Journée mondiale du donneur de sang (fr)

Journée mondiale du donneur de sang is observed since 2005 on 14 June (the birthday of Karl Landsteiner, the creator of the ABO blood group system, for which he won the Nobel Prize).

The day dedicated to "thanking and celebrating voluntary non-remunerated blood donors".

One of the main goals of the World Blood Donor Day is to ensure the availability of 'safe blood' for transfusion.
