Vaccine Adjuvant: Squalene-Oil-in-water

AddaVax™ is a squalene-based oil-in-water nano-emulsion with a formulation similar to MF59® that has been licensed in Europe for adjuvanted flu vaccines [1].

Squalene is an oil more readily metabolized than the paraffin oil used in Freund’s adjuvants [1]. Squalene oil-in-water emulsions, such as MF59®, elicit both cellular (Th1) and humoral (Th2) immune responses [2, 3]. This class of adjuvants is believed to act through recruitment and activation of APC and stimulation of cytokines and chemokines production by macrophages and granulocytes [1].

AddaVax™ is VacciGrade™ (preclinical grade) for research use only, not for use in humans.

MF59® is a registered trademark of Novartis, and is used for comparative purposes only. AddaVax™ is not made by, affiliated with, sponsored by or endorsed by Novartis. Novartis has not evaluated or approved the representations contained herein.
