PATHOLOGY

Detailed explanation-1: -This type of immunity is called passive immunity because the baby has been given antibodies rather than making them itself. Antibodies are special proteins the immune system produces to help protect the body against bacteria and viruses.

Detailed explanation-2: -Natural passive immunity can also be transferred through breast milk. Natural passive immunity is short-lived after the birth of the child.

Detailed explanation-3: -A passive immunity acquired by the fetus or newborn from the mother via the placental transfer of antibodies during pregnancy and via breast milk. This type of immunity is short-lived, lasting the first six months of the newborn’s life.

Detailed explanation-4: -A specific type of antibody found in breastmilk, IgA, protects infants from infections. When breast milk coats the baby’s oral mucosa, nasal cavity, Eustachian tubes, and GI tract, the IgA binds to bacteria and viruses at that surface preventing them from entering the baby’s system.
