The technical purpose of the invention is realized by the following technical scheme: a lyophilized live vaccine for animals comprises live vaccine antigen and lyophilized protectant, wherein the lyophilized protectant comprises fibronectin and riboflavin.
By adopting the technical scheme, the freeze-dried live vaccine for the animal comprises the live vaccine antigen and the freeze-dried protective agent, the live vaccine antigen is attenuated after attenuation treatment, the toxicity is weakened, the live vaccine antigen is inoculated into the animal body and cannot cause diseases, but pathogens can grow and reproduce in the animal body to trigger the immune response of the organism, so that the effect of obtaining long-term protection is achieved, and the effects of strong immunity and long protection time are achieved. However, the freeze-dried live vaccine is a live microbial preparation, so that the freeze-dried live vaccine has high requirements on the environment in the preservation process and has poor stability.
Fibronectin and riboflavin are added into the freeze-drying protective agent, the fibronectin is a high molecular glycoprotein and has multiple biological functions, one of the most basic functions of the fibronectin is to promote the adhesion growth of cells, and the cell adhesion is a necessary condition for maintaining the body structure and finishing the cell growth. The fibronectin has high-affinity binding sites with collagen, cells, protein and the like, the fibronectin is added into the freeze-drying protective agent, and live vaccine antigens are adhered to the fibronectin and are mutually connected through the fibronectin, so that the live vaccine antigens are protected, and the stability and the heat resistance of the freeze-dried live vaccine for animals are improved.
The riboflavin is an isoalloxazine derivative of a ribitol side chain, is an orange yellow crystal, and is dispersed in the freeze-drying protective agent, so that the adhesion of the fibronectin or the coating of the live vaccine antigen is promoted, and the protection effect of the fibronectin on the live vaccine antigen is improved.
The invention is further provided with: histidine is included in the lyoprotectant.

The invention is further provided with: the live vaccine antigen is rinderpest virus or hog cholera virus or bacillus anthracis.
By adopting the technical scheme, the rinderpest virus is a virus of morbillivirus of Paramyxoviridae, and has polymorphism and an envelope. Cattle are most susceptible to rinderpest virus, and other animals such as goats, sheep, camels, deer and pigs can also develop diseases, rinderpest is often epidemic in outbreak, and diseased cattle are the main transmission source. The classical swine fever virus is a pathogen of classical swine fever, and harms pigs and wild pigs, and other animals do not attack the swine fever virus. Hog cholera is an acute, hot and highly contagious infectious disease and is mainly characterized by high temperature and microvascular deformation causing systemic hemorrhage, necrosis and choking. The swine fever has serious harm to pigs, and can cause great loss in the pig industry. Bacillus anthracis belongs to the genus Bacillus and is responsible for some livestock.
