The emergence and explosive spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in 2019 highlighted the need to rapidly develop curated biobanks to inform the etiology, diagnosis, and treatment options for global outbreaks of communicable diseases. Recently, we undertook efforts to develop a repository of biospecimens from individuals aged 12 and older who were to be vaccinated against coronavirus disease 19 (COVID-19) with vaccines developed with support from the United States Government. We planned to establish 40 or more clinical study sites in at least six countries to collect biospecimens from 1,000 individuals, 75% of whom were to be SARS-CoV-2 naive at the time of enrollment. Specimens would be used to (i) ensure quality control of future diagnostic tests, (ii) understand immune responses to multiple COVID-19 vaccines, and (iii) provide reference reagents for the development of new drugs, biologics, and vaccines. Biospecimens included serum, plasma, whole blood, and nasal secretions. Large-volume collections of peripheral blood mononuclear cells (PBMCs) and defibrinated plasma were also planned for a subset of subjects. Participant sampling was planned at intervals prior to and following vaccination over a 1-year period. Here, we describe the selection of clinical sites for specimen collection and processing, standard operating procedure (SOP) development, design of a training program for tracking specimen quality, and specimen transport to a repository for interim storage. This approach allowed us to enroll our first participants within 21 weeks from the study's initiation. Lessons learned from this experience should benefit the development of biobanks in response to future global epidemics. The ability to rapidly create a biobank of high-quality specimens in response to emergent infectious diseases is critical to allow for the development of prevention and treatment, as well as to effectively monitor the spread of the disease. In this paper, we report on a novel approach to getting global clinical sites up and running within a short time frame and to monitor the quality of specimens collected to ensure their value in future research efforts. Our results have important implications for the monitoring of the quality of biospecimens collected and to design effective interventions to address shortcomings, where needed.
2019 年,严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)的出现和爆炸性传播凸显了迅速开发经过精心整理的生物库的必要性,以便为传染病的全球爆发提供病因、诊断和治疗选择方面的信息。最近,我们努力开发一个生物样本库,其中包含年龄在 12 岁及以上的个人的生物样本,这些人将接种由美国政府支持开发的 2019 年冠状病毒病(COVID-19)疫苗。我们计划在至少六个国家建立 40 个或更多的临床研究点,从 1000 名个人中收集生物样本,其中 75%的人在入组时对 SARS-CoV-2 是无免疫力的。这些样本将用于:(i)确保未来诊断测试的质量控制;(ii)了解对多种 COVID-19 疫苗的免疫反应;(iii)为开发新药物、生物制剂和疫苗提供参考试剂。生物样本包括血清、血浆、全血和鼻腔分泌物。还计划为一部分对象采集大量外周血单核细胞(PBMC)和去纤维蛋白血浆。在 1 年的时间里,在接种疫苗前后的间隔内计划对参与者进行采样。在这里,我们描述了为样本采集和处理选择临床地点、制定标准操作程序(SOP)、设计跟踪样本质量的培训计划以及将样本运输到临时存储库的情况。这种方法使我们能够在研究开始后的 21 周内招募第一批参与者。从这次经验中吸取的教训应该有助于应对未来全球流行病的生物库的发展。能够快速创建针对新发传染病的高质量生物样本库对于制定预防和治疗措施以及有效监测疾病的传播至关重要。在本文中,我们报告了一种新方法,可以在短时间内使全球临床地点投入运行,并监测所采集样本的质量,以确保它们在未来的研究工作中具有价值。我们的结果对于监测所采集生物样本的质量以及设计有效的干预措施以解决需要解决的不足之处具有重要意义。
