Study of the Ability of a Flu Vaccine to Prevent Flu Infection

January 25, 2007 updated by: PowderMed

A Prospective, Randomised, Double Blind, Placebo-Controlled Study to Assess the Efficacy of a Trivalent (A/New Caledonia/20/99, A/Panama/2007/99, B/Jiangsu/10/20) DNA Influenza Vaccine Administered by Particle Mediated Epidermal Delivery (PMED) Against a Controlled Influenza Virus Challenge.

The purpose of this study is to evaluate how effective the vaccine is at preventing subjects developing flu symptoms after they are directly exposed to flu virus. The study will also evaluate how well the vaccine is tolerated at sites where administrations are given, any effects it may have on subjects' wellbeing and whether it can produce antibody responses in the body

Detailed Description

Influenza is a contagious disease of the upper airways and the lungs. It rapidly spreads around the world in seasonal epidemics, killing hundreds of thousands of people and having high economic consequences due to healthcare costs and lost productivity. Each year governments recommend groups who are at risk of influenza or its complications to receive influenza vaccination. Current vaccine supply is not sufficient to meet the demand if this recommendation were to be taken up by all. This study will evaluate PowderMed's Particle Mediated Epidermal Delivery (PMED) DNA vaccine for influenza as a potential alternative to existing vaccine technologies. This study will assess how effective two different PMED vaccine combinations are at preventing subjects developing influenza following exposure to flu virus 56 days after a single dose of vaccine.
