Immunization with the childhood DPT (diphtheria, pertussis, and tetanus) vaccine protects against subsequent exposure to tetanus by
A) stopping isotype switching of B cells from IgM to IgA.
B) preloading antigen-presenting cells.

D) producing life-spanning antitetanus IgE antibodies.
E) generating tetanus-specific memory B cells.

Question

Quizplus · Accepted Answer

Immunization with the childhood DPT vaccine generates tetanus-specific memory B cells, which provide long-term protection against future exposure to tetanus. These cells can be rapidly activated upon subsequent exposure to tetanus, leading to a quick and effective immune response.
