Dr Ellie Barnes talks about her research on Hepatitis C and her work on a T cell vaccine. Hepatitis C virus is a global epidemic, affecting around 200 million people worldwide. Many chronically infected patients silently develop complications of liver disease that can include hepatocellular cancer, liver cirrhosis and liver failure. Unlike other vaccines, inducing antibody reactions to Hepatitis C is often ineffective because antibodies only target the outer surface of the virus. To combat this Dr Ellie Barnes is developing a new therapeutic vaccine for this damaging virus.
