Abstract
A method for preparation of a shelf-stable precursor solution used to prepare a vaccine delivery system and useful for remote encapsulation of active ingredients is described. The vaccine delivery system utilizes solvent dilution microcarriers into which pathogen subunits are incorporated for delivering antigens to mucosal sites for stimulating imunoglobulin production.
