Question

multiple choice question
what is artificial active immunity?

• receiving another persons antibodies against a naturally acquired pathogen
• receiving another persons or animals antibodies against a pathogen
• acquiring ones own immunity against an attenuated pathogen
• acquiring ones own immunity against a naturally acquired pathogen

Explanation:

To determine artificial active immunity, recall:

• Artificial active immunity involves stimulating the immune system (e.g., via vaccines with attenuated/weakened pathogens) to produce its own antibodies.
• "Receiving another’s antibodies" is passive immunity (artificial or natural).
• "Naturally acquired pathogen" refers to natural immunity.

Analyze options:

1. "Receiving another person’s antibodies..." → Passive immunity (not active). Eliminate.
2. "Receiving another person’s or animal’s antibodies..." → Passive immunity (e.g., antisera). Eliminate.
3. "Acquiring one’s own immunity against an attenuated pathogen" → Matches artificial active (vaccines use attenuated pathogens to trigger self-immunity).
4. "Acquiring one’s own immunity against a naturally acquired pathogen" → Natural active immunity (e.g., getting sick and recovering). Eliminate.

Answer:

C. Acquiring one's own immunity against an attenuated pathogen
