The present invention relates to the medical field, particularly to the use of new formulations of adjuvants as vaccinal antigenes. The technical objective of the present invention is precisely the development of formulations capable of raising and/or modulating the immune response of the organism to vaccinal antigenes at serum and mucus levels. In order to attain such objective, a formulation has been developed which contains as fundamental components the surface antigene of the B hepatitis virus and the acemanane in adequate proportions. As an extension of such result, formulations have been developed wherein: a) HBsAg is used as carrier of homologous and heterologous antigenes; b) systems for transmitting particulate antigens and c) soluble antigens, in combination with the acemanane in specific proportions. The formulations of this invention are applicable to the pharmaceutical industry as vaccinal formulations both for human and veterinary use.

La présente invention concerne la branche de la médecine, et plus particulièrement l'utilisation de nouvelles formulations d'adjuvants avec antigènes vaccinaux. L'objectif technique recherché par le biais de cette invention consiste, précisément, à mettre au point des formulations capables d'augmenter et/ou moduler la réponse immunitaire de l'organisme à des antigènes vaccinaux au niveau sérique et des muqueuses. Pour atteindre cet objectif, on a mis au point une formulation dont les composants fondamentaux sont l'antigène de surface du virus de l'hépatite B et l'acémanane dans des proportions appropriées. A la suite du résultat obtenu, on a mis au point des formulations, dans lesquelles: a) on utilise l'HBsAg comme porteur d'antigènes homologues ou hétérologues, b) des systèmes de transmission d'antigènes particulaires et c) des antigènes solubles, en combinaison avec l'acémanane dans des proportions spécifiques. Les formulations faisant l'objet de cette invention sont utilisées dans l'industrie pharmaceutique en tant que formulations vaccinales, indiquées pour l'être humain et les animaux.
