Researchers at Saint Louis University are seeking volunteers for 10-day stays at “Hotel Influenza,” the nickname for an unusual testing facility run by Saint Louis University. The facility is designed to give researchers a rare, controlled look at how viruses affect the human body. Participants will be getting paid close to $3,500 to be infected with a strain of influenza. Dr. Daniel Hoft, director of SLU’s Vaccine Center and principal investigator of an upcoming study, explains how the study will be conducted and the operation of SLU’s Extended Stay Research Unit.
