Vaccines are the most effective tool to prevent the outbreak of many dangerous diseases, including polio and measles. They are also one of the most cost-efficient public health interventions that exist and have helped to dramatically reduce child mortality rates over the last two decades.

And yet too many children, often those living in the poorest and most underserved communities, still lack access to the healthcare necessary to help them survive and thrive. The children who need life-saving vaccines the most, are the least likely to get them.

Reaching every child requires a chain of people – from donors to vaccinators – working in coordination, especially when the going gets tough. Across this chain, UNICEF is there: strengthening systems, building capacity and supporting innovation. Together we can ensure that no child dies from an illness we know how to prevent.

This photo series highlights the lengths to which health workers – always on the front lines – go to deliver vaccines to children in some of the hardest-to-reach places on the planet.
