Safety and Immunogenicity of Cell-culture Non-adjuvanted and MF59-adjuvanted Influenza H1N1 Vaccines in Healthy Adults
The purpose of this study is to evaluate the antibody response to one and two doses of influenza A/H1N1v vaccine in healthy adults.

Detailed Description
An observer-blind, single-centre study in which 7 groups of 25-30 male and female adults ≥18-50 years of age will be randomly allocated to receive two doses of cell culture non-adjuvanted or MF59-adjuvanted influenza A/California/4/2009 (H1N1) surface antigen vaccine containing 3.75, 7.5 or 15µg haemagglutinin by intramuscular injection.
A second dose of the same vaccine containing the same quantity of antigen as in the first dose will be administered 21 days later.
Three additional groups will receive two doses of MF59-adjuvanted influenza A/California/4/2009 (H1N1) surface antigen vaccine containing 7.5 µg haemagglutinin by intramuscular injection on day 0 or separated by 7 or 14 days.
Subjects will be observed for local and systemic reactions for 30 minutes after each immunisation and will be monitored for any reactions and other adverse events for 7 days after each immunisation.

- Individuals with a history of anaphylaxis or serious reactions to vaccines; hypersensitivity to influenzal viral protein, neomycin or polymixin, or products containing mercury.
- Persons with known immunosuppressive disease or who use systemic immunosuppressive drugs or other drugs listed in section 8 of the British National Formulary (BNF) or chloroquine, gold or penicillamine or other drugs listed in section 10.1.3 of the BNF to suppress a chronic disease process, or have received in the last 6 months radiotherapy or chemotherapy.
