Brief Summary:
Evaluation of the immunogenicity and reactogenicity of two different formulations of commercially avail-able influenza vaccines in 4 different groups of immunocompromized outpatients (HIV positive patients, patients suffering from rheumatologic diseases and receiving treatment with immunosuppressive drugs and patients undergoing hemodialysis or continuous ambulatory peritoneal dialysis). The aim of the study was to investigate if the newest formulation of influenza vaccines (virosomal vaccines) offer a benefit in immunocompromized patients in comparison to an older subunit formulation.

Condition or disease Intervention/treatment Phase
Immunosuppression Biological: Virosomal influenza vaccine Biological: Subunit influenza vaccine Phase 4

Detailed Description:
The infection with influenza is associated with higher morbidity and mortality in risk groups including immunocompromized patients. The virosomal influenza vaccines have been associated with improved immunogenicity in former trials. No direct comparison with older formulations has been conducted so far.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 304 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Prevention
Official Title: Double Blind Randomized Comparison of a Subunit- and a Virosomal Influenza Vaccine in Immunocom-Promized Patients
Study Start Date : October 2005
Actual Primary Completion Date : July 2006

Primary Outcome Measures :
  1. Immunogenicity defined as seroconversion (1:>=4) and seroprotection rates (1:>=40) [ Time Frame: >60 Wochen ]

Secondary Outcome Measures :
  1. Reactogenicity in rheumatologic patients by disease specific scores [ Time Frame: Six weeks after vaccination ]
  2. Immediate side effects at time of application of vaccination [ Time Frame: Minutes after vaccination ]
  3. Side effects after vaccination [ Time Frame: First week after vaccination ]
