Answer 1

A live avirulent bacteria vaccine is prepared from live bacteria that have lost their virulence but retained their ability to induce protective immunity.

Step-by-step explanation:

The term that best defines live avirulent bacteria vaccine is Vaccine prepared from live bacteria that have lost their virulence but retained their ability to induce protective immunity.

Live attenuated vaccines expose an individual to a weakened strain of a pathogen with the goal of establishing a subclinical infection that will activate the adaptive immune defenses. These vaccines stimulate a comprehensive immune response and lead to long-lasting immunity.
