Efforts in minimizing risk of viral transmission through viral inactivation

The viral safety of blood and blood products has improved substantially over the last decade on account of the development of new viral screening and virucidal procedures. For nearly 15 years, virally inactivated blood derivatives, prepared by using advanced virucidal procedures, have amassed an extraordinary safety record with respect to hepatitis B and C and HIV. This record of safety has spawned the development of newer virucidal procedures designed to eliminate nonenveloped viruses from blood derivatives and viruses and other pathogens from blood components, including cellular components. Ongoing tests that include clinical studies will demonstrate how close we are to achieving a blood supply that is free of viruses, bacteria, and parasites.
