Toxoid

Toxoids are proteins in certain bacteria and viruses that have been modified in order to make them safe for use as vaccines. When injected, toxoids cause the body to develop antibodies that protect it from the disease caused by the bacterium or virus they are derived from. Toxoids are used in a variety of vaccines, including those for diphtheria, tetanus, and pertussis - all three of which are part of the recommended childhood immunization schedule. The use of toxoids in vaccines is an effective and safe way to protect against many dangerous and potentially life-threatening diseases.
