Arms	Assigned Interventions
Experimental: Group A HAC1 Dose = 15ug; Alum Dose = 0	Biological: HAC1 Vaccine Subjects will come to the Clinical Trials Center up to 7 days prior to each vaccine dose to have blood drawn for research assays. The first dose of vaccine will be given on Day 0 and the second dose will be given 21 days later (± 3 days). Dose escalation will be staggered by at least 7 days as shown in Figure 1.

Detailed Description:

This is a single center, placebo-controlled, single blinded dose escalation study to preliminarily assess the safety, reactogenicity, and immunogenicity of different HAC1 vaccine formulations. This study will assess a novel HAC1 vaccine, which is plant derived. This vaccine will be compared to Placebo of normal (0.9%) saline, and reference vaccine consisting of an approved monovalent vaccine containing an A/California (H1N1)-like strain.

Subjects will receive 2 intramuscular injections of the experimental vaccine, placebo, or reference vaccine on Study Days 0 and 21
