Concept:Recombinant DNA technology in vaccine development allows isolation and recombinant synthesis of specific antigenic surface proteins of complex pathogens.
Solution:Biotechnology allows scientists to produce recombinant subunit vaccines containing isolated surface antigens of the
Plasmodium parasite. This enables the human immune system to produce a highly targeted, protective humoral and cellular immune response without exposure to live or whole virulent pathogens.
Why other options are incorrect:- Its ability to work as antimalarial drugs: Vaccines confer prophylactic immunity; they do not act directly as chemical antimalarial therapeutic drugs (such as artemisinin or chloroquine).
- Its ability to directly kills the malaria parasite in mosquitoes: Vaccines function within the human host immune system, not as direct insecticides or antiparasitic agents inside vector mosquitoes.
- Its ability to develop endosymbiotic relationship with host: Vaccines do not establish symbiotic relationships; they train the adaptive immune system to destroy pathogens.
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.
