The Development of Prophylactic and Therapeutic EBV Vaccines

Abstract

Over the last century, the development of effective vaccine approaches to treat a number of viral infections has provided the impetus for the continual development of vaccine platforms for other viral infections, including Epstein-Barr virus (EBV). The clinical manifestations associated with EBV infection occur either following primary infection, such as infectious mononucleosis, or following an extended period of latency, primarily the EBV-associated malignancies and potentially including a number of autoimmune disorders, such as multiple sclerosis. As a consequence, two independent vaccine approaches are under development to prevent or control EBV-associated diseases. The first approach, which has been widely successful against other viral infections, is aimed at inducing a viral neutralisation antibody response to prevent primary infection. The second approach focuses upon the induction of cell-mediated immunity to control latent infected cells in persistently infected individuals. Early clinical studies have offered some insight into the potential efficacy of both of these approaches.
