Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Artificial passive immunity
Concept: Classifications of artificial acquired immunity.

Solution: Anti-venom provides immediate neutralising protection by injecting pre-formed hyperimmune antibodies (produced externally in another host or lab). Because it is artificially administered and provides transient protection without activating host memory cells, it is classified as artificial passive immunity.

Why other options are incorrect:
  • Option A: Requires natural exposure and active memory creation.

  • Option B: Involves natural antibody transfer, such as transplacental maternal transfer.

  • Option D: Involves active memory development following vaccination.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
