Disclosed are synthetic nanocarrier compositions with coupled adjuvant compositions as well as related methods.

The present invention relates to immunogenic compositions and methods for producing them, and in particular, immunogenic compositions comprising a protein antigen cross linked to an oxoadenine adjuvant.

Compositions comprising an antigen, a carbohydrate, and a metabolizable oil, methods of administering such compositions to a subject, methods of making such compounds, and related compositions, methods, and uses.

The present invention relates to a therapeutic peptide T specific immune therapy for use in the treatment of a cancer of an HLA-A2 (Human Leukocyte Antigen A2) positive patient, said treatment comprises a priming period consisting in two to three administrations of said therapeutic peptide T specific immune therapy, thereby inducing a memory T cell response.

Embodiments of a novel platform for delivering a peptide antigen to a subject to induce an immune response to the peptide antigen are provided. For example, nanoparticle polyplexes are provided that comprise a polymer linked to a peptide conjugate by an electrostatic interaction. The conjugate comprises a peptide antigen linked to a peptide tag through an optional linker. An adjuvant may be included in the nanoparticle polyplex, linked to either the polymer or the conjugate, or admixed with the nanoparticles. The nanoparticle polyplex can be administered to a subject to induce an immune response to the peptide antigen.

This invention reveals the pharmaceutical composition that includes the surface antigen (HBsAg) of the hepatitis B virus (HBV) and the antigen of the nucleocapsid (or core, HBcAg) of the same virus. The HBcAg of this composition contains messenger ribonucleic acid (mRNA) at a proportion of over 45% of the total amount of ribonucleic acid (RNA) in this antigen. Because of the changes in the constitution of the antigens forming it, the composition of the invention is useful for the prevention or treatment of chronic hepatitis B. It also covers the use of this pharmaceutical composition in the production of a drug for immuno-prophylaxis or immunotherapy against HBV infection, and its use to increase the immune response against an additional antigen that is co-administered with the mixture of these antigens.

An immunogenic composition for reducing the incidence or severity of subclinical and clinical signs of orthoreovirus infection is provided. The composition(s) includes at least one segment or portion thereof of orthoreovirus that is derived from a different serotype, host, or strain than at least one other segment or portion thereof. The present disclosure also provides methods for treating, preventing, and reducing the subclinical and clinical signs of orthoreovirus infection in a subject or group of subjects.

Chemical compositions and/or mixtures that allow nucleic acid to remain stable at ambient temperatures. The disclosed technology includes a solution and manufacturing methods thereof. The solution includes a chelating agent, a buffering agent, and a salt. The solution is configured to protect RNA and/or an RNA-based vaccine added to the solution and prevents or reduces degradation of the RNA and/or the RNA-based vaccine for a duration of 2 to 180 days over a temperature range of −20 degrees C. to +38 degrees C. The chelating agent can comprise ethylenediaminetetraacetic acid (EDTA). The buffering agent can comprise tris(hydroxymethyl)aminomethane (TRIS). The salt can comprise NaCl. The solution is configured to preserve an injectable mRNA vaccine added to the solution, and the solution is safe for injection into mammals.

The present invention describes immunogenic compositions containing immunogenic polypeptides of African Swine Fever (ASF) virus, including immunogenic compositions containing antigens other than ASF viral antigens, including antigens that may be used in immunization against pathogens that cause diarrheal diseases. Methods of eliciting an immune response with the immunogenic compositions as disclosed and methods of treating an ASF infection are also described.

The instant technology generally relates to improved methods for producing antibodies, antibody libraries, hybridomas, hybridoma libraries, etc. For example, these methods increase the number of antigen-specific B cells produced, increase the number of hybridomas, and/or increase the number of monoclonal antibodies that can be made in a given production cycle.
