Is it true that the toxoid vaccines use a toxin produced by bacteria to stimulate an immune response?

Toxoid vaccines use a toxin, which is a harmful substance produced by certain bacteria, to stimulate an immune response. However, the toxin is treated to make it harmless, while still retaining its ability to stimulate an immune response. When a person receives a toxoid vaccine, their immune system recognizes the treated toxin as foreign and produces a response, including the production of antibodies, that will protect against future exposure to the toxin. Examples of toxoid vaccines include tetanus and diphtheria.
