Prof Peter Openshaw is a respiratory physician and mucosal immunologist, studying how the immune system both protects against infection but also causes disease. He has worked on RSV and influenza since the mid-1980s, leading a large Wellcome Trust funded consortium (‘MOSAIC’) to investigate the pathogenesis of human influenza in 2009-12. He was President of the British Society for Immunology (2013-18) and then Chair/vice-Chair or NERVTAG, a Department of Health committee horizon-scanning for emerging respiratory threats. He directed MRC/EU-funded studies of human volunteers infected with RSV and influenza and directs HIC-Vac, an international consortium that promotes the use of human challenge to accelerate vaccine development. He was Theme Lead for Respiratory and then Infection at Imperial's Biomedical Research Centre, now Head of Respiratory Infections Section Head within the National Heart and Lung Institute. He co-leads ISARIC4C, a UK-wide consortium established in 2020 to study the COVID-19 pandemic. He is an emeritus NIHR Senior Investigator.
