inactivated

Rendered no longer functional

Inactivated describes something—usually a virus, vaccine, or biological agent—that has been treated to eliminate its ability to cause disease while retaining its structure.

An inactivated vaccine uses killed pathogens to trigger immunity without risk of infection: The flu shot contains inactivated virus.

The term appears almost exclusively in medical and scientific contexts.
