Understand the types of immunity: Active immunity involves the body producing its own antibodies in response to an antigen, while passive immunity involves receiving antibodies from another source.
Recognize that natural immunity occurs through natural processes, such as infection or maternal transfer, whereas artificial immunity is induced through medical interventions like vaccines or antibody injections.
Identify that breastfeeding transfers antibodies (mainly IgA) from the mother to the infant through breast milk, providing immediate but temporary protection.
Since the infant is receiving pre-formed antibodies from the mother (not producing them), this is an example of passive immunity.
Because the antibodies are transferred naturally (not through medical intervention), this is classified as natural passive immunity.
