The disclosure provides viral vaccine compositions for use in treating COVID-19 in a subject to whom the compositions are administered, as well as to methods of making and using the compositions.

The present relation relates to recombinant vesicular stomatitis virus for use as prophylactic and therapeutic vaccines as well as the preparation and purification of immunogenic compositions which are formulated into the vaccines of the present invention.

The disclosure provides methods and materials for treating cancer. Specifically, the disclosure provides a chimeric vesiculovirus comprising: (a) a first genomic fragment of a first vesiculovirus species; and (b) a second genomic fragment of a second vesiculovirus species different from said first vesiculovirus species; wherein the vesiculovirus species comprising vesicular stomatitis viruses (VSVs) and morreton Virus (MorV). Further disclosed are methods of using chimeric vesiculoviruses as oncolytic agents for treating cancer.

The present invention pertains to the provision of a vaccine comprising a first component (K) and a second component (V), wherein the first component (K) comprises a complex in which a cell penetrating peptide, an antigenic domain and a TLR agonist are functionally linked and the second component (V) comprises an oncolytic recombinant vesicular stomatitis virus expressing an antigenic domain. The invention further pertains to the use of the inventive vaccine in the treatment of cancer. The invention also provides a recombinant vesicular stomatitis virus expressing an antigenic domain and its use in cancer vaccines.

A recombinant vesicular stomatitits virus (rVSV) having a Zika virus (ZIKV) envelope (E) gene, a prime boost immunization combination against ZIKV including: (a) a prime vaccine or immunogenic composition comprising a recombinant vesicular stomatitis virus (rVSV) carrying a ZIKV envelope (E) protein, and (b) a boost vaccine or immunogenic composition comprising a rVSV carrying the same ZIKV E protein. The ZIKV gene can be genetically modified to encode a modified ZIKV E protein that elevates glycoprotein synthesis and trigger efficient humoral immune response.

Embodiments of the invention include compositions and methods related to non-VSV rhabdoviruses and their use as anti-cancer therapeutics. Such rhabdoviruses possess tumor cell killing properties in vitro and in vivo.

The present invention relates to the field of oncolytic viruses and in particular to a recombinant rhabdovirus, such as vesicular stomatitis virus encoding in its genome for a CCL21 protein. The invention is further directed to the use of the recombinant virus in the treatment of cancer, and also to methods for producing such viruses.
