• Toxoid — A bacterial toxin modified through thermal and chemical treatment, usually with formaldehyde, which completely loses its pathogenic toxic power while retaining its structural antigenic properties intact. This biological substance is widely used in vaccine preparation to stimulate the body to produce specific antibodies and ensure long-lasting active immunity against severe diseases such as tetanus or diphtheria.
• Anavaccine — An immunizing biological preparation (vaccine) composed of a purified and absorbed toxoid, used to stimulate the production of specific antibodies in the organism without triggering symptoms of the disease. This structural type of vaccine retains its antigenic capacity intact while completely losing its initial pathogenicity and toxic power through controlled chemical or thermal treatment.
