VACCINATION
The present invention relates to compositions for use in and methods for protecting against Herpes Zoster (HZ).
RNA MOLECULES
The present disclosure relates to RNA molecules encoding a varicella zoster virus (VZV). The present disclosure further relates to compositions comprising the RNA molecules formulated in a lipid nanoparticle (RNA-LNP). The present disclosure further relates to the use of the RNA molecules, RNA-LNPs and compositions for the treatment or prevention of herpes zoster or shingles.
VARICELLA ZOSTER VIRUS VACCINE
The present invention relates to a vaccine composition for prevention or treatment of chicken pox or Herpes zoster, the vaccine composition comprising a surface protein (gE) of Varicella zoster Virus and especially an aluminum salt as an adjuvant. The vaccine composition according to the present invention employs a protein antigen, thus showing greater outstanding stability than a live vaccine and has an optimized mixture ratio of adjuvants to elicit effective antibody induction, thereby being useful as a vaccine for preventing or treating Varicella zoster Virus-caused chicken pox or Herpes zoster.
CONSTRUCTION AND APPLICATION OF FUSION PROTEIN VACCINE PLATFORM
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.
VARICELLA ZOSTER VIRUS (VZV) VACCINE
Aspects of the disclosure relate to nucleic acid vaccines. The vaccines include at least one RNA polynucleotides having a open reading reading frame encoding at least varicella zoster virus (VZV) antigen. Methods for preparing and using such vaccines are also described.
VARICELLA ZOSTER
The present application relates to compositions capable of inducing an immune response against Varicella zoster virus, methods of administering such compositions, and methods of producing such compositions.
Method for promoting replication of bovine rhinotracheitis viruses using cold atmospheric plasma
A method for promoting replication of infectious bovine rhinotracheitis viruses using cold atmospheric plasma, including: irradiating a medium for Madin-Darby bovine kidney cells with a cold atmospheric plasma generator; adding the irradiated medium to the Madin-Darby bovine kidney cells; and adding infectious bovine rhinotracheitis viruses for incubation. The time required for treatment is 2 min allowing for a simple and rapid operation. The plasma is used for the indirect treatment of cells with a uniform process and a controllable intensity. The replication of the infectious bovine rhinotracheitis viruses in the Madin-Darby bovine kidney cells is significantly promoted by co-incubation in the treated DMEM for 1 hour, so that the high levels of infectious bovine rhinotracheitis viruses obtained can be used for vaccine production after inactivation, improving the vaccine production efficiency.
Saponin purification
Saponin extracts containing at least 93% QS-21 main peak and 0.25-3% 2018 component by UV absorbance at 214 nm, methods for making said extracts, their use as vaccine adjuvants and related aspects.
RECOMBINANT VARICELLA-ZOSTER VIRUS (VZV) VACCINE
The present disclosure discloses a recombinant varicella-zoster virus (VZV) vaccine, including a fusion protein formed by an amino acid sequence of an extracellular domain of a recombinant glycoprotein gE of a live attenuated VZV strain (OKA strain) gene and an Fc fragment of human immunoglobulin. The present disclosure further provides preparation and use of the fusion protein, a corresponding recombinant gene, a eukaryotic expression vector, etc. The fusion protein of the present disclosure has prominent immunogenicity and can induce the high-level expression of neutralizing antibodies in serum.
Vaccine compositions of herpesvirus envelope protein combinations to induce immune response
Provided are antigenic compositions and uses thereof that include at least two human herpesvirus (HHV) polypeptides involved in mediating HHV binding, fusion, and entry into host cells, such as gp350, gH, gL, and gB, or nucleic acids encoding the polypeptides. The two HHV polypeptides comprise any combination of: a gB polypeptide; a gp350 polypeptide; a gL polypeptide; and a gH polypeptide, and optionally any one or more of the following polypeptides: gp42, gM, gN, gl, gC, gE, gD, ORF68, BMRF-2, BDLF2, UL128, UL130, UL131A, and gpK8.1. Also disclosed are methods of inducing an immune response or treating or preventing an HHV infection in a subject by administering to the subject at least two of the HHV polypeptides or nucleic acid(s) encoding the same. Methods of passively transferring immunity using high-titer anti-HHV antibodies or immune cells are also disclosed.
