PATHOLOGY

Detailed explanation-1: -Breast milk also contains antibodies, which means that babies who are breastfed have passive immunity for longer. The thick yellowish milk (colostrum) produced for the first few days following birth is particularly rich in antibodies.

Detailed explanation-2: -Natural passive immunity involves the fetus or newborn receiving antibodies from the mother. Natural passive immunity can occur when the mother passes antibodies to the baby via placental transfer. A baby may also receive antibodies through colostrum found in the mother’s milk.

Detailed explanation-3: -Passive immunity can occur naturally, such as when an infant receives a mother’s antibodies through the placenta or breast milk, or artificially, such as when a person receives antibodies in the form of an injection (gamma globulin injection).
