Cancer is treated via a coordinated treatment regimen that use various compounds and compositions that employ a combination vaccination together with immune modulatory treatment and biasing of an immune response towards a Th1 profile.

Disclosed are synthetic MVA-based vaccines for preventing or treating infections caused by a coronavirus or variants thereof.

Disclosed herein are self-replicating RNA molecules encoding prostate neoantigens, vaccines, and method of treating and preventing prostate cancer using the self-replicating RNA molecules and vaccines.

The invention relates to the field of immunity against Coronaviruses. In this respect, the invention provides vectorized antigens derived from Coronaviruses that trigger an immune response against Coronaviruses. The invention accordingly relates to an active ingredient which is a live attenuated recombinant measles virus expressing Coronavirus antigen(s) and to its use in eliciting immunity, in particular protective immunity against SARS-CoV-2 strain and advantageously broad-spectrum protective immunity against various strains of Coronaviruses.

The present invention is directed to an artificial nucleic acid and to polypeptides suitable for use in treatment or prophylaxis of an infection with Henipavirus, particularly Hendra virus and/or Nipah virus or a disorder related to such an infection. In particular, the present invention concerns a Hendra virus and/or Nipah virus vaccine. The present invention is directed to an artificial nucleic acid, polypeptides, compositions and vaccines comprising the artificial nucleic acid or the polypeptides. The invention further concerns a method of treating or preventing a disorder or a disease, first and second medical uses of the artificial nucleic acid, polypeptides, compositions and vaccines. Further, the invention is directed to a kit, particularly to a kit of parts, comprising the artificial nucleic acid, polypeptides, compositions and vaccines.

The present disclosure provides a nanoparticle comprising a positively-charged surface and an interior comprising (i) a core and (ii) at least two nucleic acid layers, wherein each nucleic acid layer is positioned between a cationic lipid bilayer, wherein the nanoparticle comprises RNA molecules encoding a SARS-CoV-2 protein. Methods of making such nanoparticles are further provided herein. Additionally, related cells, populations of cells, pharmaceutical compositions comprising the presently disclosed nanoparticles are provided. Methods of increasing an immune response against a tumor in a subject, methods of delivering RNA molecules to an intra-tumoral microenvironment, lymph node, and/or a reticuloendothelial organ in a subject, and methods of treating a subject with a disease are furthermore provided.

A vaccine for preventing CoV infection includes at least one DNA, RNA or protein sequence for S protein with at least one modification which is a full deletion or partial deletion of the SI region or a partial or full replacement of the SI region. A method of vaccinating a mammal subject against infection from at least one group of CoV includes separating a broad group of CoV into homology groups, creating a modified S protein containing at least one modification at its S1 region, and identifying at least one consensus sequence for each homology group which has a sequence identity of greater than 60% to all other members of the homology group. The consensus sequence is a protein sequence for the modified S protein, a DNA sequence encoding the modified S protein, and an RNA sequence encoding the modified S protein.

An active or inactivated recombinant vaccine against COVID-19 is described that comprises a Newcastle disease viral vector and a pharmaceutically acceptable carrier, adjuvant and/or excipient, characterized in that the viral vector is a virus capable of generating a cellular immune response that has a SARS-CoV-2 exogenous nucleotide sequence inserted,

The present invention is in the field of immunotherapy, in particular tumor immunotherapy. The present invention provides pharmaceutical formulations for delivering RNA to antigen presenting cells such as dendrite cells (DCs) in the spleen after systemic administration. In particular, the formulations described herein enable to induce an immune response after systemic administration of antigen-coding RNA.

The present disclosure provides compositions and methods for the generation of an antibody or immunogenic composition, such as a vaccine, through epitope focusing by variable effective antigen surface concentration. Generally, the composition and methods of the disclosure comprise three steps: a “design process” comprising one or more in silico bioinformatics steps to select and generate a library of potential antigens for use in the immunogenic composition; a “formulation process”, comprising in vitro testing of potential antigens, using various biochemical assays, and further combining two or more antigens to generate one or more immunogenic compositions; and an “administering” step, whereby the immunogenic composition is administered to a host animal, immune cell, subject or patient. Further steps may also be included, such as the isolation and production of antibodies raised by host immune response to the immunogenic composition.
