Reflection paper on viral safety of plasma-derived medicinal products with respect to Hepatitis E virus
Hepatitis E virus (HEV) is a causative agent of hepatitis in many countries and of emerging concern in industrialised countries. HEV is a non-enveloped, single-stranded, positive-sense RNA virus and a member of the family Hepeviridae. In developing countries, HEV (genotypes 1 and 2) is a major cause of acute hepatitis, transmitted by the faecal–oral route and associated with contamination of drinking water.

Draft reflection paper on viral safety of plasma-derived medicinal products with respect to hepatitis E virus
Hepatitis E virus (HEV) infection is widespread and blood/plasma donors are often asymptomatic. Therefore, there is a risk for viraemic blood donations. This raises questions about the safety of plasma-derived medicinal products. This reflection paper considers transfusion-associated infections and clinical experience with HEV-infections, HEV detection and epidemiology of HEV in blood/plasma donations, if serum antibodies against HEV significantly neutralise, studies on inactivation/removal of HEV during manufacture of plasma-derived products, and risk assessment for plasma-derived medical products.

Draft concept paper on viral safety of plasma-derived medicinal products with respect to hepatitis E virus
Viral safety of plasma-derived medicinal products needs to be kept under review as viruses are identified that can be present in the plasma starting material. Initiating action with a workshop will provide an effective means of bringing together and discussing the currently available information on this topic. This will then allow further actions to be identified.
