Question

Quizplus · Accepted Answer

Injection of antibody molecules is a form of passive immunotherapy in which pre-formed antibodies are given to an individual to immediately provide protection against a specific pathogen. This is different from immunization or vaccine therapy, which involves stimulating the body's own immune system to produce antibodies to fight off the pathogen. Serology refers to the study of antibodies in the blood, and adjuvant therapy refers to the use of additional treatments to enhance the effectiveness of a primary therapy.
