Immunization Prevents Death Worldwide

Immunization is a global health and development success story, saving millions of lives every year.

Vaccines are among the greatest advances in global health and development. For over two centuries, vaccines have safely reduced the scourge of diseases like polio, measles, and smallpox, helping children grow up healthy and happy.

Thanks to immunization efforts worldwide, children are able to walk, play, dance and learn. Vaccinated children do better at school, with economic benefits that ripple across their communities. Today, vaccines are estimated to be one of the most cost-effective means of advancing global welfare. They act as a protective shield, keeping families and communities safe.
