When medical researchers learned how to prevent disease and stop it from spreading， thequality of life for many people around the world improved. Today smallpox is a forgottendisease and vaccinations are no longer required. Polio is under control and the vaccine iswidely available . The development of penicillin has helped many people recover from seriousillness.
