A vaccination is the injection of a killed or weakened organism that produces immunity in the body against that organism. An immunization is the process by which a person or animal becomes protected from a disease. A vaccine is a biological preparation that provides active acquired immunity to a disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins. The administration of vaccines is called vaccination. Vaccination is the most effective method of preventing infectious diseases; widespread immunity due to vaccination is largely responsible for the worldwide eradication of smallpox and the restriction of diseases such as polio, measles, and tetanus from much of the world.
