The present disclosure provides inter alia compositions that comprise therapeutic agents (e.g., live attenuated viral antigens, therapeutic proteins, etc.) and a lipid component. The lipid component may comprise or consist of different types of lipid or lipids as described herein. In some embodiments the therapeutic agents are thermolabile. The present disclosure also provides methods for preparing compositions, including the aforementioned compositions (e.g., melt methods and spray injection methods among others).

The present invention refers to pharmaceutical products comprising immunogenic compositions for modulating the immune system, which comprise a therapeutically effective amount of a Immunological Response Shifter (IRS) comprising two or more immunoactive antigenic agents presenting pathogen-associated molecular patterns (PAMPS) and/or danger associated molecular patterns (DAMPS) and/or Stress Response Signals (SRS), in association with an antibiotic and one or more physiologically acceptable carriers, excipients, diluents or solvents. IN other embodiments, the present invention refers to methods to treat severe bacterial infections, sepsis and modulating the immune system.

The present disclosure relates to field of lyophilized/freeze-dried viral combination composition/formulation and methods for manufacturing and obtaining the composition comprising at least three live attenuated virus selected from a group of Coronavirus, Measles virus and Rubella virus; and stabilizers comprising of at least one carbohydrate, at least one amino acid and at least one hydrolyzed protein. The said lyophilized/freeze-dried viral combination composition/formulation is a vaccine composition that preserves the desired characteristics of each virus, including stability and immunogenicity. The composition can be safely administered subcutaneously as a combination vaccine composition such that the immunogenicity of each of the measles, rubella and SARS-CoV-2 is not inferior to that observed for each of the three viruses when administered as individual vaccines and is found to be equivalent or improved as compared to immunogenicity of SARS-CoV-2 vaccine given intranasally. The purification process is devoid of chromatography steps.

Disclosed herein are isolated rubella viral vector constructs that include a rubella non-structural protein open reading frame (ORF) without an in-frame deletion, a rubella structural protein ORF, and a heterologous antigenic insert. In one example, the heterologous antigenic insert is positioned within the rubella structural protein ORF. In some examples, the heterologous antigenic insert is positioned in the rubella structural protein ORF in between a gene encoding structural protein E2 and a gene encoding structural protein E1. Exemplary antigenic inserts include HIV, SIV, RSV or hepatitis B surface antigens. In some examples, the HIV antigenic insert is a Gag antigenic insert, a gp41 antigenic insert or a gp120 antigenic insert. Also disclosed are uses of the isolated rubella viral vector, such as to induce an immune response to a particular virus, such as HIV-1, testing sensitivity to neutralizing antibodies, or screening antiviral drugs (such as protease inhibitors).

Provided herein are methods and compositions for stabilization of active agents. The active agents are distributed, mixed or embedded in a silk fibroin matrix, thereby retaining the bioactivity of the active agents upon storage and/or transportation. In some embodiments, the storage-stable vaccine-silk compositions are also provided herein.

Provided herein is a nucleic acid (e.g., messenger RNA) vaccine encoding at least one antigenic prokaryotic polypeptide linked to one or both of a viral secretion signal peptide and a transmembrane domain. Also provided are methods of vaccination against a prokaryotic infection with the nucleic acid described herein.

The present invention relates to a vaccine composition for reducing the size or volume of a target tissue, containing a genetic material that encodes a foreign antigen and, preferably, the composition can be provided as a vaccine composition for treating or preventing obesity. The vaccine composition can be provided as a composition for removing subcutaneous adipocytes.
