Pacific GeneTech Adjuvant Technology Approved for Use With Medion Vaccine in Indonesia

​​​​Pacific GeneTech (PGT), a biologics company that develops and commercializes next-generation vaccines, received an Indonesian approval for its patented “Hercules” adjuvant for use with Medion’s coryza poultry vaccine. Medion is a leading Indonesian animal health company with distribution throughout SE Asia.

Adjuvants are added to vaccines to enhance immune response to antigens. “Hercules is designed to be particularly effective in boosting mucosal immunity in orally or nasally administered vaccines, but it can also be used effectively as an injectable,” PGT CEO Tim Collard said.

Hercules will be used in Medion’s coryza vaccination program where trials show it has a better safety profile than oil-adjuvated vaccines. At the same time, it also provides good potency and duration of immunity, making it suitable for both broiler and layer birds. The product will be marketed first in Indonesia, then internationally through Medion’s distribution. Hercules will be manufactured in Indonesia in a joint development between PGT and Medion.

PGT holds the global, exclusive rights to Hercules and it is the adjuvant for all PGT’s inactivated vaccines. The adjuvant is also in the regulatory stage in the US in two PGT vaccines (for Salmonella & Eimeria) and in trials with other companies’ vaccines for multiple animal hosts.
