My research is centred around estimating and evaluating the impact of pneumococcal conjugate vaccines (PCV) on childhood disease burden through spatial and mathematical modelling. This involves characterising important factors of pneumococcal epidemiology such as local serotype distribution and vaccine coverage, as well as socio-economic and environmental determinants.
Currently, I am investigating pneumococcal epidemiology in China as part of the NIHR Evidence to Policy pathway to Immunisation in China (EPIC) project. This project aims to help decision-makers in China develop a vaccination programme that ensures reliable, affordable, equitable and uninterrupted supply of vaccines to the Chinese population.
I also work on a trial assessing the viability of reduced-dosage schedules of PCV in Nha Trang, Vietnam. Reduced-dose schedules, if effective, would increase the affordability of PCV for countries in the process of graduating from Gavi support.
