Abstract
The present invention relates to targeted polymerized liposomes for oral and/or mucosal delivery of vaccines, allergens and therapeutics. In particular, the present invention relates to polymerized liposomes which have been modified on their surface to contain a molecule or ligand which targets the polymerized liposome to a specific site or cell type. More particularly, the invention relates to the use of polymerized liposomes modified to contain a carbohydrate or lectin on their surface.
