ANTIGEN VECTORS IN THE FORM OF MULTILAMELLAR VESICLES AND COMPOSITIONS CONTAINING ANTIGENS ENCAPSULATED IN THESE VESICLES

摘要

The invention concerns an antigen vector, in particular a protein antigen,consisting of a dispersion of multilamellar vesicles within which said antigenis at least partially encapsulated, said vesicles consisting of two layerscomprising at least a surfactant, said two layers being concentric andproviding said vesicles with an onion-like structure. The invention alsoconcerns compositions containing at least an antigen against which it isdesired to produce antibodies, said antigen being partially encapsulated insuch a vector. The invention further concerns the method for preparing saidcompositions.
