Vaccines reduce risks of getting a disease by working with your body's natural defenses to build protection. When you get a vaccine, your immune system responds. It recognizes the invading germ, such as the virus or bacteria. It produces antibodies. Antibodies are proteins produced naturally by the immune system to fight disease. The immune system also remembers the disease and how to fight it. If you are then exposed to the germ in the future, your immune system can quickly destroy it before you become unwell. The vaccine is therefore a safe and clever way to produce an immune response in the body, without causing illness.
