D) toxoid
E) inactivated whole

Question

Quizplus · Accepted Answer

The preparation of the laboratory-grown microbe that is treated with a lethal dose of ionizing radiation is an example of an inactivated whole vaccine. In this type of vaccine, the pathogen is killed with a physical or chemical method, such as radiation or formalin, and then administered to the individual. The dead microbes still stimulate an immune response, but they are no longer capable of causing disease.
