Answer:
Natural active- Antibodies are formed in the presence of active infection in the body.
Natural passive- Antibodies are transferred naturally from an immune mother to her baby through the placenta or in colostrum
Artificial active- Antigens (vaccines or toxoids) are administered to stimulate antibody production.
Artificial passive- Immune serum (antibody) from an animal or another human is injected.
Natural. Artificial. Active. Passive.
