Brief Summary
Groups 1 to 3 will receive two vaccinations on Day 0 and Day 21. Group 1 will receive 3.8µg A/H5N1 antigen formulated with AS03 adjuvant, administered by IM injection. Group 2 will receive 15µg A/H5N1 by IM alone. Group 3 will also receive 15µg A/H5N1 antigen administered IM but followed by the topical application of a VEP at the vaccination site. Group 4 will receive a single vaccination on Day 0 of 30µg A/H5N1antigen by IM, followed by application of a VEP at the vaccination site. The VEP (Vaccine Enhancement Patch) contains 50 mcg LT (heat-labile enterotoxin of E. coli)

Outcome Measures
Primary Outcomes (1)
Evaluate hemagglutination inhibition (HI) immune responses
Evaluate hemagglutination inhibition (HI) immune responses to two doses of 15μg A/H5N1 achieved in the antigen plus VEP group versus the antigen alone group (Group 3 vs. Group 2) at Day 42 using standard serological parameters (Geometric Mean Titer \[GMT\], Geometric Mean Fold Ratio \[GMFR\], seroconversion and seroprotection).
Day 42
Secondary Outcomes (2)
Safety of 15µg and 30µg IM A/H5N1 antigen administered with the 50µg VEP
8 months
Characterize HI immune responses
