5. Study Description
Brief Summary
The purpose of this phase I/II trial is to evaluate safety and tolerability of a single dose of GHB16L2 administered by liquid nasal spray for vaccination against seasonal influenza virus infection. It is also performed to assess immunogenicity and pharmacokinetics (shedding).
Detailed Description
GHB16L2 intends to provide a novel vaccination for influenza virus infection. 80 healthy volunteers will be included at a ratio of 1:1 for GHB16L2 or placebo. GHB16L2 will be administered once on day 1. Follow-up visits will be performed on days 2, 8 and 29.
