Formulations used for artificial passive immunization, collectively referred to as immune sera, include antibacterial serum, antiviral serum, and antitoxins. After the animal is infected with the pathogen, the use of immune serum means that the antibody is directly input into the animal, which can quickly kill the pathogen or neutralize the toxin, promote the rapid recovery of the body, and play a good therapeutic role. Clinically, the following questions should be noted when using immune serum: Early use of immune sera can kill pathogens or neutralize toxins, but this effect is limited to pathogens and exotoxins that are not bound to tissue cells, and cannot act at all on pathogens and toxins that have caused tissue damage. Therefore, the sooner you use immune serum to treat infectious diseases, the better. The use of a reasonable immune serum, most of the use of injection, but in the injection method, can be injected subcutaneously, but also intravenous injection. In general, subcutaneous injections are often used because intravenous absorption is the fastest, but it is prone to cause allergic reactions. It is mainly used during prophylaxis. The dosage is sufficient to treat infectious diseases with immune serum. Effective immediately after injection, the effect is good, fast, but because it is a serum product, the half-life is short. The serum of the same animal has a half-life of 3 weeks. The serum of heterologous animals has a half-life of only 2 weeks. The effective maintenance period of serum is generally only 2 to 3 weeks. Therefore, multiple injections and injections must be given in order to achieve the desired results. To prevent the onset of immune sera, horse and cow blood preparations are often used. Horse and bovine serum are also antigenic to other animals and may cause serum disease. Therefore, the use of immune sera should be prevented to prevent serum disease. The main measures for prevention are: The use of purified products does not require unqualified products; in addition, do not have the idea of ​​quick success and instant benefit.
