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 invention provides herpesviruses, such as EBV, which lack at least one viral miRNA. Such herpesviruses lacking at least one viral miRNA are advantageously not capable of packaging their genome into the capsid, thereby producing HVLPs, which are substantially free of their herpesvirus genome or the nucleic acid molecule encoding the proteinaceous part of the HVLP and viral miRNA. Such HVLPs may be used as vaccine.

Herpes simplex virus (HSV) ribonucleic acid (RNA) vaccines, as well as methods of using the vaccines and compositions comprising the vaccines. In a preferred embodiment, the vaccine is formulated as a lipid nanoparticle comprising at least one cationic lipid.

The present invention belongs to the field of biopharmaceutics and in particular relates to a pharmaceutical composition. The pharmaceutical composition comprises a hepatitis B surface antigen, a hepatitis B core antigen, and an immunostimulatory composition, wherein the immunostimulatory composition comprises a saponin and a CpG oligodeoxynucleotide, or consists of an adjuvant comprising a saponin and a CpG oligodeoxynucleotide.

Provided herein are compositions and methods for vaccination and research applications. In particular, provided herein are non-neuroinvasive herpesviruses and alpha herpesviruses and uses thereof.

The present invention provides recombinant herpesvirus of turkeys (HVT) vectors that contain and express antigens of avian pathogens, compositions comprising the recombinant HVT vectors and polyvalent vaccines comprising the recombinant HVT vectors. The present invention further provides methods of vaccination against a variety of avian pathogens and method of producing the recombinant HVT vectors.

The present invention relates to viral Fc receptor or immunogenic fragments thereof for treating a viral infection in a subject and, in particular, a herpes vims infection. The present invention also relates to a heterodimer comprising or consisting of an Fc receptor from a HSV vims or an immunogenic fragment thereof and a binding partner from said HSV vims or a fragment thereof, for use in therapy.

A modified protein of a herpes simplex virus (HSV) envelope glycoprotein B (gB), in which at least one non-neutralizing antibody-inducing epitope (non-neutralizing epitope) present in domain IV and domain I of wild-type HSV gB is inactivated (de-epitoped).

The disclosure relates to HSV glycoprotein E antigenic peptide constructs and HSV protein vaccines, as well as methods of using the vaccines and compositions comprising the vaccines. The present invention directed to immunogenic polypeptides of use for a vaccine against Herpes Simplex Vims (HSV). The polypeptides are glycoprotein E peptides that are mutated to reduce their binding to antibody Fc domain.

The present invention provides vaccines for treating or preventing a herpes simplex virus infection and methods of using and making the vaccine. Further provided are recombinant herpes simplex virus genomes, recombinant viruses, and immunogenic compositions.
