At Vaxxinova®, we develop, manufacture and sell veterinary vaccines based upon our proprietary SRP® Technology. The innovative SRP Technology induces host immunity against cell wall components called Siderophore Receptors and Porins (SRP) which transport iron. Iron to bacteria is like oxygen to humans. By creating antibodies to SRPs, the vaccine works by starving bacteria of an essential nutrient, causing it to die. Identical SRPs are highly conserved among a host of common bacteria.
