Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Natural passive immunity
Concept:

Maternal antibody transfer is an evolutionary mechanism to protect neonates before their own immune system fully boots up.

Formula:

None

Solution:

  • Colostrum, the first breast milk produced, is incredibly rich in secretory IgA antibodies.


  • Because breastfeeding is a standard biological process, the transfer is natural.


  • Because the baby is merely absorbing these pre-made antibodies without utilizing its own immune machinery to create them, the immunity is passive.


Why other options are incorrect:

  • Active immunity would require the baby to be infected with a disease or injected with a vaccine.
