全球对抗COVID-19大流行的努力导致数百种候选疫苗进入不同的研发阶段,包括处于第一、第二和第三阶段临床试验的几种疫苗。在SARS-CoV-2疾病模型中评价的这些疫苗数量相对较少,在严重疾病模型中评价的疫苗数量较少。在这里,靶向刺突蛋白并通过喷射注射递送的SARS-CoV-2 DNA nCoV-S(JET)在仓鼠中引发中和抗体,并且在野生型和瞬时免疫抑制仓鼠模型中均具有保护性。这项研究强调了我们开发的DNA疫苗nCoV-S(JET)具有进入下一阶段临床前研究的巨大潜力,并且它还证明了短暂免疫抑制的叙利亚仓鼠,其重现了严重和长期的COVID-19疾病,可用于临床前评估基于加标的COVID-19疫苗的保护效力。
A worldwide effort to counter the COVID-19 pandemic has resulted in hundreds of candidate vaccines moving through various stages of research and development, including several vaccines in phase 1, 2 and 3 clinical trials. A relatively small number of these vaccines have been evaluated in SARS-CoV-2 disease models, and fewer in a severe disease model. Here, a SARS-CoV-2 DNA targeting the spike protein and delivered by jet injection, nCoV-S(JET), elicited neutralizing antibodies in hamsters and was protective in both wild-type and transiently immunosuppressed hamster models. This study highlights the DNA vaccine, nCoV-S(JET), we developed has a great potential to move to next stage of preclinical studies, and it also demonstrates that the transiently-immunosuppressed Syrian hamsters, which recapitulate severe and prolonged COVID-19 disease, can be used for preclinical evaluation of the protective efficacy of spike-based COVID-19 vaccines.
