The invention relates to a stability and biocompatibility-optimized adjuvant (SBA) for enhancing the humoral and cellular immune response by jointly injecting said adjuvant with one or more antigens. The adjuvant consists of particles based on solid lipids or solid lipid mixtures and can be used in the production of more efficient and compatible vaccines, the inoculation of human beings and animals and for obtaining antibodies. The strength of the immune response can be modulated in a targeted manner and additionally adapted to the specific species by selecting the size, charge and surface characteristics of the particles. Other adjuvants, e.g. molecular adjuvants such as GMDP, can be added to the SBA, whereby the cellular immune response is additionally enhanced. The SBA is more effective and cost-efficient and easier to use than existing products and is well tolerated in vivo.

L'invention concerne un adjuvant à stabilité et biocompatibilité optimisées servant à augmenter la réponse immunitaire humorale et cellulaire par injection conjointe avec un ou plusieurs antigènes. L'adjuvant selon l'invention est constitué de particules à base de lipides ou de mélanges lipidiques solides et convient à la production de vaccins plus efficaces et mieux tolérés, aux vaccinations des hommes et des animaux, mais également à l'obtention d'anticorps. On peut moduler de manière ciblée la force de la réponse immunitaire par le choix de la taille et de la charge des particules ainsi que des propriétés de surface, et l'adapter ainsi à chaque espèce. On peut ajouter à l'adjuvant biocompatible stable (SBA) selon l'invention d'autres adjuvants comme, par exemple, des adjuvants moléculaires tels que le GMDP, ce qui entraîne en outre l'augmentation de la réponse immunitaire cellulaire. L'adjuvant biocompatible stable selon l'invention est plus puissant, moins coûteux et d'utilisation plus simple que les produits existant déjà ; en outre, il est bien toléré in vivo.
