Passive immunity occurs when 'preformed' antibodies are made in one animal and passed onto another. For example a cow passes on her own antibodies to her calf via colostrum (first milk after parturition) and milk.

Antibodies can be transferred to other individuals via colostrum, milk, crossing of the [[Gestation -Placenta - Anatomy & Physiology|placenta]], [[Vaccines|vaccination]], and plasma transfusions.
