Attenuated Bacteria Vaccine

**Semantic type:** Chemical Viewed Functionally

**Definition:** Any vaccine created by reducing the virulence of bacteria but still keeping the bacteria viable (live). In the production of an attenuated vaccine, the infectious agent is altered so that it becomes harmless or less virulent. This is in contrast to those vaccines produced by "killing" the pathogen (inactivated vaccine).

**Synonyms:** - Attenuated Bacteria - Attenuated Live Bacterial Vaccine - Attenuated Live Bacterial Vaccine - Live Attenuated Bacterial Vaccine
