NCT00776750

Brief Summary

Disturbances of acquired immunity are considered to be responsible, at least partly, for the high infection rate and inadequate response to vaccinations observed in hemodialysis (HD) patients and renal transplant recipient (RTR). The present prospective trial aims at (a) evaluating the immunogenicity of a standard influenza vaccine in HD and RTR patients and (b) at identifying determinants of the immune response.

Outcome Measures

Primary Outcomes (1)

  • Seroprotection rate, defined as the percentage of patients with an HI antibody titer ≥ 40,

Secondary Outcomes (1)

  • Seroresponse rate, defined as the percentage of patients with a fourfold rise in HI titer after vaccination; impact of booster vaccination on the immune response, and safety of influenza vaccination.

Study Arms (1)

influenza vaccination

EXPERIMENTAL

All participants received a standard dose of 0.5 ml commercially available trivalent split influenza vaccine (Vaxigrip®, Aventis Pasteur MSD) by intramuscular injection. The vaccine contained 15 μg hemagglutinin of each of the following influenza strains: A/ New Caledonia/20/99 (H1N1), A/ Panama/2007/99 (H3N2), and B/Shangdong/7/97, recommended by WHO as components of the influenza vaccine for the epidemic season 2003/2004.

Biological: trivalent split influenza vaccine

Interventions
