World Immunization Week, celebrated in the last week of April, aims to highlight the collective action needed to protect people from vaccine-preventable diseases.

The goal of World Immunization Week is for more children, adults – and their communities – to be protected from vaccine-preventable diseases, allowing them to live happier, healthier lives.  

This year World Immunization Week will celebrate 50 years of the Essential Programme on Immunization (EPI).
