This is because newborn babies have an imperfect autoimmune system, which requires immunoglobulins and other immune substances in breast milk to provide passive immunization and protection against infection. Rates of diarrhea in infants who are breastfed or fully artificially infested, especially within 6 months of age, have higher rates of mortality than breast-fed infants. As early as the end of the 19th century (1892), Paul Ehrilich interpreted this phenomenon as colostrum as a carrier
