Today is the World Blood Donor Day.
This day, human blood groups were discovered. The Austrian physician and immunologist Karl Landsteiner received the Nobel Prize in 1930 for this invention.
We are very grateful to all those involved in this vital cause! Congratulations to transfusion physicians, volunteer donors, volunteers, and especially our longtime friends and partners, the Zdai Blood Donor Project for their weekly #HeartThursday campaign, which has given thousands of patients a chance for a happy life.
