Caitlin Jarrett


Research Fellow and Project Manager, the Vaccine Confidence Project at LSHTM


Caitlin’s research experience incorporates the application of interdisciplinary approaches to operational and strategic global health initiatives with an emphasis on evidence synthesis, and more recently, communications.

She started her health career in the UK in 2006 working in mental health (clinical and research) with the NHS and National Institute for Health Research and health promotion (social marketing-based approach to cervical screening amongst young women) with the University of Newcastle, before joining the Vaccine Confidence Project in 2010.

Between 2013-2016, she conducted systematic reviews, including evidence quality assessment (GRADE, qualitative tools), on public trust and strategies to address public confidence in immunisation for the WHO SAGE Working Group on Vaccine Hesitancy and the ECDC.

Between 2017-2021, Caitlin was based in Basel, Switzerland, working with the Health Systems Strengthening Unit at the Swiss Tropical and Public Health Institute on implementation research including a large-scale RCT on health information systems across three African countries (Nigeria, Côte d’Ivoire and Mozambique) and evaluations of a design thinking- based initiative to improve cardiovascular health in low-income urban populations (São Paulo, Brazil) and a social marketing effort to support HPV vaccination in Ethiopia.

Returning to the VCP in 2021, she has been supporting a global research team investigating the impact of misinformation on global security, including vaccine hesitancy. She holds a BA in Social Anthropology (University of Sydney, Australia), a BSc/PGDip in Psychology (Macquarie University, Australia) and a Master of Public Health (Imperial College, London).
