The present invention concerns methods and compositions for the treatment of cancer and cancer cells using intravascular administration of a vaccinia virus. In some embodiments, methods and compositions involve a replicative vaccinia virus that encodes GM-CSF.

The compositions and methods are described for generating an immune response to a flavivirus such as Zika virus. The compositions and methods described herein relate to a modified vaccinia Ankara (MVA) vector encoding one or more viral antigens for generating a protective immune response to a member of genus Flavivirus (such as a member of species Zika virus), in the subject to which the vector is administered. The compositions and methods of the present invention are useful both prophylactically and therapeutically and may be used to prevent and/or treat an infection caused by Flavivirus.

This invention provides vaccines for inducing an immune response and protection against filovirus infection for use as a preventative vaccine in humans. In particular, the invention provides chimpanzee adenoviral vectors expressing filovirus proteins from different strains of Ebolavirus (EBOV) or Marburg virus (MARV).

The object of the present invention is to provide a test method using a novel administration method of an extract from inflamed tissues inoculated with vaccinia virus or a preparation containing the extract. It has been demonstrated that by sustainedly administering an extract from inflamed tissues inoculated with vaccinia virus or a preparation containing the extract by using a continuous administration device according to the present invention, a comparable effect is exerted at a very low dose compared with conventional administration methods such as oral administration. Therefore, the present invention can provide a test method using animals requiring less burden on a researcher, a treatment of patient at a low dose, and the like.

The invention relates in various aspects to stem cells comprising a synthetic chimeric poxvirus (scPV), which can be used for the treatment of cancer or other infectious diseases. It also relates to methods for delivering the scPV comprising infecting the stem cells with the scPV and administering the infected stem cells to a subject.

The compositions and methods described herein relate to a modified vaccinia Ankara (MVA) vector encoding one or more viral antigens for generating a protective immune response to a member of genus Flavivirus (such as a member of species Zika virus), in the subject to which the vector is administered. The compositions and methods of the present invention are useful both prophylactically and therapeutically and may be used to prevent and/or treat an infection caused by Flavivirus.

A recombinant oncolytic virus with improved safety and anticancer effect and a use thereof are disclosed. The recombinant oncolytic virus is obtained by inserting an HSV-TK fragment-encoding gene into a TK gene region to delete TK of Vaccinia virus. The oncolytic virus expresses an HSV-TK fragment to phosphorylate GCV so that cancer cells infected with the oncolytic virus and their neighboring cancer cells can be killed. GCV is also involved in the suppression of viral proliferation and thus can control side effects caused by a virus even upon the administration of a high dose of the virus.

The pesent invention relates to new insertion sites useful for the integration exogenous sequence into an intergenic region (IGR) of a vaccinia virus genome, where the IGR is located between or is flanked by two adjacent open reading frames (ORFs) of the vaccinia virus genome, and wherein the ORFs correspond to conserved genes, and to related plasmid vectors useful to insert exogenous DNA into the genome of a vaccinia virus, and further to recombinant vaccinia viruses comprising an exogenous sequence inserted into said new insertion site as a medicine or vaccine.
