World Immunization Week – celebrated in the last week of April (24 to 30 April) – aims to promote the use of vaccines to protect people of all ages against disease. Immunization saves millions of lives every year and is widely recognized as one of the world’s most successful and cost-effective health interventions. Yet, there are still nearly 20 million children in the world today who are not getting the vaccines they need.
This year's campaign will focus on how vaccines – and the people who develop, deliver and receive them – are heroes by working to protect the health of everyone, everywhere.
