Question

The type of immunological protection provided by plasma therapy is

• A. Natural active
• B. Natural passive
• C. Artificial active
• D. Artificial passive

Hint:

{Active immunity:} Your body produces antibodies. {Passive immunity:} You receive ready-made antibodies. Plasma therapy = Artificial + Passive.

Answer 1

The Correct Option is D

Step 1: Recall the concept of plasma therapy.
In plasma therapy, antibodies from the blood plasma of recovered individuals are injected into a patient to provide immediate immunity.
Step 2: Classify the type of immunity.
This immunity is passive because the recipient receives ready-made antibodies rather than producing them through their own immune response.
It is artificial because it is induced by medical intervention, not natural exposure.
Step 3: Conclusion.
Hence, plasma therapy represents artificial passive immunity.
