Immunization efforts are under growing threat as misinformation, population growth, humanitarian crises, and funding cuts jeopardize progress leaving millions of children, adolescents, and adults at risk.
This warning comes from the World Health Organization (WHO), UNICEF and Gavi during World Immunization Week, which begins April 24 and ends on April 30, 2025.
Outbreaks of vaccine-preventable diseases such as measles, meningitis, and yellow fever are rising globally, and diseases like diphtheria, which have long been held at bay or virtually disappeared in many countries, are at risk of re-emerging.
In response, the agencies are calling for urgent and sustained political attention and investment to strengthen immunization programmes and protect significant progress achieved in reducing child mortality over the past 50 years.
