World Blood Donor Day (WBDD) is celebrated by blood services worldwide and takes place every year on 14 June, marking Karl Landsteiner's birthday - the Nobel Prize winner who discovered the ABO blood group system. It is an opportunity to express gratitude to those who donate their blood in order to save lives, without expecting anything in return. This year's host is Argentina with the theme 'More blood. More life' with the World Health Organisation encouraging communities in every country to join the World Blood Donor Day campaign and 'Paint the world red'.
