Description

technical field

[0001] The invention relates to an improved protective agent for making freeze-dried live vaccines for animals, which belongs to the technical field of medical products. Background technique

[0002] Freeze-dried live vaccines for animals are a powerful weapon to control animal virus or bacterial infection. Storing freeze-dried live vaccines at room temperature can not only greatly reduce production costs, but also provide convenience for the transportation, storage and use of such products. In addition, it It can also reduce the on-site application loss rate of the vaccine, thereby increasing the effective immune protection rate of the vaccine unit. Freeze-dried live vaccines often cause a large amount of vaccine inactivation during the production process, so it is necessary to add protective agents for protection. At present, the main components of commonly used protective agents for veterinary biological products are skim milk, sucrose and gelatin, which ...
