Prokarium Ltd is a UK vaccine development company developing a dual travellers' diarrhea (ETEC) and typhoid vaccine, as well as a C.difficile and a Chlamydia vaccine.

All of Prokarium's vaccines are oral vaccines based on Vaxonella, a platform that enables targeted production of vaccines from within the body's own immune cells, thus triggering all arms of the immune system with little or no side effects, while saving up to 70% of manufacturing costs. Prokarium has laboratories in Keele, Staffordshire and an office in London, UK.

The team experience stretches from microbial genetics and immunology to mergers and acquisitions in pharma, business development and accounting.
