A nurse is teaching an expectant mother about breastfeeding versus formula feeding. Which statement best describes a specific immunological advantage of breastfeeding for the infant?

• A. Provides complete nutrition for the first year
• B. Has no immunological benefit
• C. Antibodies transferred from mother through breast milk
• D. Reduces the risk of post-term pregnancy

Answer: (C)

Maternal antibodies in breast milk provide a passive immunological shield for the infant. The milk contains antibodies, especially secretory IgA, that line the infant’s gut and other mucosal surfaces. This helps neutralize pathogens and reduces the likelihood of infections in early life when the baby’s own immune system is still maturing. In addition, components like lactoferrin, lysozyme, and bioactive oligosaccharides support immune defense and healthy gut microbiota, further boosting protection against illness.

So the statement that best describes a specific immunological advantage is that antibodies are transferred from mother through breast milk, giving the newborn real, early protection. The other options miss this immunological aspect or address unrelated issues—breast milk isn’t guaranteed to provide complete nutrition for a full year, there is indeed an immunological benefit, and reducing the risk of post-term pregnancy pertains to maternal pregnancy timing rather than infant immunity.
