The transfer of antibodies from mother's milk to the baby is called:

Appeared in: GMCH - 2016

Explanation

The transfer of antibodies from mother to baby via breast milk is a natural biological process.
The baby receives ready-made antibodies (primarily IgA) and does not produce them, making the immunity 'passive'.
This process provides immediate, though temporary, protection against various pathogens the mother has been exposed to.
It is a key reason why breastfeeding is recommended, especially in the early months of life.

Option A: This is incorrect because the immunity is acquired naturally through breastfeeding, not artificially through a medical procedure like an injection.
Option B: This is incorrect for two reasons: the process is natural, not artificial, and the immunity is passive, not active. The baby's immune system is not stimulated to produce its own antibodies.
Option D: This is incorrect because the immunity is passive. The baby is receiving antibodies, not actively producing them in response to an infection.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Types of Acquired Immunity as background academic context rather than a clinical decision trigger.
Nurses play a vital role in educating new mothers about the immunological benefits of breastfeeding, as colostrum and breast milk are rich in antibodies that protect newborns.
Understanding the different types of immunity is fundamental for nurses to explain vaccination schedules (artificial active immunity) and treatments like immunoglobulin therapy (artificial passive immunity) to patients and their families.
What if? If an infant is formula-fed, they do not receive this natural passive immunity from breast milk. This makes strict adherence to the recommended vaccination schedule even more critical to protect them from preventable diseases as they develop their own active immunity.

How to Approach the Question

First, identify the key phrases in the question: 'transfer of antibodies' and 'from mother's milk'.
Analyze the source of immunity: 'Mother's milk' is a natural process, not an artificial one like a vaccine or injection. This helps eliminate the 'artificially acquired' options.
Analyze the mechanism of immunity: 'Transfer of antibodies' means the baby is receiving them ready-made. This is a passive process, as the baby's own immune system is not actively creating the antibodies.
Combine the two analyses: The process is both 'natural' and 'passive'.
Scan the options to find the one that matches this description: 'Naturally acquired passive immunity'.
