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 are one of humanity’s greatest achievements. Since 1974, they’ve saved 154 million lives – that’s more than 3 million lives a year or six people every minute for five decades. In the same period, vaccination has reduced infant deaths by 40%, and more children now live to see their first birthday and beyond than at any other time in human history. Measles vaccine alone accounts for 60% of those lives saved. 

More lives are now being saved, among people of all ages, with more recent vaccines against malaria, HPV, cholera, dengue, meningitis, RSV, Ebola and mpox, reflecting an era of massive scientific advancements in vaccine development and delivery.   ​ 

Every new child born deserves the benefit of these vaccines, yet millions still miss out each year.  To ensure that the immunization successes of the past 50 years are built on in the coming decades, this year’s theme, Immunization for All is Humanly Possible, aims to continue the “Humanly Possible” campaign with a future forward look on the importance of ensuring more people, especially children, are vaccinated. ​ 

As 2025 is the mid-point in the Immunization Agenda 2030, World Immunization Week will look at not only what immunization does to improve lives today but what immunization can achieve in the coming decades as more children are reached with essential immunizations and new and newer vaccines are developed to cover a broader range of diseases and ages.  

Vaccines are proof that less disease, more life is possible when we put our minds to it. In 2025, let’s show the world that ​Immunization of All is Humanly Possible.​ 

​Campaign objectives: 

To raise awareness that Immunization for all is Humanly Possible, World Immunization Week 2025 aims to:  

  • Demonstrate it is humanly possible to have less disease and more life, if people – and their communities – protect themselves and their loved ones from vaccine-preventable diseases through immunization. ​ 
  • Encourage governments to turn vaccines into vaccinations through strong immunization programmes at local and national levels to deliver on the promise of immunization for all.​
