vaccine development


For more than 80 years Croda has been dedicated to safe and effective adjuvants suitable for use in both human and veterinary vaccines.

To this day, one of Croda’s core competencies is to develop, manufacture and market high-quality adjuvants and be a dedicated and reliable partner for our customers. This unique historical focus has formed a strong market position and brands such as AlhydrogelAdju-Phos and Quil-A are widely recognised in the vaccine industry.

Vaccine adjuvants are a highly heterogenous collection of compounds that share one functional characteristic: the ability to enhance immune responses.
