SPI Pharma has extensive experience and knowledge of aluminum hydroxide chemistry, with more than 70 years for antacid forms and more than 20 years for VAC gels as a vaccine adjuvant. This expertise makes a difference in terms of consistency throughout our products with respect to compliance, morphology, particle size distribution, and protein adsorption capacity.
SPI Pharma’s adjuvants enable vaccines to help eradicate disease, secure food supply, reduce the threat of disease transmission, and/or improve the health of livestock and pets.
We have served the industry for decades, supplying major vaccine producers with continuous process improvement and innovation (VAC high adsorption), technical support, willingness to optimize and work with customers.

Higher Adsorption Vaccine Adjuvants
The vaccine adjuvant manufacturing process has been optimized to create an adjuvant with a higher protein adsorption capacity, a finer particle size and a narrower pH range. These characteristics make VAC 20 HA a high-performance adjuvant compared to other regular adjuvants.
Standard Vaccine Adjuvants
SPI Pharma offers a range of aluminum hydroxide gel VAC grades for adsorption (pseudo-boehmite form) for use as a vaccine adjuvant. It is used to bind negatively charged antigens.
