Abstract
A novel method for the mucosal administration of a substance to a mammal is provided. The method comprises contacting a mucosal surface of the mammal with the substance in combination with a Biovector. The Biovector has a core that comprises a natural polymer, or a derivative or a hydrolysate of a natural polymer, or a mixture thereof. A preferred natural polymer is a polysaccharide or an oligosaccharide. The core is optionally coated with an amphiphilic compound, such as a lipid.
