Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to compare the body's reactions and immune responses after receiving different strengths of a H9N2 influenza virus vaccine with and without an adjuvant given into the arm muscle. Study participants will include up to 96 healthy adults, ages 18-34. The 4 dosages of the experimental H9N2 vaccine to be tested in this study are the following: 3.75, 7.5, 15, and 30-mcg (with and without MF59 adjuvant). Participants will be vaccinated on Days 0 and 28. Participants will record any vaccine side effects in a diary for 7 days following each vaccination. Participants will return to the clinic on days 2 and 7 after vaccination. Blood samples will be collected 7 days following each vaccination. Serum and nasal wash specimens will be collected before each vaccination and 4 weeks after injections (0, 4, and 8 weeks). Participants will be involved in study related procedures for up to 8 months.
