  • Patent number: 8673318
    Abstract: The present invention relates to a method for the cultivation of primary cells. The primary cells are cultivated in a serum free medium comprising a factor selected from the group consisting of growth factors and attachment factors. The method for the cultivation of primary cells may be one step in a method for the amplification of viruses, such as poxviruses. According to this latter method the primary cells are cultivated in a serum free medium comprising a factor selected from the group consisting of growth factors and attachment factors. The cells are then infected with the virus and the infected cells are cultivated in serum free medium until progeny virus is produced.

  • Patent number: 8470598
    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.

  • Patent number: 7056723
    Abstract: The present invention relates to a method for the recovery of poxviruses, in particular modified Vaccinia virus Ankara (MVA), from infected cells. According to the present invention the virus-infected cells are subjected to a high-pressure homogenization to obtain a virus containing homogenate. The virus containing homogenate can be subjected to at least one purification step to obtain apoxvirus-enriched fraction. The invention further relates to the virus containing fraction and the virus containing homogenate obtained by the method according to the present invention.
