Artificially acquired active immunity is defined as?

Explanation:
Artificially acquired active immunity occurs when a vaccine triggers your own immune system to respond. The immune system recognizes the vaccine antigens, produces specific antibodies, and forms memory B and T cells. This memory means you’re protected long-term and respond more rapidly if you encounter the real pathogen later. It’s generated by the host’s own response to the vaccine, unlike receiving pre-formed antibodies from someone else, which is artificial passive immunity. Protection isn’t immediate, because the immune system needs time to develop the response, but the resulting memory provides lasting protection.
