Mechanism of action

Fendrix contains recombinant hepatitis B surface antigen (HBsAg) combined with the AS04 adjuvant, which comprises aluminum hydroxide and MPL (monophosphoryl lipid A). This adjuvant system enhances both cellular and humoral immune responses, resulting in higher and more durable antibody titers compared to non-adjuvanted hepatitis B vaccines. The vaccine is designed to provide improved protection, particularly in populations with reduced immune response such as dialysis patients.
