如果没有通过疫苗接种或自然感染获得足够的群体免疫力,2019年冠状病毒病大流行不太可能得到控制。目前批准的疫苗的免疫力下降表明,需要对诱导长期反应的疫苗进行评价。在这里,我们报告了我们的佐剂单剂量狂犬病病毒载体SARS-CoV-2 S1疫苗,CORAVAX,在仓鼠的免疫原性和有效性。CORAVAX诱导高SARS-CoV-2 S1特异性和病毒中和抗体(VNA),可预防仓鼠体重减轻、病毒载量、疾病、肺部炎症和细胞因子风暴。我们还观察到高狂犬病VNA滴度。综上所述,CORAVAX是一种有前途的双抗原疫苗候选者,可用于针对SARS-CoV-2和狂犬病病毒的临床评价。
Without sufficient herd immunity through either vaccination or natural infection, the coronavirus disease 2019 pandemic is unlikely to be controlled. Waning immunity with the currently approved vaccines suggests the need to evaluate vaccines causing the induction of long-term responses. Here, we report the immunogenicity and efficacy of our adjuvanted single-dose Rabies-vectored SARS-CoV-2 S1 vaccine, CORAVAX, in hamsters. CORAVAX induces high SARS-CoV-2 S1-specific and virus-neutralizing antibodies (VNAs) that prevent weight loss, viral loads, disease, lung inflammation, and the cytokine storm in hamsters. We also observed high Rabies VNA titers. In summary, CORAVAX is a promising dual-antigen vaccine candidate for clinical evaluation against SARS-CoV-2 and Rabies virus.
