An immunogen is a substance that can provoke an immune response in the body. It's essentially an antigen that triggers the immune system to produce antibodies or other immune cells. Think of it as a signal flare that alerts your body's defenses. π‘οΈ Immunogens can be bacteria, viruses, or other foreign substances. When recognized, the immune system attacks and remembers it. It's like training your body to fight back.
