MICROANATOMY

Detailed explanation-1: -A type of immunity that occurs when a person is given antibodies rather than making them through his or her own immune system. For example, passive immunity occurs when a baby receives a mother’s antibodies through the placenta or breast milk.

Detailed explanation-2: -Passive immunity is naturally transferred to breast fed babies from their mother’s milk. Breast milk has colostrum that contains antibodies against pathogens the mother has been exposed to. Transfer of antibodies that occurs from mother to foetus via the placenta is also an example here.

Detailed explanation-3: -Give a few examples of active and passive immunity. Immunization of chickenpox, hepatitis, flu, and polio are some examples of active immunity. A baby receiving antibodies from her mother’s breast milk and injection of antisera are examples of passive immunity.
