    • Chimeric parainfluenza viruses (PIVs) are provided that incorporate a PIV vector genome or antigenome modified to encode a chimeric glycoprotein incorporating one or more heterologous antigenic domains, fragments, or epitopes of a second, antigenically distinct HPIV. These chimeric viruses are infectious and attenuated in humans and other mammals and are useful in vaccine formulations for eliciting an immune responses against one or more PIVs, and, optionally against respiratory syncytial virus (RSV). Also provided are isolated polynucleotide molecules and vectors incorporating a chimeric PIV genome or antigenome which includes a HPIV vector genome or antigenome combined or integrated with one or more heterologous genome segment(s) encoding one or more antigenic determinant(s) of a heterologous PIV to encode a chimeric glycoprotein. In preferred aspects of the invention, the chimeric virus is attenuated for use as a vaccine agent by additional mutations or nucleotide modifications introduced into the chimeric genome or antigenome.
    • 提供了嵌合副流感病毒(PIV),其包含PIV载体基因组或经修饰的反义基因组,以编码掺入一个或多个异源抗原结构域,片段或第二抗原性不同HPIV表位的嵌合糖蛋白。 这些嵌合病毒在人和其他哺乳动物中是感染性和减毒性的,并且可用于引发针对一种或多种PIV的免疫应答的疫苗制剂,以及任选地抗呼吸道合胞病毒(RSV)。 还提供了分离的多核苷酸分子和掺入嵌合PIV基因组或反基因组的载体,其包括与编码异源PIV的一个或多个抗原决定簇的一个或多个异源基因组片段组合或整合的HPIV载体基因组或抗原子集, 编码嵌合糖蛋白。 在本发明的优选方面,嵌合病毒通过引入到嵌合基因组或反基因组中的附加突变或核苷酸修饰来减毒用作疫苗剂。
