Project Summary This revised application was originally responding to the Emergency Award ‘Rapid Investigation of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and Coronavirus Disease 2019 (COVID-19)’ submitted through PAR-20-177. However, we are submitting the revised application, upon advice from NIH, to the parent PA-20-195 with a due date of Nov 16th 2020. The application is titled ‘Development of Broad Coronavirus Immunity Targeting the Fusion Peptide’. The assembled team brings together highly complementary expertise in order to develop a unique coronavirus vaccine approach to provide more effective, focused and broadened humoral immunity. This proposal focuses on the fusion peptide site of vulnerability as it has been understudied, it is highly conserved and recently been identified as an epitope of neutralizing antibodies in human convalescent sera. The project aims are: (1) Develop pan- coronavirus fusion peptide nanoparticle and trimer immunogens (2) Develop immunization regimes to induce broadly neutralizing antibodies using nucleic acid delivery.

项目摘要 这一修改后的申请最初是为了响应紧急奖的快速调查严重 非典型肺炎冠状病毒2(SARS-CoV-2)和冠状病毒病2019(新冠肺炎)‘ 通过PAR-20-177提交。然而，根据NIH的建议，我们将修改后的申请提交给 亲本PA-20-195，到期日为2020年11月16日。这项申请的标题是‘发展的远大 针对融合多肽的冠状病毒免疫。集结的团队高度团结在一起 互补专业知识，以开发一种独特的冠状病毒疫苗方法，以提供更有效、 集中和扩大了体液免疫。这项建议集中在融合多肽的位置 脆弱性由于研究不足，它是高度保守的，最近被确定为 人恢复期血清中和抗体的表位。该项目的目标是：(1)发展泛欧 冠状病毒融合多肽纳米粒和三聚体免疫原(2)发展免疫机制以诱导 使用核酸递送广泛中和抗体。
