Live Attenuated

What is Live Attenuated?

Live Attenuated meaning Synonym(s): AttenuatedA disease-causing virus or bacterium that is weakened in a laboratory so it cannot cause disease (or only mild disease). Live attenuated viruses are often used as vaccines because, although weakened, they can stimulate a strong immune response. However, because of remote possibility that a live attenuated virus could cause disease, people infected with HIV should not receive most live attenuated vaccines. Related Term(s): Vaccine
