In his History of the Peloponnesian War, the Greek historian Thucydides wrote that during the Plague of Athens in 430 BCE, individuals who survived the plague were able to care for the sick without risk because they were immune as a result of their recovery. This is the first recorded observation of immunity to infectious disease, but it is only in modern times that we have the tools to understand the source of that immunity.

EXPLAIN HOW the immune system protects the body from re-infection after it has cleared a pathogen. Which cell types are involved? How are those cells made, and what is special about them? What happens during the initial encounter with the pathogen? How do these events lead to protection at a later time? How is the protection maintained? Be clear and specific in your explanation.
