Victoria Ewing is a Clinical Trial Manager of a trial (Add-Vacc) aiming to assess the impact of adding male HPV vaccination with one dose of HPV vaccine alongside the Tanzanian national HPV vaccination programme on the population prevalence of HPV vaccine genotypes in both males and females. In Tanzania, HPV vaccination is currently delivered to girls only. The Add-Vacc trial will measure the population prevalence of HPV in 18 to 21-year-old males and females before the added male vaccine dose, and three years later. This will help establish the impact of this one-off added dose in males. Victoria is also a Research Fellow in the Clinical Research Department of the London School of Hygiene and Tropical Medicine (LSHTM). She completed her MSc in Public Health in Developing Countries at LSHTM, before going on to complete her PhD in ‘Barriers and Enablers to Appropriate Malaria Treatment’, based at the Malawi-Liverpool-Wellcome Trust Clinical Research Programme, in Malawi. This research was nested within a large community-based cluster randomised clinical trial. She then returned to the UK where she worked as part of the Global Health Network, a project aimed at strengthening capacity to conduct clinical trial research in low- and middle-income countries, based at the Oxford Centre for Tropical Medicine and Global Health. She moved to Tanzania in 2016, where she spent several years coordinating a community-based health education project, before joining LSHTM and MITU to become a Clinical Trial Manager.
