Question

gabrielle was scheduled to have her first set of vaccinations yesterday. which type of immunity did she acquire?
multiple choice
artificial active
natural active
innate
artificial passive
natural passive

Explanation:

Vaccinations introduce antigens (like weakened or inactivated pathogens) into the body. The body's immune system then actively responds by producing antibodies and memory cells. Since this is a man - made (artificial) process to stimulate the immune system (active response), it is artificial active immunity.

• Artificial active: Correct as vaccinations are a man - made way to induce an active immune response (antibody and memory cell production).
• Natural active: Incorrect. Natural active immunity occurs when a person gets infected naturally (e.g., actually getting a disease) and the immune system responds.
• Innate: Incorrect. Innate immunity is the body's first - line, non - specific defense (e.g., skin, macrophages) and is not related to vaccinations.
• Artificial passive: Incorrect. Artificial passive immunity involves giving pre - formed antibodies (e.g., in some post - exposure treatments like rabies immunoglobulin), not stimulating the body to make its own antibodies.
• Natural passive: Incorrect. Natural passive immunity is when antibodies are transferred naturally, like from mother to fetus via placenta or through breast milk.

Answer:

Artificial active
