Passive immunity can occur naturally, when maternal antibodies are transferred to the fetus through the placenta, and it can also be induced artificially, when high levels of antibodies specific to a pathogen or toxin (obtained from humans, horses, or other animals) are transferred to non-immune persons through blood products that contain antibodies, such as in immunoglobulin therapy or antiserumtherapy.

Example: maternal antibody igg is transferred to infant through placenta. Active immunity is the result of a patient's immune system being exposed directly to a weakened or dead form of the pathogen and reacting by developing immunity to the agent. Both natural and artificial sources of immunity can be active or passive. When germs of any disease enter our body these WBCs put up a fight. Passive Naturally Acquired Immunity . 2. B.

The thick yellowish milk (colostrum) produced for the first few days following birth is particularly rich in antibodies. Antibodies are transferred from one person to another through natural means such as in prenatal and postnatal relationships between mother and child. Some antibodies can cross the placenta and enter the fetal blood.
