Detailed explanation-1: -This type of immunity is called passive immunity because the baby has been given antibodies rather than making them itself.
Detailed explanation-2: -Breast milk shares antibodies from the mother with her baby. These antibodies help babies develop a strong immune system and protect them from illnesses.
Detailed explanation-3: -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.
Detailed explanation-4: -A large part of immunoglobulins excreted in milk are IgA that protect mainly against enteric infections. The specificity of maternal milk IgA is driven by an entero-mammary cell circulation. Human milk also contains anti-idiotypic antibodies capable of enhancing infant antibody response.
