Abstract

A vaccine adjuvant composition of an oil-in-water submicron emulsion that has about 0.5 to 50% of a first component of an oil, about 0.1 to 10% of a second component of an emulsifier, about 0.05 to 5% of a nonionic surfactant, about 0.00001 to 1% of an immunogen, and an aqueous continuous phase. This submicron emulsion has a mean droplet size in the range of between about 0.03 and 0.5 μm, and preferably 0.05 and 0.2 μm.
