Brief Summary

Approximately 216, and up to 270, healthy males and non-pregnant females, 18 to 49 years old, inclusive, will be enrolled over a 5-month period into this multicenter, randomized, double-blinded, controlled Phase I study. Subjects who meet the entry criteria for the study and provide informed consent will be randomized 2:1 between adjuvanted and unadjuvanted vaccine and placed into one of 6 groups (see table) to receive two doses of an intramuscular subvirion inactivated monovalent influenza A/H5N1 virus vaccine at 3.75, 7.5, or 15 mcg given with the adjuvant MF59 or diluent (N=216, up to 270). All eligible subjects will receive 2 doses separated by approximately 21 days.

Unresolved or continuing Grade 1 adverse events are permissible unless, in the opinion of the site principal investigator or appropriate sub-investigator, they would render vaccination unsafe, would interfere with the evaluation of responses or are not generally seen in "normal, healthy subjects".
• Grade 2 or greater severity clinical safety lab values (according to the toxicity table, Section 11.1.1.2) that do not return to Grade 1 or less prior to the second vaccination. If the clinical safety lab values return to Grade 1 or less, vaccination should be rescheduled within the acceptable window for the second vaccination - see Section 10.3.3. Subjects who experienced a Grade 3 or above clinical safety laboratory adverse event since receipt of Dose 1 should be excluded from receipt of second vaccination. Subjects who had a Grade 3 or above clinical safety laboratory adverse event prior to first vaccination will be evaluated by the site principal investigator and DMID Medical Monitor to determine receipt of second vaccination.
• Have an acute illness, including an oral temperature greater than or equal to 100.4 degrees Fahrenheit, within 3 days prior to the second vaccination. Vaccination of subjects should be deferred until acute illness, including an oral temperature greater than or equal to 100.4 degrees Fahrenheit, has resolved. If resolution occurs, vaccination should be rescheduled within the acceptable window for the second vaccination - see Section 10.3.3.
• Emergence of Grade 2 or greater severity signs or symptoms since receipt of Dose 1 that could confound or confuse assessment of vaccine reactogenicity.
• Any new clinical findings since receipt of Dose 1, which in the opinion of the site principal investigator or appropriate sub-investigator, would compromise the safety of the subject or would interfere with the evaluation of responses or successful completion of the study.
• Plan to travel outside the U.S. in the time between the second vaccination and 21 days following the second vaccination.
• Subject refuses further vaccination. Subjects who do not receive the second vaccination will be asked to return for safety assessments and for scheduled venous blood sample collections for clinical safety laboratory and immunogenicity evaluations and will be followed for the duration of the study - see the protocol-specific Manual of Procedures (MOP) for further details.
• Subject withdraws consent. The subject may withdraw their consent for study participation at any time and for any reason, without penalty.
