Abstract: The invention relates to vaccines comprising recombinant vectors, such as recombinant adenoviruses. The vectors comprise heterologous nucleic acids encoding for at least two antigens from one or more tuberculosis-causing bacilli. Also described is the use of specific protease recognition sites linking antigens through which the encoded antigens are separated upon cleavage. After cleavage, the antigens contribute to the immune response in a separate manner. The recombinant vectors may comprise a nucleic acid encoding the protease cleaving the linkers and separating the antigens. Further described is the use of genetic adjuvants encoded by the recombinant vectors, wherein such genetic adjuvants may also be cleaved through the presence of the cleavable linkers and the specific protease.

Abstract: Provided is a process for the production of poliovirus, comprising the steps of: a) providing a serum-free suspension culture of cells, which are primary human retina (HER) cells that have been immortalized by expression of adenovirus E1 sequences, b) infecting the cells with poliovirus, at a cell density of between 2×106 cells/ml and 150×106 cells/ml, and c) harvesting poliovirus at a time of between 12 and 48 hours after infection.
Abstract: Described are binding molecules, such as human monoclonal antibodies, that bind to hemagglutinin of influenza B viruses, and have a broad neutralizing activity against such influenza viruses. These binding molecules do not bind to hemagglutinin of influenza A viruses. Further provided are nucleic acid molecules encoding the binding molecules, and compositions comprising the binding molecules. The binding molecules can be used in the diagnosis of, prophylaxis against, and/or treatment of influenza B virus infections.
Abstract: Described are methods for vaccinating a subject against influenza comprising administering a vaccine multiple times to a subject where the vaccine comprises influenza hemagglutinin (HA) and neuraminidase (NA) proteins from at least a first influenza strain, wherein the HA and NA proteins of the first influenza strain are administered to the subject at least three times within a period of less than one year. Such immunization schemes induce cross-protection against heterologous and heterosubtypic influenza strains.
