Different Species – Different Routes – Different Vaccines

Each animal species is different, as are its feeding habits, its environments, and its microbiome. Understanding an animal's digestive tract is essential in delivering vaccines to the right place in the animal's intestines.

Field Mouse

Diverse genetic background
Can carry multiple pathogens
Outdoors
Large numbers
Multiple environments
Uncontrolled eating habits
Single-stomach digestive tract

species-canine

Canine

Mixed-breed or pure-breed
Indoor or outdoors
Multiple sizes / breeds
Large numbers
Controlled or uncontrolled eating habits
Strong preferences for certain foods
Single-stomach digestive tract

Poultry

Controlled breeding
Food animal
Multiple stocks and lifespans (breeder, broiler, layer)
Large numbers
Special feed / water requirements (focus on nutrition)
Single stomach with crop digestive tract

Livestock

Controlled breeding
Multiple breeds / sizes
Food animal (meat and milk)
Long lifespan
Special feed / water requirements (focus on nutrition)
Multi-stomached digestive tract

We translate what we know about digestive systems to develop human vaccines as well, including a novel orally delivered flu vaccine that can be delivered to your home.

COMPONENTS

Substrate Component Features

Integration of species-specific substrates that allows integration of multiple vaccines, therapeutics, and additives, each of which may be incorporated as an amalgam or as a spray-on.
Targeted gut placement that maintains in harsh GI environments.
Coarse textures, providing mechanical stimulation of the animal’s innate immune system.
Kibble, chewables; effervescent tablets, and powders.

Bacterial Expression Vehicle Component

Vehicle inactivation (non-GMO, thermostability).
Recombinant antigen expression system (AVOIDS use of infectious agents).
Molecular adjuvantization (cost reduction / no chemical complications).
Microbiome friendly
