Question

what is the reason for using weakened or dead pathogens and not live pathogens in immunizations?
a it will not get the patient sick.
b it will cause passive immunity.
c it will result in temporary protection.

Explanation:

• Option a: Weakened or dead pathogens can't cause the full - blown disease as live pathogens would, so they won't get the patient sick. This is the main reason for using them in immunizations.
• Option b: Weakened or dead pathogens induce active immunity (by stimulating the body to produce its own antibodies), not passive immunity (where antibodies are given from an external source).
• Option c: Weakened or dead pathogens in vaccines usually result in long - term protection as the body develops memory cells, not temporary protection.

Answer:

a. It will not get the patient sick.
