World Immunization Week, April 24-30 2026

Global public health awareness days aim to increase visibility, awareness and understanding of specific diseases or health conditions among the general public. They are key in highlighting the importance of healthy lifestyles and well-being among the general population. Each year, various organizations and communities around the world actively participate in promoting and supporting World Health Days.

Celebrated annually during the last week of April, World Immunization Week highlights the importance of vaccination to protect individuals and communities against disease.  The goal is to increase public awareness regarding the value of vaccines and to ensure that people of all ages have access to effective immunization programs. Since their creation, vaccines have been a critical public health tool, saving more than 150 million lives in the past 50 years. This event emphasizes that consistent vaccination efforts continue to safeguard public health across generations. This year’s theme is “For every generation, vaccines work”.
