Further study details as provided by University of Bergen:

Primary Outcome Measures:
  • 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 ]

Secondary Outcome Measures:
  • 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 ]

Estimated Enrollment: 8000
Study Start Date: October 2009
Estimated Study Completion Date: December 2016
Primary Completion Date: January 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Pandemic influenza vaccine (H1N1)v Biological: Pandemrix

Vaccination Pandemrix suspension and emulsion for emulsion for injection. 1 dose (0.5 ml) contains Split influenza virus, inactivated, containing antigen 3.75 micrograms of A/California/7/2009 (H1N1)v-like strain (X-179A)

* Pandemic influenza vaccine (H1N1)v (split virion, inactivated, adjuvanted)

Other Name: Pandemic influenza vaccine (H1N1)v (split virion, inactivated, adjuvanted)

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.

Ages Eligible for Study:   19 Years to 70 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

Signed informed consent Subjects able to understand and comply with the study protocol and complete the Adverse Event Form Subjects able to attend the scheduled visits for the kinetic study

Exclusion Criteria:

  • Persons with a history of anaphylaxis or serious reactions to any vaccine
  • Person with known hypersensitivity to any of the vaccine components
  • Persons who have had a temperature >38oC during the previous 72 hours
  • Persons who have had an acute respiratory infection during the last 7 days
  • Suspected non-compliance
