Brief Summary

The purpose of the study is to evaluate safety and compare how the body reacts to 2 different strengths of the Clade (specific type of H5N1 virus) 2 H5N1 flu vaccine when given as a single vaccination with a high dose (90 mcg) or low dose (15 mcg) to volunteers who have received at least 2 doses of the Clade 1 H5N1 vaccine, in a previous National Institute of Health study or who have never received a H5N1 vaccine (naïve). Previously vaccinated subjects (in studies 04-0063, 05-0090, 05-0127) will receive either 15 or 90 mcg of H5N1 vaccine. Multiply boosted volunteers who participated study 05-0043 and received Clade 1 and 3 vaccines, will receive the same dose (15mcg). Vaccine naïve subjects will receive 2 doses of vaccine (15 or 90 mcg) separated by 28 days. Blood samples will be collected. 115 volunteers age 18-64 may participate in study related procedures for approximately 7 months.

Eligibility Criteria

• Age: 18 Years - 64 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• To participate in the primed group, the subject must have previously received at least 2 doses via the intramuscular route of subvirion inactivated A/H5N1/VN/1203/04 (H5N1) vaccine as part of a Division of Microbiology and Infectious Diseases (DMID)-sponsored protocol.
• To participate in the multiple boost group, the subjects must have previously received both clade 1 and clade 3 vaccines as a participant in the DMID 05-0043 study.
• To participate in the unprimed group, the subject must not have received previous H5N1 vaccine at any dose.
• The subject must be between the ages of 18 and 64 years, inclusive.
• Female subjects must fulfill one of the following: (i) not able to bear children because she has been surgically sterilized (tubal ligation or hysterectomy) for at least one year or is at least 1 year post-menopausal or (ii) agrees to practice effective methods of contraception that may include, but are not limited to abstinence, barrier methods, monogamous relationship with vasectomized partner, birth control pills, patches, hormonal shots or hormonal implants, NuvaRing and IUDs (intrauterine devices), from 30 days prior to study enrollment through 30 days following receipt of the last dose of vaccine.
• Female subjects of childbearing potential must have a negative pregnancy test (urine or serum) within 24 hours prior each to vaccination.
• The subject is able to understand and comply with the planned study procedures, including being available for all study visits.

• The subject has any condition that would, in the opinion of the site investigator, place the subject at an unacceptable risk of injury or render the subject unable to meet the requirements of the protocol.
• The subject has a diagnosis of schizophrenia, bi-polar disease, or other severe (disabling) chronic psychiatric diagnosis.
• The subject has been hospitalized within the past 5 years prior to enrollment for psychiatric illness, history of suicide attempt or confinement for danger to self or others.
