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.

Adaptive Immune Response

The body's immune system's ability to recognize and specifically react to pathogens through the activation of lymphocytes, providing long-lasting protection.

Active Immunity

Immunity that develops as a result of exposure to antigens; it can occur naturally after recovery from a disease or can be artificially induced by immunization with a vaccine. Compare with passive immunity.

Passive Immunity

Temporary immunity that depends on the presence of immunoglobulins produced by another organism. Compare with active immunity.
