World Blood Donor Day takes place on June 14, 2021. The day is dedicated to "thanking and celebrating voluntary non-remunerated blood donors". It occurs on June 14, the birthday of Karl Landsteiner, the creator of the ABO blood group system, for which he won the Nobel Prize. The first day was held in 2005. One of the main goals of the World Blood Donor Day is to ensure the availability of 'safe blood' for transfusion.
Transfusion of blood and blood products helps save millions of lives every year. It can help patients suffering from life-threatening conditions live longer and with higher quality of life, and supports complex medical and surgical procedures. It also has an essential, life-saving role in maternal and perinatal care. However, in many countries, there is not an adequate supply of safe blood, and blood services face the challenge of making sufficient blood available, while also ensuring its quality and safety.
An adequate supply can only be assured through regular donations by voluntary unpaid blood donors. WHO’s goal is for all countries to obtain all their blood supplies from voluntary unpaid donors by 2020. Today, in just 62 countries, national blood supplies are based on close to 100% voluntary unpaid blood donations, with 40 countries still dependent on family donors and even paid donors.
