"A rare disease shouldn't mean fewer treatments"
Help fund research that gives families like Lilly-May's hope of new treatments for children born with a rare brain disease.
Funding vital research
We’re on a mission to save and change children’s lives through medical research, developing treatments, vaccinations and cures.
Fighting rare disease
30% of children with a rare disease will lose their lives before their fifth birthday. With your help we can develop treatments and cures to tackle rare diseases that devastate children’s lives. Help fund vital research.
Premature birth and pregnancy complications
Some women experience complications during pregnancy which can involve the mother’s health, the baby’s health or both.
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.
