Humoral and cellular responses are critical in understanding immune responses to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination. Here, we evaluated these responses in hemodialysis (HD) patients after the booster vaccination. SARS-CoV-2 immunoglobulin (IgG) levels, neutralizing antibody titers, and the T-SPOT.COVID test (T-SPOT) were measured prior to, three weeks after, and three months after the booster administration. The HD group had significantly higher SARS-CoV-2 IgG levels and neutralizing antibody titers against the original strain at three weeks and three months after the booster vaccination compared to the control group, albeit the HD group had lower SARS-CoV-2 IgG levels and neutralizing antibody titers before the booster administration. Moreover, the HD group had significantly higher T-SPOT levels at all three time points compared to the control group. The HD group also had significantly higher local and systemic adverse reaction rates than the control group. By booster vaccination, HD patients could acquire more effective SARS-CoV-2-specific humoral and cellular immunity than the control group.
体液和细胞免疫反应对于理解严重急性呼吸综合征冠状病毒2(SARS-CoV-2)疫苗接种后的免疫反应至关重要。在此,我们评估了血液透析(HD)患者在加强疫苗接种后的这些反应。在加强疫苗接种前、接种后三周和三个月时测量了SARS-CoV-2免疫球蛋白(IgG)水平、中和抗体滴度以及T-SPOT.COVID检测(T-SPOT)。与对照组相比,HD组在加强疫苗接种后三周和三个月时针对原始毒株的SARS-CoV-2 IgG水平和中和抗体滴度显著更高,尽管HD组在加强疫苗接种前的SARS-CoV-2 IgG水平和中和抗体滴度较低。此外,HD组在所有三个时间点的T-SPOT水平均显著高于对照组。HD组的局部和全身不良反应发生率也显著高于对照组。通过加强疫苗接种,HD患者比对照组能获得更有效的SARS-CoV-2特异性体液和细胞免疫。
