Method for enhancing the immunogenicity of an immunogenic compound or hapten, and use thereof for preparing vaccines

• The present invention relates to a process for improving the immunogenicity of an immunogen, an antigen or a hapten, when it is administered to a host, independently of the mode of administration, characterized in that the said antigen or hapten is coupled covalently to a support molecule in order to form a complex, and in that this support molecule is a polypeptide fragment which is able to bind specifically to mammalian serum albumin. The invention also relates to the use, as a medicament, of the product which can be obtained in this way.
