Entervax: Clinical Evaluation of a Bivalent Typhoid-Paratyphoid Enteric Fever Vaccine

In plain English

AI plain-English summary

A single oral pill could replace the needle for two major typhoid vaccines, if Prokarium’s Entervax passes its first human tests. Typhoid and paratyphoid fever—collectively called enteric fever—sicken millions each year, mostly in places with poor sanitation. Current injectable vaccines require cold storage, trained staff, and sterile equipment, all of which limit coverage in the remote or crisis-hit areas where the disease hits hardest. Entervax uses the Vaxonella platform to deliver two antigens in one thermostable tablet that patients can swallow themselves. If the clinical proof-of-concept succeeds, the same platform could be adapted for other vaccines—rabies, cholera, perhaps pandemic threats—without needing a fridge or a syringe. That would shift vaccine logistics from a fragile cold chain to a shelf-stable tablet, lowering cost and expanding access in low-resource settings. The project is applied development, not fundamental science; its value depends entirely on whether the tablet triggers protective immunity in humans. If it does, the impact on epidemic preparedness and routine immunisation in urbanising, antibiotic-resistant regions could be substantial.

View original technical description
Prokarium’s vision is a world where many different recombinant protein vaccines are delivered orally at reduced cost to improve uptake and prevent illness in populations across the globe. Entervax will be the first clinical proof-of-concept (CPoC) for achieving this using the Vaxonella platform. This CPoC is instrumental in broadening Vaxonella’s use through the future partnering with other vaccine developers wanting to apply our technologies. In a more connected world, with accelerating urbanization putting a strain on sanitation and empiric use of antibiotics leading to multi-drug resistant pathogens, chances for epidemics and pandemics are growing at an exponential rate. There is talk of a post-antibiotic era within our lifetimes and when we reach this, rapid deployment of prophylactic and therapeutic vaccines will be paramount. We envision that Vaxonella and Entervax will be able to play an important role in epidemic preparedness and response, because of the potential long shelf life, thermostable formulation and oral (self-) administration. Finally, this project will not only help Prokarium to become recognised for developing effective novel vaccines, it will also help to attract funding and talent to our growing biotech company.
