    • The invention includes a chimeric virus for use in a vaccine preparation having a genome comprising nucleic acid sequences encoding at least one structural protein from one flavivirus and nucleic acid sequences encoding nonstructural protein from another flavivirus. The genome preferably includes mutations within the viral genome that reduce virus virulence and in a particularly preferred embodiment these vaccines are directed to flaviviruses such as dengue virus, tick-borne encephalitis virus and Japanese encephalitis virus. The invention also includes a baculovirus having a recombinant dengue cDNA sequence which encodes: (1) dengue virus capsid protein, pre-matrix protein, envelope glycoprotein and NS1 and NS2a nonstructural proteins or (2) dengue envelope glycoprotein or (3) dengue non-structural proteins NS1 and NS2a. The invention further includes a baculovirus having a recombinant Japanese B encephalitis virus cDNA sequence which encodes the Japanese B encephalitis virus capsid protein, pre-matrix protein, envelope glycoprotein and non-structural proteins NS1 and NS2a. The invention further includes a vaccine and a method to produce that vaccine.
    • 本发明包括用于疫苗制剂的嵌合病毒,其具有包含编码来自一种黄病毒的至少一种结构蛋白的核酸序列的基因组和来自另一种黄病毒的编码非结构蛋白的核酸序列。 基因组优选包括在病毒基因组内的减少病毒毒力的突变,并且在特别优选的实施方案中,这些疫苗针对黄病毒例如登革热病毒,蜱传脑炎病毒和日本脑炎病毒。 本发明还包括具有重组登革热cDNA序列的杆状病毒,其编码:(1)登革热病毒衣壳蛋白,前基质蛋白,包膜糖蛋白和NS1和NS2a非结构蛋白或(2)登革热包膜糖蛋白或(3) 结构蛋白NS1和NS2a。 本发明还包括具有编码日本B型脑炎病毒衣壳蛋白,前基质蛋白,包膜糖蛋白和非结构蛋白NS1和NS2a的重组日本B脑炎病毒cDNA序列的杆状病毒。 本发明还包括疫苗和生产该疫苗的方法。
