Artificially acquired active immunity occurs when

• A. Vaccination and your body makes antibodies
• B. When your body makes antibodies
• C. Antibodies are from mother to fetus
• D. Injecting antibiotics

Answer: (A)

Artificially acquired active immunity happens when vaccination prompts your immune system to produce antibodies and immune memory. A vaccine introduces a safe form of an antigen, enough to activate B cells and helper T cells, triggering the production of specific antibodies and memory cells without causing disease. This is different from natural active immunity, which occurs when the body encounters a pathogen and makes antibodies in response to infection. It’s also different from passive immunity, where antibodies are transferred from another source, such as mother to fetus, without your immune system actively responding. Antibiotics don’t induce immune memory; they treat infections but don’t teach your immune system to remember pathogens. So vaccination leading to antibody production is the description that fits artificially acquired active immunity.
