Young EHA Best Abstract Awards

One of our primary missions is to support the future of hematology by nurturing young hematology clinicians and researchers.   

One way that we achieve this is through the Young EHA Best Abstract Award. 

Each year, the SPC allocates awards to the highest-ranking abstracts from:  

  • Clinicians or medical students training for a PhD degree 
  • PhD research students 
  • Postdoctoral fellows  
  • Clinical hematology trainees 

The award consists of free registration to the next Congress and €500 to cover expenses.   

Winners are given the opportunity to present their abstracts at Congress during a special session.    

You do not have to register or apply to be eligible for the award. The SPC and Advisory Board will make a selection based on the highest-ranking abstracts.
