全球范围内出现的许多严重急性呼吸综合征冠状病毒2(SARS-CoV-2)变异体危及感染或接种疫苗后诱导的保护性抗病毒免疫。为了解决日益增加的SARS-CoV-2基因组多样性造成的公共卫生威胁,美国国立卫生研究院(NIH)下属的国家过敏和传染病研究所(NIAID)建立了SARS-CoV-2病毒进化评估(SAVE)计划。这项工作旨在提供对SARS-CoV-2变体的实时风险评估,这些变体可能影响传播,毒力以及对恢复期和疫苗诱导免疫的抗性。SAVE项目是美国政府SARS-CoV-2跨部门小组的关键数据生成组件,以评估SARS-CoV-2变异对诊断、疫苗和治疗的影响,并传达公共卫生风险。在这里,我们描述了用于识别和管理有关新出现的变异的数据的协调方法,它们对免疫力的影响,以及使用动物模型对疫苗保护的影响。我们报告的试剂,方法,模型和关键的研究结果促进了这种合作的方法,并确定未来的挑战。该计划通过监测病毒在人群中的演变,以确定可能削弱对策有效性的变异,作为应对快速演变的大流行病原体的模板。
The global emergence of many severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants jeopardizes the protective antiviral immunity induced following infection or vaccination. To address the public health threat caused by the increasing SARS-CoV-2 genomic diversity, the National Institute of Allergy and Infectious Diseases (NIAID) within the National Institutes of Health (NIH) established the SARS-CoV-2 Assessment of Viral Evolution (SAVE) program. This effort was designed to provide a real-time risk assessment of SARS-CoV-2 variants potentially impacting transmission, virulence, and resistance to convalescent and vaccine-induced immunity. The SAVE program serves as a critical data-generating component of the United States Government SARS-CoV-2 Interagency Group to assess implications of SARS-CoV-2 variants on diagnostics, vaccines, and therapeutics and for communicating public health risk. Here we describe the coordinated approach used to identify and curate data about emerging variants, their impact on immunity, and effects on vaccine protection using animal models. We report the development of reagents, methodologies, models, and pivotal findings facilitated by this collaborative approach and identify future challenges. This program serves as a template for the response against rapidly evolving pandemic pathogens by monitoring viral evolution in the human population to identify variants that could erode the effectiveness of countermeasures.
