Solution

The correct option is C
It creates immunity in the body against the virus

Children are vaccinated because it creates immunity in the body. When the immune system first encounters an infectious microbe, it responds against it and then recognises it specifically later. So the next time that particular microbe enters the body, the immune system responds with vigour. This eliminates the infection quickly than the first time around. This is the principle of vaccination.
