Abstract: Provided herein are recombinant modified vaccinia virus Ankara (MVA) strains as improved vaccines against infection with Respiratory Syncytial Virus (RSV virus) and to related products, methods and uses. Specifically, provided herein are genetically engineered recombinant MVA vectors comprising at least one nucleotide sequence encoding an antigenic determinant of an RSV membrane glycoprotein and at least one nucleotide sequence encoding an antigenic determinant of an RSV nucleocapsid protein. Also provided herein are products, methods and uses thereof, e.g., suitable to affect an immune response in a subject, or suitable to diagnose an RSV infection, as well as to determine whether a subject is at risk of recurrent RSV infection.

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 invention concerns a recombinant modified vaccinia virus Ankara (MVA virus) expressing at least two external influenza virus antigens and/or an epitope of one or more of the at least two antigens and at least two internal influenza virus antigens and/or an epitope of the at least two antigens. The invention, thus, concerns a recombinant MVA virus encoding multiple external and/or internal influenza virus antigens, preferably from multiple influenza virus strains. The invention further concerns the use of said recombinant MVA in preparing a medicament and vaccine for influenza virus. Further encompassed by the present invention are methods, composition and kits.

Abstract: The invention encompasses recombinant poxviruses, preferably modified Vaccinia Ankara (MVA) viruses, comprising a Pr13.5 promoter operably linked to a nucleotide sequence encoding an antigen and uses thereof. The invention is drawn to compositions and methods for the induction of strong CD8 T cell and antibody responses to a specific antigen(s) by administering one or more immunizations of the recombinant MVA to a mammal, preferably a human.

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.
