Quizplus · Accepted Answer

Inactivated immunizing agents are prepared by treatment with formalin, which is a type of solution that helps kill bacteria and viruses while preserving their shape, making them suitable for use in vaccines. Alcohol and phenol are also used as disinfectants, but they are not typically used in the preparation of vaccines. Histamine, on the other hand, is a chemical mediator that is involved in allergic reactions and has no role in the production of vaccines.
