Number of Participants With Local and Systemic Adverse Events and Tolerability of Adjuvanted H1N1 Influenza Vaccine. [ Time Frame: 21 days after vaccination ] [ Designated as safety issue: Yes ]
Solicited adverse events were collected on side reactions form which were filled in for 21 days after pandemic or seasonal vaccination.
The primary endpoints of the trial are the local and systemic adverse events and tolerability of parenterally administered adjuvanted H1N1 influenza vaccine in all volunteers [ Time Frame: 2010 ] [ Designated as safety issue: Yes ]

Evaluation of the Immunogenicity of Adjuvanted H1N1 Influenza Vaccine Using Haemagglutination Inhibition Titres. [ Time Frame: 7, 14, 21 days post vaccination and long term follow up for 5 years ] [ Designated as safety issue: No ]
Antibody responses were measured using the HI assay to evaluate the rapidity and long term duration of the response
The secondary endpoints are the evaluation of the immunogenicity of adjuvanted H1N1 influenza vaccine and the ability of the vaccine to meet the CHMP evaluation criteria in a subset of volunteers [ Time Frame: 2011 ] [ Designated as safety issue: No ]

Safety and Immunogenicity Studies of Pandemic Influenza (H1N1) 2009 Vaccine in Bergen
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

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.
