World Immunization Week, 24-30 April 2026

Vaccines have shaped healthier lives for generations and remain among the most powerful and life-saving tools in public health. Over the past 50 years, vaccines have saved more than 150 million lives — not by chance, but because millions of people chose to protect themselves, their children, and their communities from diseases such as measles, diphtheria, pertussis, polio, and rotavirus.

Today, vaccines continue to make a difference at every stage of life. Newer vaccines against malaria, HPV, cholera, dengue, meningitis, RSV, Ebola and mpox are saving lives and helping people everywhere live longer, healthier lives — thanks to scientific progress and global collaboration people of all ages can live longer, healthier lives than ever before.

During World Immunization Week, we celebrate a legacy worth passing on and a powerful truth – “For every generation, vaccines work”. Under this theme, we will highlight how vaccines have safely protected families and communities for decades — and how they continue to safeguard our shared future.

By building trust, sharing accurate information, and strengthening confidence in vaccines, we can support people everywhere to make informed decisions — protecting themselves, their loved ones, and generations to come.

Join us during World Immunization Week, 24–30 April 2026, in recognizing the generations protected by vaccines, in passing this protection forward and celebrating the power of vaccines to protect every generation.
