Propolis Cognitive Error Autopsy

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

Snake bites require immediate neutralization of the toxin, which is too fast for the victim's immune system to mount an active response.

Formula:

None

Solution:

  • Anti-venom consists of concentrated antibodies harvested from an animal (like a horse) that has been hyperimmunized against the venom.


  • Since the antibodies are injected via syringe, it is an artificial transfer.


  • Because the victim's body is receiving pre-formed defenses rather than making its own, it is passive immunity.


Why other options are incorrect:

  • Active immunity would mean waiting weeks for the victim to produce their own antibodies, by which point the venom would have been fatal.
