Safe blood supply improves as voluntary donations exceed 85%, but many people still lack access

New data from the World Health Organization (WHO) show sustained progress towards safer blood supplies globally but also highlight persistent inequalities in access to safe blood and weaknesses in governance, financing and regulation of blood systems. Data collected from 132 countries reveal that global blood collections increased by nearly 19% between 2013 and 2023. Voluntary, unpaid donors continued to drive this progress, accounting for over 85% of the estimated 120 million blood donations received in 2023. Despite these gains, access to safe blood and blood products remains highly unequal worldwide. Many patients – including women experiencing life-threatening bleeding during childbirth, children with severe anaemia, trauma or burn victims, patients undergoing surgery, and people living with conditions such as sickle-cell disease, thalassaemia, haemophilia, immune deficiencies and certain cancers – still lack reliable access to safe blood and life-saving transfusions, particularly in lower-income countries. "No one should die because safe blood is unavailable when it is needed," said Dr Tedros Adhanom Ghebreyesus, WHO Director-General. "These data show encouraging progress, particularly in the growing contribution of voluntary unpaid blood donors worldwide – the cornerstone of safe and sustainable blood supplies – but it also reminds us that where a person lives can still determine whether they have access to the blood transfusion they need. Governments must continue investing in strong, sustainable national blood systems and supporting the voluntary unpaid blood donors whose generosity saves millions of lives every year." Persistent inequalities in blood availability Although high-income countries account for just 15% of the global population, they collect 36% of all blood donations worldwide. In contrast, many lower-income countries continue to face blood supply shortages due to limited financing, weak infrastructure, logistical barriers and insufficient donor recruitment. Blood donation rates vary dramatically across countries, ranging from 0.4 to 53 donations per 1000 population. Twenty-four countries reported collecting fewer than 5 blood donations per 1000 population, reflecting severe constraints in providing timely transfusions for patients in need. The proportion of blood collected from voluntary, unpaid donors also differs considerably by income levels of countries. While such donations account for 98.4% of all blood donations in high-income countries, the figure falls to 63.4% in low-income countries, where health systems often struggle to maintain adequate and reliable blood supplies. Stronger governance and financing needed Safe blood depends on strong governance and regulation of blood systems, alongside sustained engagement and commitment of blood donors. WHO analysis shows that nearly one-third of countries still lack specific legislation to ensure the safety and quality of blood and blood products. Only 64% of countries report systems for regular inspection of blood services, 62% have licensing systems, and just 40% indicate that at least some blood transfusion services are accredited – highlighting significant gaps in quality assurance across the safe blood supply chain. Sustainable financing remains a major challenge. More than 1 in 7 countries reported having neither dedicated government budget allocations nor cost-recovery mechanisms for blood services, raising concerns about the long-term sustainability of national blood supplies. As part of efforts to build resilient and equitable health systems, WHO calls on countries and partners to strengthen governance and regulation of blood services, ensure sustainable financing, expand quality assurance programmes, improve clinical transfusion practices and strengthen surveillance and data systems to support evidence-based decision-making. These measures are essential to ensuring universal access to safe, effective and quality-assured blood and blood products, regardless of where people live. WHO is releasing this latest dataset, ahead of World Blood Donor Day, observed annually on 14 June. This year’s campaign, under the slogan “One Drop of Humanity. Give Blood. Save Lives,” recognizes the contribution of voluntary unpaid blood donors and highlights how every blood donation supports patients in need, strengthens communities and contributes to resilient health systems. Notes to editors The Global status report on blood safety and availability 2025 draws on data from 168 countries, covering 97% of the world’s population, and provides the most comprehensive global assessment of blood systems to date. It examines blood availability, transfusion safety, clinical use of blood, access to plasma-derived medicinal products and the capacity of national blood systems. Findings are based primarily on 2023 data reported by countries through the WHO Global Database on Blood Safety (GDBS).
