寨卡病毒 (ZIKV) 在全球的传播及其与先天性缺陷的意外关联,需要快速开发安全有效的疫苗。在这里,我们报告了一种重组嵌合 ZIKV 候选疫苗(称为 ChinZIKV)的开发和表征,该候选疫苗使用获得许可的日本脑炎减毒活疫苗 SA14-14-2 作为遗传骨架来表达 ZIKV 的 prM-E 蛋白。 ChinZIKV 在体外保留其复制活性和遗传稳定性,同时在多种动物模型中表现出减毒表型。值得注意的是,用单剂 ChinZIKV 对小鼠和恒河猴进行免疫可引发强烈且持久的免疫反应,并提供针对 ZIKV 攻击的完全保护。值得注意的是,用 ChinZIKV 免疫的雌性小鼠在怀孕期间受到 ZIKV 攻击时可以免受胎盘和胎儿损伤。总体而言,我们的研究为应对 ZIKV 紧急情况提供了替代疫苗平台,并且 ChinZIKV 的安全性、免疫原性和保护特性值得进一步的临床开发。
The global spread of Zika virus (ZIKV) and its unexpected association with congenital defects necessitates the rapid development of a safe and effective vaccine. Here we report the development and characterization of a recombinant chimeric ZIKV vaccine candidate (termed ChinZIKV) that expresses the prM-E proteins of ZIKV using the licensed Japanese encephalitis live-attenuated vaccine SA14-14-2 as the genetic backbone. ChinZIKV retains its replication activity and genetic stability in vitro, while exhibiting an attenuation phenotype in multiple animal models. Remarkably, immunization of mice and rhesus macaques with a single dose of ChinZIKV elicits robust and long-lasting immune responses, and confers complete protection against ZIKV challenge. Significantly, female mice immunized with ChinZIKV are protected against placental and fetal damage upon ZIKV challenge during pregnancy. Overall, our study provides an alternative vaccine platform in response to the ZIKV emergency, and the safety, immunogenicity, and protection profiles of ChinZIKV warrant further clinical development.
