Abstract

Background: Although a number of investigation have been carried out to find alternative adjuvants to aluminum salts in vaccine formulations, they are still extensively used due to their good track record of safety, low cost and proper ADJUVANTICITY with a variety of antigens. Adsorption of antigens onto aluminum compounds depends heavily on electrostatic forces between adjuvant and antigen. Commercial recombinant protein HEPATITIS B VACCINEs containing aluminum hydroxide as adjuvant is facing low induction of immunity in some sections of the vaccinated population. To follow the current global efforts in finding more potent HEPATITIS B VACCINE formulation, ADJUVANTICITY of ALUMINUM PHOSPHATE has been compared to aluminum hydroxide. Materials and methods: The adjuvant properties of aluminum hydroxide and ALUMINUM PHOSPHATE in a vaccine formulation containing a locally manufactured hepatitis B (HBs) surface antigen was evaluated in Balb/C mice. The formulations were administered intra peritoneally (i.p.) and the titers of antibody which was induced after 28 days were determined using ELISA technique. The geometric mean of antibody titer (GMT), seroconversion and seroprotection rates, ED50 and RELATIVE POTENCY of different formulations were determined. Results: All the adjuvanicity markers obtained in ALUMINUM PHOSPHATE formulation were significantly higher than aluminum hydroxide. The geometric mean of antibody titer of ALUMINUM PHOSPHATE was approximately three folds more than aluminum hydroxide.Conclusion: ALUMINUM PHOSPHATE showed more ADJUVANTICITY than aluminum hydroxide in HEPATITIS B VACCINE. Therefore the use of ALUMINUM PHOSPHATE as adjuvant in this vaccine may lead to higher immunity with longer duration of effects in vaccinated groups.
