In efforts to synthesize a clear understanding of SARS-CoV-2 protective immunity, antibody analysis has been paralleled by T cell studies across asymptomatic, mild and severe COVID-19. Defining CD4 and CD8 effector functions in protection is important considering that antibody responses appear short-lived and T cell memory is potentially more durable. To fully understand population level immunity, screening for both antibody and T cell immunity using standardized testing methods would be beneficial.

SARS-CoV-2 T细胞免疫力：特异性，功能，耐用性和保护作用。

为了对SARS-CoV-2保护性免疫产生清晰的理解，抗体分析与无症状，轻度和严重COVID-19的T细胞研究同时进行。考虑到抗体应答的寿命很短，而T细胞的记忆力可能更持久，因此定义CD4和CD8效应子的保护功能非常重要。为了充分了解人群水平的免疫力，使用标准化测试方法筛查抗体和T细胞免疫力将是有益的。
