World Immunization Week 2025 - 24 to 30 April
World Immunization Week, celebrated in the last week of April, aims to promote the life-saving power of immunization to protect people of all ages against vaccine-preventable diseases.
Vaccines have long been one of the most powerful tools in public health. Over the last 50 years, vaccines have saved more than 150 million lives – not by accident, but because ordinary people made the decision to protect themselves, their children and one another. That’s 6 lives every minute, every day, for five decades.
Health workers rolling up sleeves, parents bringing their children to health clinics, communities showing up, and generations deciding that preventing infectious diseases, such as measles, diphtheria, pertussis and polio, is worth it.
Those choices to vaccinate have contributed to a 40% improvement in infant survival during that time and protected tens of millions of children from lifelong disabilities. More children now live to see their first birthday – and grow up, fall in love, have families, and grow old – than at any other point in human history.
This year’s World Immunization Week theme, “For every generation, vaccines work”, aims to promote how vaccines have safely protected people, families, and communities for generations – and continue to safeguard our future.
Campaign objectives:
To raise awareness that vaccines have protected people for generations, World Immunization Week 2026 aims to:
• Demonstrate how immunization has safely and effectively protected generations from deadly diseases, thanks to the decisions individuals and families have made to protect themselves and others.
• Equip health workers with the skills and tools to communicate clearly and compassionately about vaccines, helping families who are hesitant or have questions feel informed, heard, and confident in their immunization decisions.
• Strengthen public understanding of the science behind vaccine safety and effectiveness enabling individuals, families, and communities to make informed immunization decisions.
• Reinforce trust by highlighting transparency, accountability, and ongoing innovation in immunization, and emphasize the shared responsibility to protect future generations through continued investment, research, and equitable access to vaccines.
As the global immunization community reaches the halfway point of the Immunization Agenda 2030 (IA2030), now is the time to act. By building trust, sharing accurate information, and strengthening confidence in vaccines, we can help families make informed, life-saving choices for themselves, their children and for the generations that follow.
