    • This application relates to improved Group B Streptococcus ("GBS") saccharide-based vaccines comprising combinations of GBS polysaccharides with polypeptide antigens, and vice versa, such that the polypeptide and the saccharide each contribute to the immunological response in a recipient. The combination is particularly advantageous where the saccharide and polypeptide are from different GBS serotypes. The combined antigens may be present as a simple combination where separate saccharide and polypeptide antigens are administered together, or they may be present as a conjugated combination, where the saccharide and polypeptide antigens are covalently linked to each other. Preferably, the immunogenic compositions of the invention comprise a GBS saccharide antigen and at least two GBS polypeptide antigens, wherein said GBS saccharide antigen comprises a saccharide selected form GBS serotype Ia, Ib, and III, and wherein said GBS polypeptide antigens comprise a combination of at least two polypeptide or fragments thereof selected from the antigen group consisting of GBS 80, GBS 91, GBS 104, GBS 147, GBS 173, GBS 276, GBS 305, GBS 313, GBS 322, GBS 328, GBS 330, GBS 338, GBS 358, GBS 361, GBS 404, GBS 656, GBS 690, and GBS 691.
    • 本申请涉及包含GBS多糖与多肽抗原的组合的改进的B组链球菌(“GBS”)糖基疫苗,反之亦然,使得多肽和糖各自对接受者的免疫应答有贡献。 当糖和多肽来自不同的GBS血清型时,该组合是特别有利的。 组合的抗原可以作为单独的组合存在,其中单独的糖和多肽抗原一起施用,或者它们可以作为共轭组合存在,其中糖和多肽抗原彼此共价连接。 优选地,本发明的免疫原性组合物包含GBS糖抗原和至少两种GBS多肽抗原,其中所述GBS糖抗原包含选自GBS血清型Ia,Ib和III的糖,并且其中所述GBS多肽抗原包含 至少两种选自GBS 80,GBS 91,GBS 104,GBS 147,GBS 173,GBS 276,GBS 305,GBS 313,GBS 322,GBS 328,GBS 330,GBS 338, GBS 358,GBS 361,GBS 404,GBS 656,GBS 690和GBS 691。
