Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Vaccination
Concept: Artificial vs. Active Immunization modalities.

Solution: Vaccination delivers killed, attenuated, or sub-unit antigens artificially to trigger an individual's immune system to actively generate memory B and T cells.

Why other options are incorrect:
  • Option A: Natural infection provides naturally acquired active immunity.

  • Option B: Transplacental transfer provides naturally acquired passive immunity.

  • Option D: Antitoxin injections provide artificially acquired passive immunity.
