Which type of adaptive immunity is induced by vaccination?

Vaccination activates the adaptive immune system by introducing antigenic material in a controlled way, so the body’s B and T cells respond and form memory. This is artificially acquired active immunity: the exposure is intentional, the body actively generates its own immune response, and memory cells are produced for long-term protection. Naturally acquired active would come from actually fighting a real infection; naturally acquired passive involves receiving antibodies from another source (like a mother or antibody treatment) without the body making its own memory, and artificially acquired passive is giving ready-made antibodies without the host mounting a response. So vaccination fits best as artificially acquired active immunity.
