World Immunization Week, observed annually during the last week of April, is a global initiative led by the World Health Organization (WHO) to strengthen vaccine awareness and promote equitable access to immunization for people of all ages, everywhere.
This essential campaign underscores the life-saving impact of vaccines in preventing diseases such as polio, measles, and diphtheria. Despite significant progress, millions of children around the world still lack access to essential vaccinations, placing them at risk of preventable illnesses.
Vaccines are one of the most cost-effective and impactful health interventions ever developed. They not only protect individuals but also help build herd immunity, protecting entire communities—especially the most vulnerable.
