The correct answer is: World Blood Donor Day.
World Blood Donor Day is celebrated on June 14 every year to thank blood donors and raise awareness of the need for safe blood and blood products. The day was first established in 2004 by the World Health Organization (WHO) and the International Federation of Red Cross and Red Crescent Societies (IFRC).
The date of June 14 was chosen to commemorate the birthday of Karl Landsteiner, who was born on that day in 1868. Landsteiner was an Austrian physician and immunologist who is best known for his discovery of the ABO blood group system. His work on blood groups was instrumental in the development of blood transfusion, which has saved millions of lives.
World Blood Donor Day is celebrated around the world with a variety of events and activities. These events aim to raise awareness of the need for blood and blood products, to thank blood donors, and to encourage more people to donate blood.
Blood is a vital resource that is essential for saving lives. Every two seconds, someone in the world needs blood. Blood is used in a variety of medical procedures, including surgery, cancer treatment, and childbirth.
