Veterinary Vaccines and Their Delivery Systems

The major aims of veterinary vaccines are to improve the health and welfare of animals, increase production of farm animals in an economic manner, and prevent transmissions of infectious diseases from both domestic animals and wildlife to the humans. The developments of veterinary vaccines are proceeding through genetically engineered organisms, vectored antigen formulations, and naked DNA injections. These veterinary vaccines have a major impact not only on animal health but also on human health through preventing animal-to-human transmission of infectious diseases. The constant interaction between human and animals researchers will be of major importance for finding new technologies. There are so many severe diseases that are spread from the domestic and wild animals to the human, so it is important to be concerned about the immunization processes of animals.
