    • The present invention relates to a combination of a priming composition and a boosting composition to prime and boost an immune response in a subject whereby the immune response resulting from administration of the priming composition to the subject is capable of being boosted. The priming composition comprises a DNA plasmid that comprises a nucleic acid molecule encoding an influenza virus hemagglutinin (HA) or an epitope-bearing domain thereof. The boosting composition comprises an influenza vaccine. The present invention also relates to a method to use such a combination to vaccinate a subject and to enhance an immune response to an influenza vaccine administered alone. Such a combination can elicit an immune response not only against at least one influenza virus strain from which the priming composition or boosting composition is derived but also to at least one heterologous influenza virus strain.
    • 本发明涉及引发组合物和促进组合物的组合以引发和增强受试者中的免疫应答,由此将引发组合物施用于受试者的免疫应答能够被增强。 引发组合物包含DNA质粒,其包含编码流感病毒血凝素(HA)或其表位承载结构域的核酸分子。 助推组合物包含流感疫苗。 本发明还涉及使用这种组合来接种受试者并增强对单独施用的流感疫苗的免疫应答的方法。 这种组合可以引起免疫应答,不仅针对起源组合物或促进组合物得自其中的至少一种流感病毒株,而且还可引发至少一种异源流感病毒株。
