Abstract: A process for inactivating viruses in blood and blood products in which a phenothiazine dye is added to the blood or blood product, and then irradiated with light. The use of a very small concentration of phenothiazine dye avoids any substantial adverse effects on the blood or blood products. Inactivation of the virus is effected by irradiation of the blood or blood product. After irradiation, the dye can be separated from the blood or blood product by a dye adsorbing agent.
