Funding vital research

We’re on a mission to save and change children’s lives through medical research, developing treatments, vaccinations and cures.

Childhood cancers

In the UK almost 4,000 children and young people under 25 are diagnosed with cancer every year. We are funding research to try and improve the chances and treatment for children with brain tumours and cancer.

Successes

With the help of all our supporters we have played a significant role in many medical breakthroughs for 70 years, starting with the development of the first UK polio vaccines.
