Infectious diseases are everywhere, but vaccines can keep us healthy. Some diseases are deadly. Epidemics can kill thousands of people.
Before vaccines, that is exactly what happened. The 1918 Spanish Flu pandemic killed an estimated 20 million to 50 million people around the world.
Diseases once feared worldwide — diphtheria, measles, polio and smallpox — are under control, and in some places eradicated, because of vaccines. Vaccines prevent an estimated 2.5 million deaths annually among children under the age of 5. But many more die because they don’t get vaccines.
The National Institute of Allergy and Infectious Diseases and the Centers for Disease Control and Prevention work in partnership with international agencies, countries and private companies to create effective vaccines to combat Ebola, HIV/AIDS, influenza and other deadly diseases and promote global health.
