If you used a full active virus, that defeats the point of a vaccine. You will trigger your immune response, but since you would just be injecting the virus, it will make you sick, and your body will be less effective at fighting the pathogens.

Injecting a virus that is not weak will just be the same thing as if you got the virus, you will likely get sick.
