The disclosure provides recombinant vesicular stomatitis vims (VSV) particles, wherein the VSV glycoprotein (G) is replaced by a coronavirus spike (S) glycoprotein, or a fragment or a derivative thereof, as well as compositions, vaccines, kits, and methods for using the recombinant VSV particles. In a specific embodiment, the S glycoprotein is derived from Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) and the methods are for the treatment or prevention of a disease or disorder in a subject infected with SARS-CoV-2. In certain embodiments, the disease or disorder is COVID-19.

A recombinant vesicular stomatitis vims (rVSV) carrying at least one gene that encodes for a MERS-CoV structural protein or modifications thereof. Vaccines or immunogenic compositions against MERS-CoV, and prime boost immunization platforms a prime boost immunization combination against MERS-CoV including: (a) a prime vaccine or immunogenic composition comprising a rVSV carrying at least one gene that encodes for a MERS-CoV structural protein or modifications thereof, and (b) a boost vaccine or immunogenic composition comprising a rVSV carrying the same at least one gene that encodes for a MERS-CoV structural protein or modifications thereof. The at least one gene can be genetically modified to encode a modified MERS-CoV structural protein that elevates glycoprotein synthesis and trigger efficient humoral immune response.

The present application relates to a medicine for treating tumors. A novel attenuated oncolytic virus strain is provided by means of a site-directed mutation of a wild-type virus matrix protein M of a vesicular stomatitis virus. On the basis of the attenuated oncolytic virus strain, an oncolytic virus vaccine is provided by inserting an exogenous gene into the attenuated strain. A medicine capable of treating multiple types of tumors is provided by the use of the oncolytic virus vaccine in combination with the immune checkpoint inhibitor.

The present invention relates to recombinant measles virus expressing proteins of a Plasmodium parasite and their applications, in particular in inducing preventive protection against a Plasmodium infection. The present invention is directed to recombinant measles virus (MV) expressing (i) at least the circumsporozoite (CS) protein of a Plasmodium parasite or an antigenic fragment thereof, and at least a chimeric antigen of a Plasmodium parasite as defined below, or (ii) at least the CS protein of a Plasmodium parasite or an antigenic fragment thereof, at least a chimeric antigen of a Plasmodium parasite as defined below and at least the reticulocyte-binding protein homologue 5 (RH5) of a Plasmodium parasite or an antigenic fragment thereof, and concerns recombinant infectious virus partides of said MV-malaria able to replicate in a host after an administration. The present invention provides means, in particular nucleic acids, vectors, cells and rescue systems to produce these recombinant infectious virus particles. The present invention also relates to the use of these recombinant infectious virus particles, in particular under the form of a composition, more particularly in a vaccine composition, for the prevention of a Plasmodium infection or for the preventive protection against clinical outcomes of infection by a Plasmodium parasite.

The disclosure provides methods for determining the presence of coronavirus neutralizing antibodies in a sample as well as associated compositions and kits. The methods of the disclosure use recombinant vesicular stomatitis virus (VSV) particles, wherein the VSV glycoprotein (G) is replaced by a coronavirus spike (S) glycoprotein or a fragment or a derivative thereof. In a specific embodiment, the S glycoprotein is derived from Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) and the methods are used for determining the presence of SARS-CoV-2 neutralizing antibodies.

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.

A vaccination method is provided. The method comprises administering to a mammal a histone deacytelase inhibitor in conjunction with a vaccine that expresses an antigen to which the mammal has a pre-existing immunity.

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

Provided herein is a method for inducing an immune response to at least one neoantigen, the method comprising administering to a subject a priming composition comprising a peptide antigen conjugate and at least a first boost. The first boost comprises a first oncolytic virus comprising a genome that expresses a first peptide or a second peptide, wherein the first and second peptide are each capable of inducing an immune response to at least one neoantigen. The method further comprises administering the subject a second boost, comprising a second oncolytic virus comprising a genome that expresses a third peptide or a fourth peptide, wherein the third peptide and the fourth peptide are each capable of inducing an immune response to at least one neoantigen, and wherein the second oncolytic virus is immunologically distinct from the first oncolytic virus. The subject may have pre-existing immunity to the at least one neoantigen.

The present relation relates to a transgenic Vero cell line expressing CD4 and CCR5. The present invention encompasses the preparation and purification of immunogenic compositions which are formulated into the vaccines of the present invention.
