World Immunization Week 2026: Uniting for Universal Vaccine Coverage
World Immunization Week, observed annually during the last week of April, serves as a pivotal time for promoting vaccines' critical role in safeguarding health and wellbeing across all ages.

Spearheaded by the World Health Organization (WHO), World Immunization Week mobilizes nations, healthcare professionals, and communities worldwide, emphasizing the life-saving power of vaccines.
The Genesis of World Immunization Week
World Immunization Week's establishment reflects a global consensus on the importance of vaccines in public health. It builds on decades of immunization efforts that have successfully reduced the burden of infectious diseases, some to the brink of eradication. By coordinating with countries globally, WHO aims not only to raise awareness but also to ensure the implementation of high-quality immunization programs. This week-long observance is a key component of WHO's mission to promote health, keep the world safe, and serve the vulnerable.
Global Impact and Objectives
