I'm a bit confused about this question. But I will try my best to answer. :)

To prevent a certain virus, or increase someone's immunity towards a virus, doctors give patients a shot/vaccine. For example, people get a flu shot yearly to help prevent them from getting the flu.

This also helps the body become more immune to the virus/sickness and fight it off easier.
