Abstract
Abstract Pure isomannide monooleate and pure aluminum monostearate are used singularly or in combination in the preparation of emulsion type adjuvant vaccines to yield an adjuvant superior to prior art adjuvants which employ commercial mannide monooleate and aluminum monostearate. Highly desirable formulations are obtained by the inclusion of pure aluminum monostearate as a stabilizer in combination with the pure isomannide monooleate.
