The present invention relates to the treatment of autoimmune and allergic diseases by oromucosal administration of a formulation consisting of an optimized combination of antigen, tolerizing agent and mucoadhesive carrier for each immune disease indication.

Disclosed are methods for the treatment of non-fatty liver disease (NAFLD). The methods involve the administration to a subject in need thereof of a pharmaceutical formulation comprising an HSP27 polypeptide or immunologically equivalent portion thereof, or an anti-HSP27 antibody or a functional anti-HSP27 antibody fragment, or a mixture of an HSP27 polypeptide or immunologically equivalent portion thereof, and an anti-HSP27 antibody or a functional anti-HSP27 antibody fragment.

A composition for treating and/or preventing Hepatitis B virus infection and Hepatitis B virus infection mediated diseases and the method thereof are provided. In some embodiments, the composition includes a polyriboinosinic acid-polyribocytidylic acid (PIC), at least one antibiotic or polyamide compound, at least one positive ion, and Hepatitis B virus surface antigen. In some embodiments, the composition includes PIC, at least one antibiotic or polyamide compound, at least one positive ion, Hepatitis B virus surface antigen and Hepatitis B virus core antigen. The present disclosure also relates to a method of treating and/or preventing Hepatitis B virus infection, particularly for treating chronic HBV infection.

To develop a universal and long-lasting influenza or other pathogens vaccine has been a mission impossible goal in the life science and health field. Applicants disclose, herein, vaccines prepared against SARS-COV-2, an influenza A strain vaccine prepared from a 1934 influenza virus (A/PR/8/34 H1N1, Puerto Roca, 1934), and an influenza B strain vaccine prepared from a 1940 influenza virus. The disclosed vaccine induces production of broadly neutralizing antibodies in mice. The presently disclosed vaccine is able to inhibit two other influenza A strains: a 2009 influenza H1N1 virus collected from Los Angeles (A/California/07/2009) and a 2014 influenza H3N2 virus collected from Hong Kong (A/Hongkong/4801/2014). Applicants also describe an influenza B strain vaccine prepared from a B strain virus from a 1940 patient in USA (B/L11/40). The B strain vaccine also produced broadly neutralizing antibodies, in this case against a B strain from Colorado 2017 (B/Colorado/2017). Applicant's methods and compositions are not only useful in creating influenza vaccines with broad activity against other influenza subtypes but also be efficient to generate long-lasting SARS-CoV-2 vaccines against emerging new variants either through recombined protein antigens from SARS-CoV-2 or inactivated SARS-CoV-2 virus.

A plant produced vaccine for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is provided where the Spike protein of the virus is expressed in a plant by introducing into a plant a construct comprising a promoter preferentially directing expression to seed of said plant, a nucleic acid encoding the Spike protein and a nucleic acid targeting expression to the endoplasmic reticulum of the plant. The plant expresses the 51 polypeptide at levels of at least 10 mg/kg of seed of said plant. When orally administered to an animal, a protective response is observed including a serum antibody response.

The present invention relates to, in part, compositions comprising improved flagellin derived constructs and methods of using for vaccination, including adjuvants comprising flagellin-based agents.

The present invention relates to the construction and application of a fusion protein vaccine platform. The present invention provides a vaccine, comprising a fusion protein containing an interferon-target antigen-immunoglobulin Fc region (or antibody) and a Th cell helper epitope. The present invention also relates to use of a fusion protein containing an interferon-target antigen-immunoglobulin Fc region (or antibody) and a Th cell helper epitope in the preparation of prophylactic or therapeutic compositions. The vaccine of the present invention can be produced by eukaryotic cell expression systems to prepare wild-type and various mutant antigen vaccines, and vaccination by means of subcutaneous/muscular or nasal or other routes can lead to a strong immune response to a body. The vaccine of the present invention can be used as a prophylactic or therapeutic vaccine.

The present disclosure is directed to improved virus-like particle (VLP) compositions and vaccines for use in inducing an immune response and/or protective immunity against a Chikungunya virus (CHIKV) infection in a subject, e.g., by inducing a neutralizing antibody response against CHIKV in a subject within 7 days after administration of a single dose of the composition or vaccine.

Particles offering multiple doses of an active agent to a subject via a single administration of the active agent to the subject are provided. The particles comprise multiple layers, including two dosing layers each having the active agent and an intervening layer that separates the two dosing layers, and provide a first dose of the active agent from the dosing layer covering the intervening layer upon exposure to an aqueous environment after the particles are administered to the subject, and later a second dose of the active agent from the dosing layer covered by the intervening layer after the intervening layer degrades in the body of the subject. Methods for preparing the particles are also provided. Methods for treating or preventing a disease or disorder in a subject in need thereof with two or more doses of an active agent via a single administration to the subject are further provided.
