The recent outbreak of H7N9 influenza virus infections in humans in China has raised concerns about the pandemic potential of this strain. Here, we test the efficacy of H3 stalk-based chimeric hemagglutinin universal influenza virus vaccine constructs to protect against H7N9 challenge in mice. Chimeric hemagglutinin constructs protected from viral challenge in the context of different administration routes as well as with a generic oil-in-water adjuvant similar to formulations licensed for use in humans.
近期中国出现的人感染H7N9流感病毒疫情引发了对该毒株大流行潜力的担忧。在此,我们测试了基于H3茎部的嵌合血凝素通用流感病毒疫苗构建体在小鼠中抵御H7N9攻击的效力。嵌合血凝素构建体在不同给药途径以及与一种类似于已获许可用于人类的配方的通用水包油佐剂联合使用的情况下,均可保护小鼠免受病毒攻击。
