World Immunization Week 2025, observed from 24–30 April, brings together the global health community to highlight the lifesaving power of vaccines and call for renewed commitment to immunization for all.
Under the banner Immunization for All is Humanly Possible, this year’s campaign stresses how, with collective efforts and investment, everyone can be protected from vaccine-preventable diseases.
Vaccines are one of the humanity’s greatest achievements. Over the last 50 years essential vaccines have saved 154 million lives. That’s 6 lives a minute, every day, for 5 decades. Vaccines account for 40% of the improvement in infant survival over the last half century, enabling more children than ever before to celebrate their first birthday.
Despite these significant gains, progress has stalled. In 2023, 14.5 million children worldwide, including nearly 3 million in the Eastern Mediterranean Region, didn’t receive any routine vaccine dose. Inequities, conflict, misinformation and funding gaps continue to undermine immunization efforts, leaving millions vulnerable.
