Which type of vaccine is derived from collecting the toxins produced by a pathogen?

The type of vaccine derived from collecting the toxins produced by a pathogen is known as a toxoid vaccine. These vaccines are created by inactivating the toxins produced by pathogenic bacteria so that they can no longer cause disease but still provoke an immune response. The inactivated toxins, or toxoids, stimulate the body to produce antibodies without causing the disease itself.

Toxoid vaccines are particularly effective against diseases that are caused by bacterial toxins, such as diphtheria and tetanus. By using these inactivated toxins, the immune system learns to recognize the toxins and mounts a defense if it encounters the live bacteria in the future. This method provides protection against the disease while minimizing the risk of adverse effects associated with a live pathogen.

In contrast, subunit vaccines contain specific pieces of the pathogen, rather than the whole organism or its toxins. Naked DNA vaccines use DNA from the pathogen to provoke an immune response, and killed vaccines consist of whole pathogens that have been killed or inactivated, rather than their toxins. Each of these alternatives has a different mechanism of action and scope of use.
