    • The present invention provides an attenuated virus, which is derived from Modified Vaccinia Ankara virus and characterized by induction of protective immunity against a lethal vaccinia virus infection in a mouse, whereby the effective amount of the MVA-BN virus, or a derivative thereof, required to confer said immunity is less than the effective amount of MVA-575 required to render said mouse immune to a lethal vaccinia virus infection, and/or the MVA-BN virus, or a derivative thereof, induces at least substantially the same level of immunity in vaccinia virus prime/vaccina virus boost regimes when compared to DNA prime/vaccinia virus boost regimes. It further describes recombinant viruses derived from this virus and the use of the virus, or its recombinants, as a medicament or vaccine. A method is provided for inducing an immune response in individuals who may be immune-compromised, receiving antiviral therapy, or have a pre-existing immunity to the vaccine virus.
    • 本发明提供一种减毒病毒,其来源于改良牛痘安卡拉病毒,其特征在于在小鼠中诱导针对致死性痘苗病毒感染的保护性免疫力,由此需要有效量的MVA-BN病毒或其衍生物 赋予所述免疫力小于使所述小鼠免疫致死性痘苗病毒感染所需的MVA-575的有效量,和/或MVA-BN病毒或其衍生物诱导至少基本上相同的免疫水平 与DNA痘苗/痘苗病毒增强方案相比,在痘苗病毒原始/疫苗病毒增强方案中。 它还描述了源自该病毒的重组病毒和病毒或其重组体作为药物或疫苗的用途。 提供了一种方法,用于在可能被免疫损害的个体中诱导免疫应答,接受抗病毒治疗或具有疫苗病毒的预先存在的免疫。
