natural immunity

Natural immunity is the body's built-in defense mechanism that develops after you are exposed to a disease-causing organism, such as a virus or bacteria. When this happens, your immune system recognizes the invader and creates specific defenses, like antibodies, to fight it. If you're exposed to the same germ again, your body can respond faster and more effectively, often preventing illness or reducing its severity. Natural immunity varies between individuals and depends on factors like the strength of the immune response and previous exposures. It plays a crucial role in protecting you and helps build long-term immune memory.
