Vaccines save millions of lives

Gavi, the Vaccine Alliance, and Save the Children partner to strengthen global immunisation, focusing on reaching children who have never received a vaccine (‘zero-dose' children) in conflict zones and hard-to-reach communities. Our partnership protects children against preventable diseases.  

Save the Children and Gavi’s partnership has grown significantly in recent years, and cuts across advocacy for resource mobilization, thought leadership, policy and programmes. We will continue to collaborate around our common goals of reaching zero-dose and under-immunised children and strengthening national immunisation programmes and health systems.  

Established in 2000, Gavi works to ensure that vaccines are available to children and communities around the world, particularly in countries that lack the resources to purchase vaccines or deliver vaccination services. Their work aligning closely with Save the Children’s Ambition for Children 2030 to ensure that no child dies from preventable causes before their fifth birthday.   

Key facts: 

  • More than 50% of zero-dose children live in fragile, vulnerable and conflict-affected contexts.
  • To date, Gavi has vaccinated more than 1.1 billion children worldwide and saved 18.8 million lives.
  • A child born in a Gavi supported country is 70% less likely to die from a vaccine-preventable disease before their 5th birthday than they were when the Alliance began.
  • Each $1 spent on immunisation brings $54 in wider economic benefits.

Our Impact: providing lifesaving vaccines in Sudan

The Sudan conflict has left millions of children without basic healthcare.

The collapse of crucial vaccination and health outreach has meant disease outbreaks such as cholera and malaria have become deadly, with one in six children completely unprotected.

Save the Children and Gavi, the Vaccine Alliance are working together to deliver vaccinations and lifesaving healthcare to hundreds of remote villages right across the country.

This is a key example of Gavi's reform agenda, the Gavi Leap, building partnerships that can reach the world's most vulnerable children in the toughest settings with lifesaving vaccines.

In the first three months of 2025 we vaccinated 21,000 children who have never received a vaccine before. But more still needs to be done.
