Intervacc's innovative technology utilises fusion proteins in vaccines to generate broad-acting immune responses that provide protection to animals from complex bacterial diseases. Streptococcus suis causes meningitis, sepsis and arthritis in young piglets, leading to significant costs to the pig industry throughout the world. Early proof-of-concept studies found that the consumption of colostrum from sows that were vaccinated with Intervacc's prototype vaccine against Streptococcus suis provided significant levels of protection to piglets at 4 and 7 weeks of age against challenge with a virulent strain of Streptococcus suis.

Testa Center provide access to a lab environment with a modern, pilot-scale testbed to optimise the scale-up processes required to manufacture biologics. The new industrial research project provides a grant to Intervacc of 800k SEK funded by Vinnova, which corresponds to about 70% of the cost of this development phase at Testa Center.

"We are very pleased to be extending our work with Testa Center to begin the development of the scale-up processes required to produce our prototype vaccine to protect piglets against Streptococcus suis infection," said Dr. Andrew Waller, CSO of Intervacc, "this new project represents another step on our path towards easing the burden caused by this important swine pathogen, in addition to minimising the requirement to treat this infection with antimicrobial agents."

"At Testa Center we are delighted to be providing our expertise and facilities to help Intervacc optimise the small-scale manufacturing processes of this first vaccine component in preparation for further manufacturing and testing," stated Dr. Jesper Hedberg, CEO of Testa Center.
