Vaccination is the introduction of weakened microorganisms into the body. When they are introduced into the human body, an immune reaction begins: microorganisms are foreign bodies, antibodies begin to be produced against them, which quickly destroy weakened microorganisms. With the subsequent ingress of such microorganisms into the human body, ready-made antibodies are in the human body.
Serum differs from vaccination in that it contains ready-made antibodies, the body does not have to produce them itself.
