Polio is an infectious disease mostly contracted by children. One in two hundred people develop incurable paralysis after infection. In 1955, a vaccine was invented and was introduced on a wide scale. Thanks to global efforts, polio was eliminated from the Western Hemisphere by 1994, and has greatly decreased worldwide.
Each year, 33000 people die from an infection due to bacteria resistant to antibiotics. The burden of infections with bacteria resistant to antibiotics on the European population is comparable to that of influenza, tuberculosis and HIV/AIDS combined.
