Animal vaccines refer to biologics prepared artificially using one or more pathogens, with the aim of preventing and controlling animal diseases. These biologics are administered into animals through methods such as injection, introducing the pathogens or their corresponding antigens into the animal's body. This stimulates the host's immune response, leading to the development of immunity, ultimately preventing and controlling animal diseases. Animal vaccines are a crucial tool for preventing and controlling animal diseases. They can reduce disease incidence in animals, minimize the occurrence and spread of epidemics, safeguard animal health and production, and also have significant implications for human health and safety. With advancements in technology and an increasing focus on animal health and welfare, research and application of animal vaccines are receiving growing attention. This review aims to explore various aspects of animal vaccines, including their definition, classification, and current developments, aiming to gain a deeper understanding of the importance and application value of animal vaccines, as well as the necessity of vaccine research and development.
