serum therapy

Serum therapy is a medical treatment that involves using blood serum, which contains antibodies, to help the body fight infections. It was developed before modern vaccines and works by transferring immunity from someone who has recovered from a disease to a patient needing protection. The antibodies in the serum recognize and neutralize specific pathogens, providing temporary defense. This method is used for certain diseases like rabies or tetanus, especially when immediate immunity is needed or vaccines are not available. Serum therapy leverages the body's natural defense mechanisms to help prevent or treat infections effectively.
