Question

Quizplus · Accepted Answer

Live attenuated vaccine agents have several advantages, including lifelong immunity, stimulation of both cell-mediated and humoral immune responses, requiring few or no booster immunizations, and generating an immune response that closely mimics a real infection. However, their major disadvantage is that they occasionally revert to virulent forms, potentially causing disease in vaccinated individuals or spreading to unvaccinated individuals.
