Abstract: Compositions and methods are described for generating an improved effective immune response against an immunogen in humans. The enhanced immune response, is obtained by using an MVA vector as a prime and an adenovirus vector as a boost and is characterized by a high level of antibody response specific to the immunogen, and an enhanced cellular immune response. The compositions and methods can be used to provide a protective immunity against a disease, such as an infection of one or more subtypes of Ebola and Marburg filoviruses, in humans.

Abstract: The invention relates to vectors comprising two or more homologous nucleotide sequences and methods for generating them. The invention concerns substituting bases in the homologous nucleotide sequences with different bases that do not alter the encoded amino acid sequence. The invention allows for the reduction of intramolecular recombination between homologous nucleotide sequences, in particular in mammalian cells. The invention further relates to nucleotide sequences containing substituted bases.
Abstract: The present invention relates to recombinant modified vaccinia virus Ankara (MVA) and to methods of using the same. In particular, the invention relates to recombinant MVA comprising a nucleotide sequence encoding for a structural protein of an equine encephalitis virus (EEV) excluding encoding for a capsid protein of the EEV, a composition in particular a pharmaceutical composition, a vaccine or kit comprising the recombinant MVA, uses and methods thereof e.g., suitable for treating and/or preventing a western, Venezuelan, and/or eastern equine encephalitis virus caused disease.

Abstract: The invention is drawn to compositions and methods for the induction of an immune response, in particular a strong CD8 T cell response, to a specific antigenic determinant without raising a significant antibody response to the antigenic determinant after a first, priming immunization. The method comprises administering to the host a recombinant poxviral vector comprising a transcriptional control element comprising an early and/or late element linked to a nucleotide sequence encoding the antigenic determinant. The recombinant poxviral vector comprises a transcriptional control element comprising an early and/or late element linked to a nucleotide sequence encoding the antigenic determinant. The late element may be stronger than the cowpox ATI promoter in HeLa cells.
