Professor Lalvani’s research programme addresses the world’s most serious respiratory infections: tuberculosis and pandemic influenza. His research has been published in over 120 scholarly articles and book chapters, with over 8,000 citations in the medical and scientific literature.CLINICAL AND PUBLIC HEALTH IMPACTClinical Practice: Professor Lalvani’s first translational research output, IGRA (T-SPOT.TB™) transformed clinical practice, shaped TB control policy internationally and provided health services with CDC and EuroCDC-endorsed rapid tools to cost-effectively deliver a TB elimination strategy through targeted preventative therapy of latent TB. Deployment of IGRA prevents diagnostic delays and unnecessary overtreatment - and is much preferred by patients.Policy and Guidelines: Having created the evidence-base underpinning the national and European guidelines endorsing IGRA (2006-2010), Professor Lalvani’s went on to develop a new evidence-based NICE-endorsed policy (2011) for immigrant TB screening which has set the new national clinical agenda on tackling TB in the EU.
