Increases in vaccine-preventable disease outbreaks threaten years of progress, warn WHO, UNICEF, Gavi
Agencies call for sustained investments in immunization efforts amidst looming funding cuts
GENEVA/NEW YORK, 24 April 2025 – Immunization efforts are under growing threat as misinformation, population growth, humanitarian crises, and funding cuts jeopardize progress and leave millions of children, adolescents, and adults at risk, warn WHO, UNICEF, and Gavi during World Immunization Week, 24-30 April.
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.
“Vaccines have saved more than 150 million lives over the past five decades,” said WHO Director-General, Dr Tedros Adhanom Ghebreyesus. “Funding cuts to global health have put these hard-won gains in jeopardy. Outbreaks of vaccine-preventable diseases are increasing around the world, putting lives at risk and exposing countries to increased costs in treating diseases and responding to outbreaks. Countries with limited resources must invest in the highest-impact interventions – and that includes vaccines.”
Gavi’s upcoming high-level pledging summit taking place on 25 June 2025 seeks to raise at least US$ 9 billion from our donors to fund our ambitious strategy to protect 500 million children, saving at least 8 million lives from 2026–2030.
