Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Artificial active immunity
Concept:

Vaccines simulate an infection to trick the immune system into developing immunological memory.

Formula:

None

Solution:

  • Because a vaccine is deliberately and medically introduced into the body, it is an artificial process.


  • Because the vaccine contains antigens that force the host's own immune system to actively generate antibodies and memory cells, it provides active immunity.


  • Therefore, vaccination equals artificial active immunity.


Why other options are incorrect:

  • Natural active: Getting sick from the wild pathogen.


  • Artificial passive: Receiving an injection of pre-made antivenom.
