Question

Quizplus · Accepted Answer

This is an example of natural active immunity because the person's immune system responded to the actual mumps virus and developed a memory of how to fight it off if exposed again in the future. Artificial active immunity would occur if the person received a vaccine containing a weakened or inactivated form of the mumps virus to stimulate their immune system to produce protection against the virus.
