Since there is no transmission, the virus will not spread any further. Thus the spread of the disease can be controlled.

Immunization itself is a process when an individual’s immune system is strengthened to fight an infectious agent, such as a virus.
In the concept of Herd Immunity, to obtain population immunity, a large part of the population is immunized, thereby lowering the overall amount of virus that can spread throughout the population.
