The present disclosure provides compositions and methods for producing high-purity squalene from a squalene source, for example from host cells, such as yeast cells that are capable of synthesizing squalene. Further provided herein are compositions containing high-purity squalene, as well as methods of using the same in pharmaceutical formulations, such as in adjuvant formulations for use in vaccines.
