Résumé
Cellular immune defects associated with suboptimal responses to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccination in people receiving hemodialysis (HD) are poorly understood. We longitudinally analyze antibody, B cell, CD4 <sup>+</sup> , and CD8 <sup>+</sup> T cell vaccine responses in 27 HD patients and 26 low-risk control individuals (CIs). The first two doses elicit weaker B cell and CD8 <sup>+</sup> T cell responses in HD than in CI, while CD4 <sup>+</sup> T cell responses are quantitatively similar. In HD, a third dose robustly boosts B cell responses, leads to convergent CD8 <sup>+</sup> T cell responses, and enhances comparatively more T helper (T <sub>H</sub> ) immunity. Unsupervised clustering of single-cell features reveals phenotypic and functional shifts over time and between cohorts. The third dose attenuates some features of T <sub>H</sub> cells in HD (tumor necrosis factor alpha [TNFα]/interleukin [IL]-2 skewing), while others (CCR6, CXCR6, programmed cell death protein 1 [PD-1], and HLA-DR overexpression) persist. Therefore, a third vaccine dose is critical to achieving robust multifaceted immunity in hemodialysis patients, although some distinct T <sub>H</sub> characteristics endure.
