What is the difference between toxin and toxoid

There are two different classes of cells that comprise the adaptive immune response; they differ by the structures that give them their ability to bind antigens— the invading bacteria and viruses. Both these cells are called lymphocytes ; individually, they are the B-lymphocytes B-cells and T-lymphocytes T-cells.

Both originate from stem cells in the bone marrow; B and T refer to the place in the body where they mature. T-cells mature in the thymus into several subclasses of T-cells that circulate in the blood and lymph. B-cells mature in the bone marrow and migrate to secondary lymphoid tissues e.

After the B and T-lymphocytes react to an antigen, two results are possible. The first, and desirable result, is that the invader is identified and defeated, leaving behind what might be called its criminal record: immune memory.

When the antigen comes creeping back in the future, the adaptive immune system recognizes it and attacks. The second possibility is an over-reaction and lack of cessation of the adaptive immune process that is harmful to the body: an autoimmune condition. Where do vaccines come into this process? An antigen is a substance that causes the body to mount an immune response against it.

Vaccines have structural features similar to structures of the toxin or invading pathogen that can elicit adaptive immunity. An epitope is a specific molecular region on the surface of an antigen, typically one of many on the antigen, that elicits an immune response and is capable of binding with the specific antibody produced by the response. This is the most common and most poisonous substance which causes botulism or food poisoning. You will develop an immunity against a particular toxin if you take the corresponding toxoid.
