Dr Kaja Abbas

Associate Professor

United Kingdom

My research area is vaccine impact modelling with a focus on estimating the health, economic, and equity impact of vaccination programmes to support evidence-based decision-making on vaccination strategies in collaboration with partners and stakeholders at the global, regional, and national levels. I have worked on impact assessment of existing and new vaccines to inform vaccine policy in varied contextual settings of low-, middle-, and high-income countries.

I hold a joint position with LSHTM and Nagasaki University. I welcome collaborations related to estimating vaccination impact in different geographic settings, and you are welcome to contact me.
