针对登革病毒的疫苗组合物
摘要：
疫苗组合物，其包含至少一种基于登革病毒(DV)衣壳蛋白的抗原和标识为SEQ ID NO.1的寡核苷酸。包含由DV2的衣壳与相同血清型的包膜蛋白的结构域III形成的融合蛋白(添加有标识为SEQ ID NO.1的寡核苷酸)的疫苗组合物在小鼠中产生最高水平的细胞免疫应答和保护作用，相比于用添加有先前所报道的具有潜在辅佐能力的寡核苷酸的相同抗原的制剂所产生的那种而言。在非人灵长类中证明了包含SEQ ID NO.1所示寡核苷酸的组合物的效力。这些组合物可以是单价的、二价的和四价的，并且可以在各种不同的免疫接种制度中进行组合以用于诱导针对四种病毒血清型的功能性免疫应答。
摘要（英）：

Vaccine compositions that comprise at least one antigen based on the dengue virus (DV) capsid protein and the oligonucleotide identified as SEQ ID NO 1. The vaccine composition that comprises a fusion protein formed by the DV2 capsid and domain III of the envelope protein of the same serotype, together with the oligonucleotide identified as SEQ ID NO 1, gives rise to higher levels of cellular immune response and protection in mice as compared with that produced by formulations of the same antigen together with oligonucleotides with potential adjuvant capacity which were reported previously. The efficacy of the compositions that comprise the SEQ ID NO 1 oligonucleotide has been demonstrated in non-human primates. These compositions may be monovalent, bivalent or tetravalent and are combined in different immunization regimes with a view to inducing a functional immune response to the four viral serotypes.
