What is Immunization?
Immunization is a term that refers to the generation of immunity. This involves ensuring that a person is not susceptible to a foreign substance such as a virus or the venom of an animal. A distinction is made between active- and passive-immunization. Active immunization aims to trigger the human body’s immune system to make antibodies and memory cells. For this, a vaccine containing a low dose of a pathogen is injected. In this way, a specific defense is generated. In passive immunization, a serum is injected. This serum is already an antibody to protect the body from a foreign substance such as the venom of an animal. Passive immunization is an application in emergency situations. The human body’s immune system is not triggered in this process.
