Sickness
It exposes your body to a small dose of that disease which your body starts making anti bodies for. Your body then knows how to deal with that disease if it ever should come.
Vaccinations are dead cells of the disease. When it enters the body, the body 'fights' the disease without hurting the body. The body then builds up a defense system against this disease and is ready if and when the disease really happens.
All vaccinations work on the same principle. By injecting into the body a material which is chemically similar to a given disease organism (such as the tuberculosis baccilus) the immune system is activated, and will prepare an immune response to that disease before the actual disease organism ever enters the body. Therefore there is a faster and more effective immune response if the disease is ever actually encountered.
