The present invention relates to a Varicella zoster virus fusion protein and an immunogenic composition comprising same and, more specifically, to a fusion protein comprising the glycoprotein E (gE) of Varicella zoster virus (VZV) and a constant region of an immunoglobulin molecule, and an immunogenic composition comprising same. The present invention not only remarkably increases a Varicella zoster virus-specific cell-mediated immune response, but also exhibits the effect of rapidly and potently inducing an immune response and sustaining the immune response for a long period of time, compared to preexisting vaccines, thereby can be usefully used to prevent Varicella zoster-related diseases.

Disclosed herein are coronavirus Spike (S) proteins and nanoparticles comprising the same, which are suitable for use in vaccines. The nanoparticles present antigens from pathogens surrounded to and associated with a detergent core resulting in enhanced stability and good immunogenicity. Dosages, formulations, and methods for preparing the vaccines and nanoparticles are also disclosed.

The present application is related to cancer immunotherapy, e.g. stimulation of T cell mediated anti-tumor therapy. Accordingly, described herein are methods of inducing or enhancing an adaptive immune response to a cancer in a subject and methods of treating cancer in a subject. In some embodiments, the methods hyperactivate dendritic cells (DCs), which induce T helper type I (TH1) and cytotoxic T lymphocyte (CTL) responses in the absence of TH2 immunity.

A pharmaceutical composition comprising: i) a herpes gE protein, an active fragment of the protein, a variant of the protein, or a mixture of at least two of them; ii) an immunostimulatory composition comprising a saponin and a CpG oligodeoxynucleotide, or consisting of an adjuvant comprising a saponin and a CpG oligodeoxynucleotide. Use of the pharmaceutical composition in the preparation of a medicament for preventing and/or treating a varicella-zoster virus infection and/or a varicella-zoster virus mediated disease. The pharmaceutical composition achieves an unexpected technical effect and can mediate a stronger immune response.

Disclosed herein are coronavirus Spike (S) proteins and nanoparticles comprising the same, which are suitable for use in vaccines. The nanoparticles present antigens from pathogens surrounded to and associated with a detergent core resulting in enhanced stability and good immunogenicity. Dosages, formulations, and methods for preparing the vaccines and nanoparticles are also disclosed.

The invention is directed to a coding RNA for a Rotavirus vaccine. The coding RNA comprises at least one coding region encoding at least one antigenic peptide or protein of a Rotavirus, in particular VPS* of a Rotavirus, or immunogenic fragment or immunogenic variant thereof. The present invention is also directed to compositions and vaccines comprising said coding RNA in association with a polymeric carrier, a polycationic protein or peptide, or a lipid nanoparticle (LNP). Further, the invention concerns a kit, particularly a kit of parts comprising the coding RNA, or the composition, or the vaccine. The invention is also directed to a kit or kit of parts, medical treatments, and the first and second medical uses.

Compositions are disclosed that include alum and a non-liposome, non-micelle particle, where the particle comprises a lipid, a sterol, a saponin, and an optional additional non-alum adjuvant, wherein the particle is optionally bound to the alum, and the use of the compositions as vaccine adjuvants and methods for eliciting immune responses.

The present disclosure provides a type A foot-and-mouth disease virus-like particle antigen assembled by VP2, VP3 and VP1 antigen proteins of an epidemic strain of type A foot-and-mouth disease virus. The type A foot-and-mouth disease virus VP2 antigen protein is encoded by a nucleotide sequence shown in SEQ ID No. 1 or its degenerate sequence, the type A foot-and-mouth disease virus VP3 antigen protein is encoded by a nucleotide sequence shown in SEQ ID No. 2 or its degenerate sequence, and the type A foot-and-mouth disease virus VP1 antigen protein is encoded by a nucleotide sequence shown in SEQ ID No. 3 or its degenerate sequence.

Antigenic polypeptides derived from a naturally occurring horn fly protein, and nucleic acid molecules encoding the polypeptides, are described. The polypeptides elicit an immune response which, in turn, produces detrimental effects in horn flies feeding on vaccinated cattle. Thus, the present disclosure provides a novel horn fly vaccine.

The present disclosure encompasses immunogenic/therapeutic compositions including Globo series antigens (SSEA-4, Globo H or SSEA-3) glycoconjugates and therapeutic adjuvants (OBI-821 or OBI-834) as well as methods of making and using the same to treat proliferative diseases such as cancer. The therapeutic conjugates include an antigen linked to a carrier. In particular, the therapeutic conjugates include a SSEA-4, Globo H or SSEA-3 moiety and a KLH moiety subunit linked via a linker. The therapeutic compositions are in part envisaged to act as cancer vaccines (single valent, bi-valent or tri-valent vaccines) for boosting the body's natural ability to protect itself, through the immune system from dangers posed by damaged or abnormal cells such as cancer cells. Exemplary immune response can be characterized by reduction of the severity of disease, including but not limited to, prevention of disease, delay in onset of disease, decreased severity of symptoms, decreased morbidity and delayed mortality.
