In brief: Immune response

All vaccines expose the body's immune system to viral protein or an attenuated strain of the virus, neither of which cause illness.
The immune system reacts against the new protein and you become immunized by a defense cell memory of that protein which prevents infection in the future. Polio vaccine works in the same way.
