    Abstract

    SARS-CoV-2, the causal agent of COVID-19, first emerged in late 2019 in China. It has since infected more than 170,000 individuals and caused more than 6500 deaths globally. Here we discuss therapeutic and prophylactic interventions for SARS-CoV-2 with a focus on vaccine development and its challenges. Vaccines are being rapidly developed but will likely come too late to have an impact on the first wave of a potential pandemic. Nevertheless, important lessons can be learned for the development of vaccines against rapidly emerging viruses. Importantly, SARS-CoV-2 vaccines will be essential to reducing morbidity and mortality if the virus establishes itself in the population.

    • Structural basis for neutralization of SARS-CoV-2 and SARS-CoV by a potent therapeutic antibody Zhe Lv1,8,*, Yong-Qiang Deng2,*, Qing Ye2,*, Lei Cao1,*, Chun-Yun Sun3,*, Changfa Fan4,*, Weijin Hua Science 23 Jul 2020: eabc5881 DOI: 10.1126/science.abc5881 Abstract The COVID-19 pandemic caused by the SARS-CoV-2 virus has resulted in an unprecedented public health crisis. There are no approved vaccines or therapeutics for treating COVID-19. Here we reported a humanized monoclonal antibody, H014, efficiently neutralizes SARS-CoV-2 and SARS-CoV pseudoviruses as well as authentic SARS-CoV-2 at nM level by engaging the S receptor binding domain (RBD). Importantly, H014 administration reduced SARS-CoV-2 titers in the infected lungs and prevented pulmonary pathology in hACE2 mouse model. Cryo-EM characterization of the SARS-CoV-2 S trimer in complex with the H014 Fab fragment unveiled a novel conformational epitope, which is only accessible when the RBD is in open conformation. Biochemical, cellular, virological and structural studies demonstrated that H014 prevents attachment of SARS-CoV-2 to its host cell receptors. Epitope analysis of available neutralizing antibodies against SARS-CoV and SARS-CoV-2 uncover broad cross-protective epitopes. Our results highlight a key role for antibody-based therapeutic interventions in the treatment of COVID-19.
