The invention is directed to a recombinant nucleic acid molecule comprising an expression cassette encoding a polyepitope comprising T-cell antigens from proteins of African Swine Fever Virus. The invention further relates to a viral particle, comprising said recombinant nucleic acid molecule, and to a viral particle comprising B-cell antigens of African Swine Fever Virus. The invention further relates to methods of stimulating an immune response in a pig comprising administering the recombinant molecule of the invention, and/or the viral particle of the invention, to the pig in an amount effective to induce an immune response.

African swine fever virus vaccine

The invention relates to the process for generating infectious Newcastle disease virus (NDV) entirely from cloned full-length cDNA and to the use of vaccines and diagnostic assays generated with and derived from said process. The process offers the possibility to modify the NDV genome by means of genetic modification and allows the introduction of mutations, deletions and/or insertions. The process can be used to modify the virulence of NDV, thereby generating new attenuated live vaccines with enhanced properties. The process can be used to modify the antigenic make-up of NDV, thus allowing the generation of live NDV marker vaccines which can be serologically distinguished from NDV field strains.
