摘要:
A purified antigen of T. gondii having a molecular weight of 54-kDa (as determined by Western blotting) is provided which is reactive with antibodies raised against a recombinant protein obtained by expression of a defined T. gondii cDNA (Figure 2) in a host cell; also provided are immunogenic fragments of the 54-kDa antigen. Recombinant DNA encoding the 54-kDa antigen, host cells for expression of such DNA, a vaccine for treating or preventing toxoplasmosis infection in humans and animals, and test kits for detection of T. gondii antigen or antibody are also described.
摘要:
A vaccine formulation for the treatment or prophylaxis of hepatitis, especially hepatitis B, infections is provided comprising the hepatitis antigen and a suitable carrier such as alum in combination with 3-O-deacylated monophosphoryl lipid A. Combination vaccines including the vaccine formulation are also described.

摘要:
A vaccine for protection against whooping cough which comprises protein encoded by a B. pertussis toxin amino acid coding sequence containing an entire or truncated B. pertussis toxin S1 subunit amino acid coding sequence which contains a modification of the tryptophan residue at amino acid position 26.
摘要:
A multi-valent vaccine composition is described comprising a whole-cell pertussis component, tetanus toxoid, diphtheria toxoid, and a low dose of a conjugate of the capsular polysaccharide of H. influenzae b.
摘要:
The present invention relates to the field of, engineered Gram-negative bacterial strains that have outer-membrane vesicle shedding properties, and vaccine compositions comprising these bacteria or vesicles. The present invention provides a hyperblebbing Gram-negative bacterium which has been genetically modified by either or both processes selected from a group consisting of: down- regulation of expression of one or more tol genes; and mutation of one or more gene(s) encoding a protein comprising a peptidoglycan-associated site to attenuate the peptidoglycan-binding activity of the protein(s).

摘要:
The invention provides a monovalent influenza vaccine comprising a low dose of egg-derived influenza virus antigen from an influenza virus strain that is associated with a pandemic outbreak or has the potential to be associated with a pandemic outbreak, in combination with an aluminium adjuvant. The invention also provides vaccine kits comprising a combination of a parenteral and a mucosal influenza vaccine, wherein the combined dose of antigen is no more than the conventional antigen dose. Also provided are methods for preparing the vaccines.
摘要:
The present invention relates to novel vaccine formulations suitable for oral administration. The vaccine formulations are in a solid form comprising antigen and suitable excipients, which after insertion into the mouth, rapidly dissolve in saliva, thereby releasing the vaccine into the mouth. Specifically, the solid form may consist of a cake of vaccine which is formed from a liquid solution or suspension by sublimation, preferably sublimation by lyophilisation. Preferred vaccines are those containing antigens which are or are derived from pathogens that normally infect or invade the host through a mucosal membrane, or those vaccines that further comprise an antacid. Particularly preferred vaccines are combination vaccines that comprise more than one antigen, and more preferably when the antigens are from more than one pathogen.
摘要:
The present invention relates to efficient devices for administration of pharmaceutical agents into the skin of the human body. In particular the present invention provides devices for vaccination into the skin. The present invention provides a pharmaceutical agent delivery device having skin-piercing portion comprising a solid reservoir medium containing the pharmaceutical agent, wherein the reservoir medium is coated onto the skin piercing portion. alternatively, the skin piercing portion may consist of the solid pharmaceutical agent reservoir medium. The pharmaceutical delivery devices are proportioned such that agent is delivered into defined layers of the skin, and preferred delivery devices comprise skin-piercing portions that deliver the pharmaceutical agent into the epithelium or the dermis. Preferred reservoir media comprise sugars, and in particular stabilising sugars that forms a glass such as lactose, raffinose, trehalose or sucrose. Furthermore, vaccine delivery devices for administration of vaccines into the skin are provided, methods of their manufacture, and their use in medicine.
