The present invention aims to provide a composition for promoting immunity induction and a vaccine pharmaceutical composition which are universally usable for inducing immunity to various antigens and capable of exerting a high immunity inducing effect. The present invention relates to a composition for promoting immunity induction containing at least one nuclear receptor ligand and also relates to a vaccine pharmaceutical composition for inducing immunity containing an antigen and a composition for promoting immunity induction that is at least one nuclear receptor ligand.

Stable, immunogenic combination vaccine(s) comprising a mixture of antigens for prevention and prophylaxis of infections caused by Rotavirus, Poliomyelitis virus, Haemophilus influenzae, Corynebacterium diphtheriae, Clostridium tetani, Bordetella pertussis and Hepatitis B virus. A multivalent combination vaccine comprises i) significantly dose-reduced Salk-IPV or Sabin-IPV (IPV) antigens prepared by methods of formaldehyde inactivation and alum hydroxide adsorption resulting in maximum D-antigen recovery; ii) Injectable heat inactivated Rotavirus antigen(s) providing broad cross-protective immunity among human rotavirus strains; iii) Hib PRP-carrier protein conjugate having improved stability and immunogenicity; iv) whole cell pertussis antigen with improved immunogenicity and stability; and v) Homogenous fractions of Diphtheria and Tetanus toxoids. Such stable and immunogenic vaccine compositions are made by i) individually adsorbing dose reduced IPV, IRV antigens on alum hydroxide and keeping other antigen(s) unadsorbed or adsorbed on alum phosphate, alum hydroxide, or a combination thereof; and ii) using an order of addition of antigens during blending.

The present invention relates to a therapy for treating or preventing several diseases in animals, based on the administration of a highly concentrated avian derived immunoglobulins formulation, obtained from the egg yolk from hens previously hiper-immunized with a vaccine formulation comprising infectious agents or toxins antigens, a light mineral oil and a particulate adjuvant.

Nucleic acids encoding rotavirus VP7 fusion proteins and rotavirus-like particle (RLPs) comprising the rotavirus VP7 fusion proteins are provided. Methods for rotavirus VP7 fusion protein and RLP production in plants are also described. The VP7 fusion protein comprises a first sequence encoding a 7-1a subdomain, a second sequence encoding a 7-2 domain and a third sequence encoding a 7-1b subdomain; wherein the sequence of the 7-2 domain is derived from a first rotavirus strain and the sequence of the 7-1a subdomain, the sequence of the 7-1b subdomain or the sequence of the 7-1a subdomain and the sequence of the 7-1b subdomain are derived from a second rotavirus strain.

The present invention relates to thermostable quick-dissolving thin films comprising a biological moiety and an excipient mix which are suitable for the formulation of biological moieties such as viral vaccines, to methods for manufacturing such thermostable quick-dissolving thin films, and to their use in therapy. The excipient mix comprises one or more water-soluble polymer(s), a sugar selected from sucrose, trehalose and a combination thereof, a metal ion, a carboxylate, and a buffering agent.

A buffer free, acid stable, low dose volume rotavirus vaccine is disclosed. The vaccine is available in dose volume of less than 1 ml per dose for oral administration and it is without any buffer. The vaccine also does not require pre or post administration of any antacid at the time of oral administration of the vaccine to the subject to neutralize the stomach acid. The vaccine exemplifies nominal drop in vaccine titer at pH 2-4 for a time span of 30 minutes. The vaccine is stable at −20° C. for at least 60 months.

The present invention relates to recombinantly constructed polypeptides useful for preparing vaccines, in particular for reducing one or more clinical signs caused by an infection with at least one pathogen, such as clinical signs caused by a viral infection. More particular, the present invention is directed to a polypeptide comprising a Circoviridae capsid protein linked to a heterologous protein or fragment thereof, and to chimeric virus-like particles composed of such polypeptides. In one example, a fusion protein is provided which comprises PCV2 ORF2 protein linked to an immunogenic fragment of rotavirus VP8 protein, and which is usable for reducing one or more clinical signs, mortality or fecal shedding caused by a rotavirus infection in swine.

The present invention relates to recombinantly constructed polypeptides useful for preparing vaccines, in particular for reducing one or more clinical signs caused by a rotavirus infection. More particular, the present invention is directed to a fusion protein comprising in N- to C-terminal direction (i) an immunogenic fragment of a rotavirus VP8 protein and (ii) an immunoglobulin Fc fragment such as, for example, an IgG Fc fragment, wherein said fusion protein is usable in a method of reducing one or more clinical signs, mortality or fecal shedding caused by a rotavirus infection in swine.

The invention relates to a truncated rotavirus VP4 protein, a sequence encoding the same, a method for preparing the same, and a pharmaceutical composition and a vaccine comprising the protein, wherein the protein, the pharmaceutical composition and the vaccine are useful for preventing, alleviating or treating rotavirus infection and a disease caused by rotavirus infection, such as rotavirus gastroenteritis and diarrhea. The invention further relates to use of the protein in the manufacture of a pharmaceutical composition or a vaccine for preventing, alleviating or treating rotavirus infection and a disease caused by rotavirus infection, such as rotavirus gastroenteritis and diarrhea.

Methods of thermally inactivating a rotavirus are provided according to the present invention which include exposing the rotavirus to a temperature in the range of about 50° C.-80° C., inclusive, for an incubation time sufficient to render the rotavirus incapable of replication or infection. The thermally inactivated rotavirus is antigenic and retains a substantially intact rotavirus particle structure. Vaccine compositions and methods of vaccinating a subject against rotavirus are provided which include generation and use of thermally inactivated rotavirus.
