The aim of World Immunization Week is to promote the use of vaccines to protect people of all ages against disease. The week takes place from 24-30 April. Every year, millions of lives are saved thanks to immunization and it is recognized widely as one of the most successful and cost effective health interventions. However, nearly 20 million children are still unvaccinated and under-vaccinated worldwide.
With the theme #VaccinesWork for All, the campaign focuses on how vaccines as well as the people who develop, deliver and receive them are vaccine champions by working to protect the health of everyone, everywhere.
As part of the 2020 campaign, WHO and partners aim to:
- Demonstrate the value of vaccines for the health of children, communities and the world.
- Show how routine immunization is the foundation for strong, resilient health systems and universal health coverage.
- Highlight the need to build on immunization progress while addressing gaps, including through increased investment in vaccines and immunization.
