Anthony Komaroff, MD, Internal Medicine, answeredWith some bacterial diseases, such as diphtheria and tetanus, the problem is not the bacteria themselves but rather the toxins they produce, which enter and poison cells. Therefore, toxoid vaccines contain inactivated toxins, known as toxoids. Toxoid vaccines stimulate antibody production. When a person is infected, these antibodies can block the toxins from getting into cells.
