However, subjects with hypertension (see \[1\] above) not associated with any heart condition will be excluded from participation in Cohort 3 of this study.~Exclusion Criteria:~The following exclusion criteria apply to subjects in all three cohorts:~Subjects will be excluded from participation in this study if they:~* Have a history of exposure to H5N1 virus or a history of vaccination with an H5N1 influenza vaccine;~* Are at high risk of contracting H5N1 influenza infection (e.g. poultry workers);~* Have a history of severe allergic reactions or anaphylaxis;~* Have a rash, dermatological condition or tattoos which may interfere with injection site reaction rating;~* Have donated blood or plasma within 30 days prior to study entry;~* Have received any live vaccine within 4 weeks or inactivated vaccine within 2 weeks prior to vaccination in this study;~* Have a known or suspected problem with alcohol or drug abuse;~* Were administered an investigational drug within 6 weeks prior to study entry or are concurrently participating in a clinical study that includes the administration of an investigational product;~* Are a member of the team conducting this study or are in a dependent relationship with one of the study team members. Dependent relationships include close relatives (i.e., children, partner/spouse, siblings, parents) as well as employees of the investigator or site personnel conducting the study;~* If female: are pregnant or lactating.~The following exclusion criteria apply to subjects in Cohort 1 only:~* Currently have or have a history of a significant neurological, cardiovascular, pulmonary (including asthma), hepatic, metabolic, rheumatic, autoimmune, hematological or renal disorder \[4\];~* Have any inherited or acquired immunodeficiency;~* Have a disease or are currently undergoing a form of treatment or were undergoing a form of treatment within 30 days prior to study entry that can be expected to influence immune response. Such treatment includes, but is not limited to, systemic or high dose inhaled (\>800µg/day of beclomethasone dipropionate or equivalent) corticosteroids, radiation treatment or other immunosuppressive or cytotoxic drugs;~* Have received a blood transfusion or immunoglobulins within 90 days prior to study entry;~* Have a functional or surgical asplenia.~(\[4\]) A significant disorder is defined as a disease or medical condition associated with impaired health status, increased risk for complications, requiring medical treatment and/or follow up.~The following exclusion criteria apply to subjects in Cohort 2 only:~* Are immune compromised due to stem cell or organ-transplantation with significant medical complications such as acute or chronic graft rejection or graft versus host disease requiring intensive immunosuppressive treatment, transplant failure or infectious complications or other conditions that would be considered a contraindication for vaccination with an inactivated vaccine.~* Are immune compromised due to HIV infection with a CD4 count of \< 200x10\^6/L at screening or significant medical complications such as opportunistic infections, malignant complications (e.g. lymphoma, Kaposi sarcoma), other organ manifestations consistent with advanced acquired immunodeficiency syndrome (AIDS) or other conditions that would be considered a contraindication for vaccination with an inactivated vaccine.~The following exclusion criterion applies to subjects in Cohort 3 only:~- Have a chronic cardiovascular, respiratory, renal, or metabolic (e.g. diabetes mellitus) illness with significant complications such as advanced heart failure, liver failure, renal failure, severe asthma or severe respiratory failure, infectious complications or other conditions that would be considered a contraindication for vaccination with an inactivated vaccine.

- Healthy Volunteers: t

Study Arms:
- Cohort 1, Treatment Arm 1 (Type: EXPERIMENTAL): Stratum A (18-59 ys)/B(\>=60 ys): 120 healthy volunteers per stratum will receive 2 vaccinations with 7.5 µg A/Vietnam/1203/2004 on Days 0 and 21 and participate in immunogenicity evaluation.~Among Stratum A volunteers, 60 will participate in antibody kinetics evaluation and 30 in cellular immunity evaluation.~Randomization to Treatment Arms 1 and 2 at 2:1 ratio. Subjects in Treatment Arm 1 will be included in the immunologic determination of lot-to-lot consistency.
- Cohort 1, Treatment Arm 2 (Type: EXPERIMENTAL): Stratum A (18-59 ys)/B(\>=60 ys): 60 healthy volunteers per stratum will receive 2 vaccinations with 3.75 µg A/Vietnam/1203/2004 on Days 0 and 21 and participate in immunogenicity evaluation.~Randomization to Treatment Arms 1 and 2 at 2:1 ratio.
- Cohort 1, Treatment Arm 3 (Type: EXPERIMENTAL): Stratum A (18-59 ys): 2060 healthy volunteers will receive 2 vaccinations with 7.5 µg A/Vietnam/1203/2004 on Days 0 and 21 and participate in safety evaluation only.~Randomization within Treatment Arms 3 and 4 at 1:1:1 ratio per study site to receive one of three different lots of the H5N1 influenza vaccine.
- Cohort 2, Treatment Arm 1 (Type: EXPERIMENTAL): 300 immune compromised individuals 18 years or older will receive 2 vaccinations with 7.5 µg A/Vietnam/1203/2004 on Days 0 and 21.~100 will participate in immunogenicity evaluation and 30 in cellular immunity evaluation.
- Cohort 3, Treatment Arm 1 (Type: EXPERIMENTAL): 300 chronically ill patients 18 years or older will receive 2 vaccinations with 7.5 µg A/Vietnam/1203/2004 on Days 0 and 21 and participate in immunogenicity evaluation.
- Cohort 1, Treatment Arm 4 (Type: EXPERIMENTAL): Stratum A (18-59): 540 healthy volunteers will receive 2 vaccinations with 7.5 µg A/Vietnam/1203/2004 on Days 0 and 21 and participate in immunogenicity assessment.~Randomization within Treatment Arms 3 and 4 at 1:1:1 ratio per study site to receive one of three different lots of the H5N1 influenza vaccine.~Subjects in Treatment Arm 4 will be included in the immunologic determination of lot-to-lot consistency.
