, although cross-reactive T cell responses were sustained in all participants for whom these data were available. BNT162b2 was associated with higher antibody but lower cellular responses compared to ChAdOx1 nCoV-19 vaccination. We report 474 SARS-CoV-2 infection episodes, including 48 individuals with hospitalization or death from COVID-19. Decreased magnitude of both the serological and the T cell response was associated with severe COVID-19. Overall, we identified clinical phenotypes that may benefit from targeted COVID-19 therapeutic strategies.
评估了 2686 名患有不同免疫抑制性疾病的患者在接种两种 2019 年冠状病毒病(COVID-19)疫苗后的严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)免疫反应和感染结果。总体而言,2204 名患者中有 255 名(12%)未能产生抗刺突抗体,另外 2204 名患者中有 600 名(27%)产生低水平抗体(<380 AU/ml)。在利妥昔单抗治疗的抗中性粒细胞胞质抗体相关性血管炎(21/29,72%)、免疫抑制治疗的血液透析(6/30,20%)和实体器官移植受者中,疫苗失败率最高(20/81,25%和 141/458,31%)。在 580 名患者中的 513 名(88%)患者中检测到 SARS-CoV-2 特异性 T 细胞反应,与健康对照组相比,血液透析、异基因造血干细胞移植和肝移植受者的 T 细胞数量或比例较低。针对奥密克戎(BA.1)的体液反应降低,尽管对于所有有这些数据的参与者,交叉反应性 T 细胞反应仍然持续。与 ChAdOx1 nCoV-19 疫苗相比,BNT162b2 接种后抗体水平较高,但细胞反应较低。我们报告了 474 例 SARS-CoV-2 感染病例,包括 48 例因 COVID-19 住院或死亡的患者。血清学和 T 细胞反应幅度的降低与严重 COVID-19 相关。总的来说,我们确定了可能受益于靶向 COVID-19 治疗策略的临床表型。
