Abstract: The present invention relates to novel insertion sites useful for the integration of exogenous sequences into the Modified Vaccinia Ankara (MVA) virus genome. The present invention further provides plasmid vectors to insert exogenous DNA into the genome of MVA. Furthermore, the present invention provides recombinant MVA comprising an exogenous DNA sequence inserted into the new insertion site as medicine or vaccine.
Abstract: The present invention provides an attenuated virus, which is derived from Modified Vaccinia Ankara virus and characterized by the loss of its capability to reproductively replicate in human cell lines. 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. In addition, a method is provided for the administration of a therapeutically effective amount of the virus, or its recombinants, in a vaccinia virus prime/vaccinia virus boost innoculation regimen. The present invention relates to a method of virus amplification in primary cells which are cultivated in a serum free medium. Viruses produced by this method are advantageously free of any infectious agents comprised in animal sera.

Furthermore, the invention relates to an in vitro method for producing IFN-? and/or generating or obtaining a population of IFN-? producing CD8+ or eCD8+ cDCs as well as in vitro method for detecting or screening for CD8+ and/or eCD8+ cDCs. In addition, the invention relates to a Flt3-ligand or a M-CSF receptor ligand for use in increasing the level of CD8+ and/or eCD8+ cDCs in a subject suffering from an infectious disease or cancer.
Abstract: The present invention provides an attenuated virus, which is derived from Modified Vaccinia Ankara virus, wherein 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.
