Question

Quizplus · Accepted Answer

The toxin that has been altered so that it is harmless yet still antigenic is called a toxoid. This is achieved by subjecting the toxin to heat, chemicals or radiation to remove its toxic properties while retaining its antigenicity. The resulting toxoid can then be used as a vaccine to stimulate the immune system to produce antibodies against the actual toxin, providing immunity against future exposure. Antibodies (choice B) and gamma globulin (choice C) are not toxins and do not involve altering a toxin. Vaccines (choice A) are preparations that contain antigens, including toxoids, to provide protection against infectious diseases.
