  • Patent number: 9623098
    Abstract: The present invention relates to combined vaccines against measles and human papilloma virus (HPV). In particular, the invention relates to recombinant measles virus vectors containing heterologous nucleic acid encoding single or several antigens derived from HPV, preferably, the major capside antigen L1, the minor capside antigen L2, the early gene E6 and the early gene E7 oncoproteins of HPV type 16, and optionally of types 18, 6 and 11. In a first embodiment, prophylactic vaccines are generated expressing HPV antigens, preferably L1 and/or L2 such that they induce a potent long-lasting immune response in mammals, preferably humans, to protect against HPV and MV infection. In another embodiment, therapeutic vaccines are generated expressing E6 and E7 proteins, and optionally L1 and L2, such that they induced strong immune responses will resolve persistent HPV infections at early or late stages, including HPV-induced cervical carcinoma.

  • Patent number: 9308250
    Abstract: A combined measles-malaria vaccine containing different attenuated recombinant measles-malaria vectors comprising a heterologous nucleic acid encoding several Plasmodium falciparum antigens is described. Preferably, it relates to viral vectors that comprise nucleic acids encoding the circumsporozoite (CS) protein of P. falciparum, the merozoite surface protein 1 (MSP-1) of P. falciparum, and its derivatives (p-42; p-83-30-38) in its glycosylated and secreted forms, and apical membrane antigen1 (AMA1) of P. falciparum, in its anchored or secreted form. The viral vector stems from an attenuated measles virus, based on a strain that is used as a vaccine and is efficient in delivering the gene of interest and that binds to and infects the relevant immune cells efficiently.

  • Patent number: 8158416
    Abstract: The present invention relates, in general, to a methodology for the generation of nonsegmented negative-strand RNA viruses (Pringle, 1991) from cloned deoxyribonucleic acid (cDNA). Such rescued viruses are suitable for use as vaccines, or alternatively, as plasmids in somatic gene therapy applications. The invention also relates to cDNA molecules suitable as tools in this methodology and to helper cell lines allowing the direct rescue of such viruses. Measles virus (MV) is used as a mode for other representatives of the Mononegavirales, in particular the family Paramyxoviridae.
