A Nursing Baby

Question

A nursing baby:
A) lacks cell-mediated immunity.
B) lacks antibody-mediated immunity.
C) lacks an adaptive immune response.
D) receives active immunity via the breast milk.
E) receives passive immunity via the breast milk.

Accepted Answer

Breast milk contains antibodies, particularly IgA, which are passed from the mother to the baby, providing the baby with passive immunity. This helps protect the infant against infections during the early months of life, when the baby's own immune system is still developing.
