• Healthy male and female volunteers, 18-60 years
• Seronegative for one or two of the applied vaccine strains (with antibody titres =1:16 detected in micro-HAI assay for influenza A/Brisbane/59/07(H1N1), A/Brisbane/10/07(H3N2) and/or B/Florida/04/06
• Low antibody titres (i.e. titres =1:64 detected in micro-HAI assay) for H1N1v
• Written informed consent to participate in this study
• For female volunteers of childbearing potential, provision of a history and current use of reliable contraceptive practices (hysterectomy or bilateral tubal ligation, oral or implanted contraceptive use, intrauterine device, barrier method plus spermicide, history of a single male partner with vasectomy, or a history of abstinence deemed credible by the investigator). Note: The provision of this history does NOT replace the requirement to perform, and obtain negative results in pregnancy tests.

- Primary Outcome Measures
Name Time Method Main Objective: To assess safety and tolerability of single dose of GHB16L2;Secondary Objective: To assess<br>- immunogenicity (HAI, MNA, SRH, IgA, Granzyme B T-cell response)<br>- pharmacokinetics (shedding);Primary end point(s): The primary end point is to assess the safety and tolerability of GHB16L2 administered as a single dose liquid nasal spray against influenza A (H1N1, H3N2) and B virus. For this purpose 80 healthy volunteers are planned to be included in a phase I/II study where a first group of 18 volunteers and consecutively a second group of 62 volunteers will be randomized in a ratio of 1:1 for verum or placebo in parallel. The second group of 62 will only be included after the safety observation period and an interim safety review for the first group of 18 has been completed.;Timepoint(s) of evaluation of this end point: End of study
- Secondary Outcome Measures
