Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Babies receiving MMR shorts
Concept:

Artificial active immunity involves the medical administration of an antigen to stimulate a permanent immune response.

Formula:

None

Solution:

  • Artificial: The immune system is stimulated via a clinical injection (a shot/vaccine), rather than a natural environmental encounter.


  • Active: The MMR (Measles, Mumps, Rubella) vaccine contains attenuated viruses. The baby's immune system must actively process these and generate its own memory cells.


  • Therefore, babies receiving MMR shots is the perfect example of artificial active immunity.


Why other options are incorrect:

  • Foetus receiving antibodies: Natural passive immunity.


  • Previous infection: Natural active immunity.

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.
