Question
Which type of vaccine involves using a weakened form of the pathogen to stimulate the immune system?
Correct Answer
Option C is the correct answer.
Detailed Explanation
According to page 4, 'Live attenuated' vaccines use a weakened pathogen, such as in oral polio and measles vaccines, to stimulate the immune system without causing the full disease.
Hint
Think about the state of the pathogen in the vaccine: is it dead, alive but weak, or just a part of it?
