What is WMDD?

This year, World Marrow Donor Day (WMDD) will be celebrated globally on Saturday, September 19. The event will be celebrated in more than 50 countries around the world reaching hundreds of thousands of people and resulting in a great deal of media coverage.

The event serves to thank voluntary, unpaid blood stem cell donors and bone marrow donors for their life-saving gifts of stem cells and also to raise awareness of the need for new stem cell donors to ensure that all patients in need of a transplant are able to find a match.

WMDD is organised by the World Marrow Donor Association. To inspire you, you can watch the movies of the previous editions. Click here.

Events around the world

 WMDD targets primarily the general public, but also seeks to raise awareness among policymakers, public authorities, industry representatives, researchers, health professionals and anyone who has a genuine interest in blood stem cell donation and blood stem cell transplantation.

This website includes information about WMDD events happening around the world, how to register an event and submit international donor/recipient stories.

All forms of participation for WMDD, big or small, are encouraged. Be creative and let your heart speak. Take thank you pictures with your team or donors and post them on social media or websites. WMDD would not be possible without the continuous efforts of organisations around the world, building awareness locally in order to achieve a potential donor for each patient.
