Every year on June 14, World Blood Donor Day is celebrated.
In May 2005, during the World Health Assembly, ministers of health around the world unanimously adopted a declaration of commitment and support for voluntary blood donation. In resolution WHA58.13, they decided to celebrate World Blood Donor Day on June 14 of each year, the date of which is timed to coincide with the birthday of Karl Landsteiner (1868-1943), an Austrian physician and immunologist, Nobel laureate who discovered human blood groups.
World Blood Donor Day is a special day celebrated in honor of non-remunerated blood donors. The purpose of this event is to raise awareness of the need for safe blood and blood products and, of course, to express gratitude to donors who voluntarily donate their blood to save lives.
