Brief Summary

The purpose of this study is to assess the safety and immune response (body's defense against disease) to an experimental H1N1 influenza vaccine in healthy adult and elderly populations. The study will enroll up to 450 healthy adults ages 18 and older with no history of H1N1 infection or vaccination. Two hundred individuals will be 18-64 years old, and the other 200 will be greater than or equal to 65 years of age. Participants will be randomly assigned to 1 of 2 possible vaccine groups: group 1 will receive 15 micrograms (mcg) of H1N1 vaccine; group 2 will receive 30 mcg of H1N1 vaccine. Both groups will receive vaccine injections on days 0 and 21 in the arm muscle. Study procedures include: medical history, physical exam, maintaining a memory aid, and blood sample collection. Participants will be involved in study related procedures for approximately 7 months.

Outcome Measures

Primary Outcomes (17)

• Number of Participants Reporting Solicited Local Reactions Based on the Functional Grading Scale After the First Vaccination

  Participants maintained a memory aid to record daily the occurrence of local reactions of pain, tenderness and swelling for 8 days after vaccination (Day 0-7) based on their interference with daily activities, with a severity grade of mild meaning no interference, moderate as some interference and severe as significant interference/prevented daily activity. Participants are counted if they reported experiencing the symptom at any severity on any of the 8 days.

  Day 0-7 after first vaccination

• Number of Participants Reporting Solicited Local Reactions Based on the Functional Grading Scale After the Second Vaccination

  Participants maintained a memory aid to record daily the occurrence of local reactions of pain, tenderness and swelling for 8 days after vaccination (Day 0-7) based on their interference with daily activities, with a severity grade of mild meaning no interference, moderate as some interference and severe as significant interference/prevented daily activity. Participants are counted if they reported experiencing the symptom at any severity on any of the 8 days.

  Day 0-7 after second vaccination

• Number of Participants Reporting Measured Injection Site Reactions of Swelling and Redness After the First Vaccination
