The body’s immune system is stimulated to develop antibodies to a particular antigen.
Immunity which is acquired by catching and surviving an infectious disease or by vaccination with a weakened form of the disease, which makes the body form antibodies.
Form of acquired immunity in which the body produces its own antibodies against disease-causing antigens. It can occur naturally after infection or artificially after vaccination.
Immunity resulting from the development within the body of antibodies or sensitized T lymphocytes that neutralize or destroy the infective agent. This may result from the immune response to an invading organism or from inoculation with a vaccine containing a foreign antigen.
Immunity that is created by a person’s own immune system as the result of having a disease or receiving a vaccine.
Immunity developed as a result of recovering from an infection.
Immunity obtained through the introduction of a small amount of germ toxin or inactivated germs into the patient’s body. The body’s immediate response mimics the reaction to a real germ invasion by producing germ-specific antibodies. These antibodies remain in the bloodstream, so if the actual germ enters the body at a later time, it is promptly neutralized by the circulating antibodies.
