What is the Name of the Toxin That Has Been

Question

What is the name of the toxin that has been altered so that it is harmless yet still antigenic?
A) Vaccine
B) Antibody
C) Gamma globulin
D) Toxoid

Accepted Answer

Toxoid is a toxin that has been modified to remove its harmful effects while still maintaining its ability to induce an immune response. This allows the body to develop immunity to the toxin without being exposed to its harmful effects. Vaccines often use toxoids as a component to stimulate a protective immune response. Antibodies and gamma globulin are not toxins and do not involve modification of toxins.
