Over the last 50 years, essential vaccines have saved at least 154 million lives and increased infant survival by 40%. However, hard-won gains in stamping out diseases that are preventable through vaccination are in jeopardy. Outbreaks of vaccine-preventable diseases such as measles, meningitis, and yellow fever are rising globally.
In response, WHO, UNICEF and Gavi, the Vaccine Alliance are calling for urgent and sustained investment to strengthen immunization systems programmes and protect significant progress achieved in reducing child mortality over the past 50 years.
Under the banner, ‘Immunization for All is Humanly Possible’, World Immunization Week 2025 aims to ensure even more children, adolescents, adults – and their communities – are protected against vaccine-preventable diseases.
