[The Conversation Africa] The hepatitis C virus, or HCV, causes a chronic liver infection that can lead to permanent liver scarring and, in dire cases, cancer. It affects around 71 million people worldwide and causes approximately 400,000 deaths each year. While treatments are available for HCV-related infections, they are expensive, hard to access and do not protect against reinfection. A vaccine that can help prevent HCV infection is a major unmet medical and public health need.
