Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Haukeland University Hospital has approximately 8000 employees many of whom will be in the front line to receive the pandemic A/H1N1 vaccine. We propose to conduct a safety and immunogenicity study in these subjects

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
