Emulsion Adjuvants for Use in Veterinary Vaccines.

The use of emulsion as adjuvants is widely used in veterinary vaccines. Emulsion adjuvants are inexpensive, stable, and relatively easy to prepare into vaccine formulations. Here we describe the preparation of oil-in-water emulsion adjuvant that has been shown to enhance immune responses and protect against diseases in pigs. This emulsion adjuvant and its variations could potentially be used alone or in combination with other adjuvants in veterinary vaccine formulations.
