immune system adaptation

The immune system adapts by learning to recognize and target specific threats like bacteria, viruses, or other harmful agents. When exposed to a pathogen, it develops memory cells that remember how to fight it in the future. This process allows the immune system to respond more quickly and effectively upon subsequent encounters. Essentially, it fine-tunes its defenses over time, becoming better at protecting the body against infections, much like how experience improves performance. This adaptation is the basis for immunity gained from infections or vaccines.
