Vaccines against SARS-CoV-2 are known to be less immunogenic for some individuals, whereas others present notably high levels of antibody production. We assessed the cellular response to BNT162b2 among individuals with low post-vaccination antibody levels as well as in a small group of individuals with high titers. Antibody levels were assessed by the Abbott SARS-CoV-2 IgG II Quant assay. The interferon-γ production of T-cells in response to SARS-CoV-2 antigens was determined using Qiagen's QuantiFERON SARS-CoV-2 ELISA test. Our results showed that participants with high antibody levels presented adequate cellular response in all studied cases, whereas those with low antibody levels generally showed limited to almost absent cellular response five months post vaccination.
已知针对 SARS-CoV-2 的疫苗对某些个体的免疫原性较低，而另一些个体则产生明显高水平的抗体。我们评估了 BNT162b2 在抗体水平低的个体以及少数高滴度个体中的细胞反应。抗体水平通过 Abbott SARS-CoV-2 IgG II Quant 测定法评估。使用 Qiagen 的 QuantiFERON SARS-CoV-2 ELISA 测试来确定 T 细胞对 SARS-CoV-2 抗原的干扰素-γ产生情况。我们的结果表明，在所有研究病例中，高抗体水平的参与者均表现出充分的细胞反应，而抗体水平低的参与者在接种疫苗五个月后通常表现出有限至几乎不存在的细胞反应。
