Disclosed herein is a composition including a recombinant nucleic acid sequence that encodes an antibody to a Hepatitis B viral antigen. Also disclosed herein is a method of generating a synthetic antibody in a subject by administering the composition to the subject. The disclosure also provides a method of preventing and/or treating a Hepatitis B virus infection in a subject using said composition and method of generation.

The present disclosure provides methods for preparing vesicles. In some embodiments, the methods involve providing a molten mixture of vesicle forming lipids and then adding the molten mixture to an aqueous solution comprising an antigen such that antigen-containing vesicles are formed. In other embodiments, the methods involve providing a lyophilized lipid product and rehydrating the lyophilized lipid product with an aqueous solution comprising an antigen such that antigen-containing vesicles are formed. The lyophilized lipid product is prepared by melting vesicle-forming lipids to produce a molten lipid mixture and then lyophilizing the molten lipid mixture. The present disclosure also provides antigen-containing vesicle formulations prepared using these methods. The present disclosure also provides kits that include a lyophilized lipid product in a first container and an aqueous solution comprising an antigen in a second container.

The present invention is based, at least in part, on the identification of a pharmaceutical container formed, at least in part, of a glass composition which exhibits a reduced propensity to delaminate, i.e., a reduced propensity to shed glass particulates. As a result, the presently claimed containers are particularly suited for storage of pharmaceutical compositions and, specifically, a pharmaceutical solution comprising a pharmaceutically active ingredient, for example, PEDIARIX® (Diphtheria and Tetanus Toxoids and Acellular Pertussis Adsorbed, Hepatitis B (Recombinant) and Inactivated Poliovirus Vaccine), HAVRIX® (Hepatitis A Vaccine), ENGERIX-B® (Hepatitis B Vaccine (Recombinant)), TWINRIX® (Hepatitis A & Hepatitis B (Recombinant) Vaccine), EPERZAN® (albiglutide), MAGE-A3 Antigen-Specific Cancer Immunotherapeutic (astuprotimut-R), GSK2402968 (drisapersen), and HZ/su (herpes zoster vaccine).

The present invention relates to a polypeptide comprising at least three peptide fragments consisting of 10 to 50 consecutive amino acid residues of at least one wild-type allergen fused to the N- and C-terminus of a surface polypeptide of a virus of the hepadnaviridae family or at least one fragment of said surface polypeptide.

The invention relates to polynucleotides comprising the sequence of a flavivirus preceded by a sequence encoding an N terminal part of a flavivirus Capsid protein, an immunogenic protein, or a part thereof comprising a an immunogenic peptide, and a 2A cleaving peptide, and to the virus encoded by such sequences. The invention further relates to the use of such polynucleotides and viruses as vaccines.

Disclosed herein are alphavirus vectors that include neoantigen-encoding nucleic acid sequences derived from a tumor of a subject. Also disclosed are nucleotides, cells, and methods associated with the vectors including their use as vaccines.

The invention relates to the use of a polypeptide derived from the adenylate cyclase of a Bordetella sp. (CyaA-derived polypeptide) by deletion of a segment of at least 93 amino acid residues, in particular a polypeptide derived from CyaA of Bordetella pertussis, as an immunomodifying antigen of the TH1/TH17-oriented immune response in an immunogenic composition. The invention relates to a vaccine candidate comprising such CyaA-derived polypeptide, either in an acellular immunogenic composition for active immunization against a condition causally related to the infection of a host by Bordetella sp. or in a combination composition encompassing said acellular immunogenic composition.

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.

The present invention relates to compositions and methods for the prevention, treatment, and diagnosis of Hepatitis B virus (HBV) infection, and discloses peptides, polypeptides, and polynucleotides that can be used to stimulate a CTL response against HBV infection. The peptide and/or proteins of the invention may be used as a therapeutic drug to stimulate the immune system to recognize and eliminate HBV infection in infected cells or as a vaccine for the prevention of disease.

The invention is directed to Muramyl Dipeptide (MDP) derivative compounds of structural Formula-VIII, a process for synthesis, intermediates used in the synthesis and use thereof:

##STR00001##

wherein, R can be a linear or branched alkyl, an aryl, a substituted aryl, or an alkoxy alkyl. These compounds possess excellent pharmacological properties, in particular immunomodulating properties for use as adjuvant in vaccine formulations. These compounds are particularly useful as adjuvants in vaccines.
