The term immunity is derived from the Latin word “immunis”,which was originally referred to the protection.
This term was adopted subsequently to designate the naturallyacquired protection against diseases, such as measles orsmallpox.
It indicated that an individual can develop lifelong resistance toa certain disease after having contracted it only once.
The cells and molecules responsible for immunity constitute theimmune system, and their collective and coordinated responseto foreign substances is called the immune response.
Introduction

Before smallpox was eradicated, it was a serious infectiousdisease caused by the variola virus. It was contagious—meaning, it spread from one person to another. People whohad smallpox had a fever and a distinctive, progressive skinrash.
Most people with smallpox recovered, but about 3 out ofevery 10 people with the disease died. Many smallpoxsurvivors have permanent scars over large areas of theirbody, especially their faces. Some are left blind.
Thanks to the success of vaccination, smallpox waseradicated, and the last natural outbreak of smallpox in theUnited States occurred in 1949.

White blood cells, which fight germs Organs and tissues of the lymph system, such as the thymus,
spleen, tonsils, lymph nodes, lymph vessels, and bonemarrow. They produce, store, and carry white blood cells.
The thymus produces progenitor(ancestor) cells, which mature into T-cells (thymus-derived cells). The bodyuses T-cells help destroy infected orcancerous cells.Skin
