Detailed Description
The investigators will conduct a safety and immunogenicity study in health employees as detailed below:
- Examine adverse events of all employees after vaccination using adverse events form
- Examine the immunogenicity of the vaccine by collecting blood samples at days 0, 21 & 42 after vaccination (up to 500 people)
- Provide a detailed time course of the immune response to vaccination with a novel influenza H1N1 virus including the kinetics of the T-cell, B-cell and antibody responses in 50 volunteers
- Investigate the long lasting immunity induced by the vaccine
- Examine the ability of the vaccine to induce cross-reactive immunity to H1N1 strains.
