World Blood Donor Day: Solidarity, compassion and everyday superheroes
Established in 2004 by the World Health Organization (WHO), World Blood Donor Day is held on 14 June each year.

The theme for World Blood Donor Day 2026 is ‘One Drop of Humanity. Give Blood. Save Lives.’
Giving blood must rank among the most compassionate, humane and generous acts an individual can undertake. It can be literally lifesaving, making everyday superheroes of all those who donate their blood voluntarily. As the WHO says, “Each donation is more than a medical act: it is a powerful expression of solidarity, compassion and collective responsibility.”
Voluntary donation supports safety
Of course, the safety of donated blood – and any treatments derived from those donations – is paramount. We stand with all those who have suffered and continue to suffer from the impacts of contaminated blood, and with their families.
Today, blood transfusions and plasma-derived medicines are safer than ever. Alongside enhanced testing and blood safety systems, sustaining a supply of blood and blood products is underpinned by the goodwill and generosity of those who regularly volunteer to donate.
A lifeline for millions
The availability of donated blood means that millions of lives are saved by blood transfusions globally each year. At the same time, millions of people around the world living with rare and chronic conditions depend on treatments derived from blood components, including plasma.
In England, around two thirds of donated blood is used in the treatment of medical conditions such as trauma, surgery and cancer, and over 17,000 people rely on plasma-derived treatments.* These are people living with immune deficiencies, inflammatory and autoimmune diseases, amongst others – and people living with bleeding disorders.
While recombinant and non-factor replacement products are now available for people with haemophilia, the treatment landscape isn’t the same for those living with other rare and ultra-rare blood disorders. For some factor deficiencies, von Willebrand disease, Glanzmann thrombasthenia and others, plasma-derived treatments and blood products are a lifeline.
We thank all of you who have ever volunteered do donate blood (not just to get a cup of tea and a biscuit). We think you are all superheroes.
