Raregivers 100: Honoring Activists, Philanthropists & Policymakers Shaping the Future of Rare Disease Care

Why Advocacy and Policy Matter to Emotional Relief

When more than 350 million people worldwide live with rare diseases and fewer than 5% of over 10,000 rare conditions have approved treatments, progress cannot rely on medical innovation alone. The path forward also requires leaders who understand that sustainable care includes emotional support for caregivers, patients, and the professionals who serve them.

Activists raise awareness. Philanthropists provide resources. Policymakers shape systems. Together, they build the infrastructure that makes caregiver wellness not just possible, but prioritized.

The Raregivers 100 honors ten leaders whose work in advocacy, funding, and policy continues to transform how rare, chronic and complex disease communities access emotional support.

Nicola Blackwood

A leading voice in rare disease policy in the United Kingdom, Nicola Blackwood has helped shape healthcare frameworks that recognize caregivers as essential partners in treatment outcomes.

The Power of Recognition

These ten leaders represent different paths toward a shared goal: making rare disease caregiving visible, sustainable, and recognized as a global health priority. Their work shapes the ecosystem in which Raregivers operates, informing policy, directing funding, and changing how communities understand the emotional realities of rare disease.

Recognition is not promotion. It is an acknowledgment. It is our thank you to these individuals.

By honoring activists, philanthropists, and policymakers who are already leading, Raregivers recognizes the infrastructure builders whose work makes direct emotional support possible. Their influence reaches places most families never will, including legislative chambers, foundation boardrooms, policy discussions, and global health forums, carrying caregiver voices with them.

The Raregivers 100 reflects a simple truth caregivers have always known: emotional support is not optional. It is essential to sustainable care.
