Kinetics of Mucosal and Systemic Immune Responses to Intranasal Live Attenuated Influenza Vaccine (LAIV)

Imperial College Healthcare NHS Trust·interventional·Posted Oct 1, 2019·Updated Dec 6, 2021

In Brief

A clinical study evaluating Live attenuated influenza vaccine and Vehicle control for Influenza and Vaccine Virus Shedding. Completed, enrolled 48 participants across 1 site.

Detailed Summary

Intranasal live attenuated influenza vaccine (LAIV; trade name FluMist/Fluenz-Tetra, manufactured by AstraZeneca/Medimmune) is the standard influenza vaccine given to children aged 2-17 years of age in the UK. It is also licensed to be given to adults up to the age of 49 years in the USA. The systems biology of the human blood response to influenza vaccines has been studied in great detail, but there is a paramount need to study innate and specific, soluble and cellular immune responses at the nasal mucosal site of influenza infection. In this way this study aims to determine correlates of efficacy and vaccine take in serum and nasal mucosal lining fluid (MLF).
