As the world marks World Immunization Week in the last week of April, the focus remains on harnessing the power of vaccines to protect people of all ages from preventable diseases. This year’s theme, “Immunization for All is Humanly Possible,” reinforces the global commitment to ensuring that vaccines reach every child and adult, safeguarding public health for future generations.

The Lifesaving Impact of Vaccines

Since 1974, vaccines have saved an estimated 154 million lives, averaging over 3 million lives each year—or six people every minute. In that time, infant mortality rates have declined by 40%, allowing more children to celebrate their first birthdays than ever before. The measles vaccine alone accounts for 60% of the lives saved through immunization efforts.

Scientific advancements have led to the development of newer vaccines against malaria, HPV, cholera, dengue, meningitis, RSV, Ebola, and mpox, further expanding the protection available across all age groups.

Bridging the Immunization Gap

Despite these successes, millions of children worldwide still miss out on essential vaccines every year. World Immunization Week 2025 serves as a reminder of the urgent need to close this gap and strengthen global immunization efforts.

As 2025 marks the midpoint of the Immunization Agenda 2030 (IA2030), this year’s campaign will highlight not only the current impact of immunization but also its potential in the coming decades. With continued innovation and expanded access, newer vaccines will help combat a broader range of diseases, ensuring healthier lives for generations to come.

By reinforcing immunization programs and increasing global vaccine equity, the world can build on 50 years of progress and move closer to a future where preventable diseases no longer pose a threat to human health.
