Quizplus · Accepted Answer

Active immunity results when a person has had previous exposure to a disease or pathogen, or when a person receives immunizations against a disease to stimulate the production of a specific antibody. Active immunity affords the person acquired permanent protection.
A person gains passive immunity by being given immune substances created outside that person's body for temporary immunity, such as antibodies received through the placenta, when breast milk is fed to a child, or when immune globulin, an antibody-containing preparation made from the plasma of healthy donors, is given to help a person combat disease.
