In response to the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic, over 200 vaccine candidates against coronavirus disease 2019 (COVID-2019) are under development and currently moving forward at an unparalleled speed. The availability of surrogate endpoints would help to avoid large-scale filed efficacy trials and facilitate the approval of vaccine candidates, which is crucial to control COVID-19 pandemic. Several phase 3 efficacy trials of COVID-19 vaccine candidates are under way, which provide opportunities for the determination of COVID-19 correlates of protection. In this paper, we review current knowledge for existence of COVID-19 correlates of protection, methods for assessment of immune correlates of protection and issues related to COVID-19 correlates of protection.
针对严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)大流行,目前正在开发 200 多种针对 2019 年冠状病毒病(COVID-19)的疫苗候选物,其推进速度前所未有。替代终点的出现将有助于避免大规模的现场疗效试验,并促进疫苗候选物的批准,这对于控制 COVID-19 大流行至关重要。目前正在进行几项 COVID-19 疫苗候选物的 3 期疗效试验,为确定 COVID-19 保护相关因素提供了机会。在本文中,我们回顾了 COVID-19 保护相关因素的现有知识、评估免疫保护相关因素的方法以及与 COVID-19 保护相关因素相关的问题。
