The Tulip Challenge was initiated during the COVID lockdown period to encourage people to stay fit, be connected with the HLA family and united by the common goal: to enhance the outcome of transplantation.


Last May, 87 participants from 14 different countries have completed the Tulip Challenge. Thank you for sharing your photos and videos of unique, impressive and exhausting workouts, which will definitely inspire all of us for the future.

Together, we have raised €2175 which will be donated to the organizers of the 18th International HLA & Immunogenetics Workshop to support research on COVID-19. Next week, the cheque will be handed over to the chairmen Eric Spierings and Sebastiaan Heidt.
