The campaign, which originally was held as a European event in Italy, Spain, France and Belgium, was expanded by the WMDA to a worldwide celebration in 2015.
The main objective of WMDD is to thank all donors worldwide. Unrelated donors, family donors, cord blood donors, donors who already have donated, and donors who are on the global registry waiting to donate. Secondary objective is to raise awareness among the general public and decision-makers about being a stem cell donor and the impact of blood stem cell transplantation on patients’ lives.
