Dr Hargreaves is leading a multi-disciplinary team focusing on rethinking approaches to the delivery of infectious diseases screening and catch-up vaccination to recently arrived migrants to the UK and European region, to ensure health systems are more responsive to their health needs. She is working with Public Health England to better engage under-immunised migrants in UK primary care, and to assess levels of under-immunisation and their role in outbreaks. Her work explores the barriers and facilitators to mainstream health care experienced by migrants, using participatory research methods. She has a specific interest in the health of international labour migrants, asylum seekers, refugees, and undocumented migrants.
