Product Information for Vets -
Heptavac P plus contains antigens (somatic or toxoid) against seven of the most common strains of clostridial disease as well as IRP antigens against Mannheimia haemolytica. All MSD Animal Health's sheep pasteurella vaccines contain bacteria which express a high number of iron regulated proteins (IRPs), thus mimicking the situation that occurs when the bacteria infect an animal naturally. As part of the immune response to vaccination, antibodies against these IRPs are produced which then attach to any invading bacteria, causing them to be starved of iron and die. This occurs at an early stage before the bacteria are able to produce large amounts of damaging toxins. Since all strains of Mannheimia haemolytica and Pasteurella trehalosi express similar IRPs, the vaccines also provide good cross protection against other strains of these bacteria.
The cattle respiratory vaccine, is also produced using IRP technology.
