The present invention relates to compositions comprising a recombinant respiratory syncitial virus (RSV) Fusion (F) polypeptide that is stabilized in the pre-fusion conformation, wherein said RSV F polypeptide comprises at least one mutation as compared to a wild type RSV F polypeptide, wherein the at least one mutation is selected from the group consisting of: a) a mutation of the amino acid aspartic acid (D) on position 486, b) a mutation of the amino acid aspartic acid (D) on position 489, and c) a mutation of the amino acid serine (S) on position 398 and/or the amino acid lysine (K) on position 394. The invention also relate to compositions comprising an isolated nucleic acid molecule encoding said stable RSV F polypeptides. 本发明涉及组合物，这些组合物包含稳定化在该融合前构象的重组呼吸道合胞病毒(RSV)融合(F)多肽，其中如与野生型RSV F多肽相比，所述RSV F多肽包含至少个突变，其中该至少个突变选自下组，该组由以下各项组成：a)在位置486上的氨基酸天冬氨酸(D)的突变，b)在位置489上的氨基酸天冬氨酸(D)的突变，以及c)在位置398上的氨基酸丝氨酸(S)的突变和/或在位置394上的氨基酸赖氨酸(K)的突变。本发明还涉及包含编码所述稳定的RSV F多肽的分离的核酸分子的组合物。
