    • Chimeric human-bovine respiratory syncytial virus (RSV) are infectious and attenuated in humans and other mammals and useful in vaccine formulations for eliciting an anti-RSV immune response. Also provided are isolated polynucleotide molecules and vectors incorporating a chimeric RSV genome or antigenome which includes a partial or complete human or bovine RSV "background" genome or antigenome combined or integrated with one or more heterologous gene(s) or genome segment(s) of a different RSV strain. Chimeric human-bovine RSV of the invention include a partial or complete "background" RSV genome or antigenome derived from or patterned after a human or bovine RSV strain or subgroup virus combined with one or more heterologous gene(s) or genome segment(s) of a different RSV strain or subgroup virus to form the human-bovine chimeric RSV genome or antigenome. In preferred aspects of the invention, chimeric RSV incorporate a partial or complete bovine RSV background genome or antigenome combined with one or more heterologous gene(s) or genome segment(s) from a human RSV. Genes of interest include any of the NS1, NS2, N, P, M, SH, M2(ORF1), M2(ORF2), L, F or G genes or a genome segment including a protein or portion thereof. A variety of additional mutations and nucleotide modifications are provided within the human-bovine chimeric RSV of the invention to yield desired phenotypic and structural effects.

    • Chimeric respiratory syncytial virus (RSV) and vaccine compositions thereof are produced by introducing one or more heterologous gene(s) or gene segment(s) from one RSV subgroup or strain into a recipient RSV background of a different subgroup or strain. The resulting chimeric RSV virus or subviral particle is infectious and attenuated, preferably by introduction of selected mutations specifying attenuated phenotypes into a chimeric genome or antigenome to yield, for example, temperature sensitive (ts) and/or cold adapted (ca) vaccine strains. Alternatively, chimeric RSV and vaccine compositions thereof incorporate other mutations specifying desired structural and/or phenotypic characteristics in an infectious chimeric RSV. Such chimeric RSV incorporate desired mutations specified by insertion, deletion, substitution or rearrangement of one or more selected nucleotide sequence(s), gene(s), or gene segment(s) in a chimeric RSV clone. This provides a method for development of novel vaccines against diverse RSV strains by using a common attenuated backbone as a vector to express protective antigens of heterologous strains. The immune system of an individual is stimulated to induce protection against natural RSV infection, preferably in a multivalent manner to achieve protection against multiple RSV strains and/or subgroups.
    • 嵌合呼吸道合胞病毒(RSV)及其疫苗组合物通过将一个或多个异源基因或基因区段从一个RSV亚组或菌株引入到不同亚组或菌株的受体RSV背景中来产生。 所得到的嵌合RSV病毒或亚病毒颗粒是感染性和减毒性的,优选通过将指定减毒表型的选定突变引入到嵌合基因组或反基因组中以得到例如温度敏感(ts)和/或冷适应(ca)疫苗株。 或者,嵌合RSV及其疫苗组合物掺入在感染性嵌合RSV中指定所需结构和/或表型特征的其它突变。 这种嵌合RSV包含通过嵌合RSV克隆中的一个或多个选定的核苷酸序列,基因或基因片段的插入,缺失,取代或重排而指定的所需突变。 这提供了通过使用共同的减毒骨架作为表达异源株的保护性抗原的载体来开发针对不同RSV菌株的新型疫苗的方法。 刺激个体的免疫系统以诱导针对天然RSV感染的保护,优选以多价方式实现针对多个RSV菌株和/或亚组的保护。
