Vedclass · Answer

(A) An attenuated virus is a weakened form of a virus that has been modified in a laboratory setting to reduce its virulence (pathogenicity).Because it is weakened,it does not cause the disease in a healthy individual but is still capable of replicating and stimulating the immune system.This property makes attenuated viruses highly effective as vaccines,as they trigger a strong,long-lasting immune response without causing the actual infection.Therefore,the correct description is that it is a virus that is non-pathogenic.
