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: -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-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).

Detailed explanation-4: -Mothers convey passive immunity to their newborns through the transplacental transfer of antibodies, hereby providing a shield for the infant from pathogen-mediated diseases (1, 9). The amount of transferred antibodies can differ between individuals and is mainly dependent on maternal antibody concentrations (10, 11).
