Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Gene for antigen of pathogen
Concept:

Subunit recombinant vaccine construction strategy.

Solution:

Recombinant vaccines are manufactured by isolating the gene encoding a potent immunogenic protein (antigen) of a target pathogen, cloning it into a vector, and expressing it in host bioreactors to mass-produce pure antigens.

Why other options are incorrect:

  • Gene for receptor of the patient: Cloning human host receptors does not elicit protective immune responses against foreign infectious microbes.


  • Gene for antigen of patient: Patient self-antigens induce immune self-tolerance or harmful autoimmune reactions rather than pathogen immunity.


  • Gene for antibody of patient: Cloning antibody genes produces passive antibody therapies, not active immunization vaccines.

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.
