Abstract: The present invention relates to oil-in-water emulsions, their use as adjuvants, and pharmaceutical, immunologic, or vaccine compositions that may comprise the same. In one embodiment, the oil-in-water (O/W) emulsion may comprise an aqueous solution containing an immunogen, a mineral oil, a non-ionic lipophilic ethoxylated fatty alcohol and a non-ionic hydrophilic surfactant. In another embodiment, the oil-in-water (O/W) emulsion may comprise an aqueous solution containing an immunogen, a non-ionic lipophilic surfactant, a mineral oil and a non-ionic hydrophilic ethoxylated fatty alcohol. The present invention also encompasses a method of making a vaccine composition using the adjuvant of the instant invention, the vaccine composition so obtained and methods of use.

Abstract: Injectable water-in-oil emulsion possessing immunity adjuvant activity and which can be used in man and animals as vaccine or an immunological medicament comprising an oily phase comprising an oil , an aqueous phase and at least one emulsifier, wherein the oil of said oily phase is a substantially metabolizable oil or a mixture of substantially metabolizable oils and said emulsifiers or emulsifiers providing with said metabolizable oil a stable emulsion having immunity adjuvant activity and a viscosity of less than 400 mPa.s at 25° C.

Abstract: Method for improving the organoleptic qualities of the meat from uncastrated male domestic animals, vaccines which are usable in this method, new peptide, in particular, for producing these vaccines and vaccination kit relating thereto.The method for improving the organoleptic qualities, especially the smell, taste and tenderness, of the meat from uncastrated male domestic animals comprises, shortly before slaughter of the animal in question, abolition of the action of the androgenic and non-androgenic steroids by active or passive anti-LHRH immunoneutralization, while the advantages linked to the male character of the animal are maintained virtually up to slaughter. The vaccines comprise, as a peptide, natural LHRH or a peptide of formula Trp - Ser - Tyr - Gly - Leu - Arg - Pro - Gly - NH.sub.2, coupled to an immunogenic carrier protein.
