Doctors do not administer vaccinations to people who are too sick. Which best explains why?
4vir4ik [10]

Answer:

D, The white blood cells of sick people may not be able to efficiently handle the weakened or dead form of the pathogen.

Explanation:

  • Why not C: The digestive system isn't the issue. You don't eat diseases.
