Ian Feavers, PhD, is Head of the Division of Bacteriology at the NIBSC, UK. He studied for his PhD at the University of Newcastle upon Tyne, eventually moving to NIBSC after periods of postdoctoral research at the University of Sheffield and the Friedrich Miescher Institut in Basel. During the late 1990s, when new conjugate vaccines were being introduced, he headed the laboratory responsible for the control and standardisation of meningococcal and pneumococcal vaccines. Ian continues to oversee an active research programme on the molecular genetics and immunology of meningococcal and pneumococcal antigens. Because of his broad experience of bacterial vaccines and molecular biology, he has been closely involved with a number of meningococcal vaccine developments. He regularly contributes to WHO and EU guidelines, serves as one of NIBSC’s representatives on the Vaccine Working Party of the EMA, and is a member of the JCVI subgroup on meningococcal vaccines. Ian teaches on a number of vaccine related courses in the University of London and is a Visiting Professor at Imperial College.
