NCT01512056

Brief Summary

The purpose of this study is to evaluate the antibody response in dialysis patents to each of the three influenza vaccine strains included in the licensed seasonal flu vaccine (Formulation 2011-2012).

Outcome Measures

Primary Outcomes (1)

  • Change of antibody titer before and after influenza vaccination

    The primary endpoint will be the seroprotection rate which is defined as the proportion of subjects with HI titer ≥ 1:40. MicroNT-ELISA assay will also be used to evaluate the immune response post vaccination. The immune response based on microNT-ELISA antibody titers would be reported as antibody titer ≥1: 40 or ≥ 1:160 respectively because no threshold of protective NT antibody titer is clearly defined by the international guidelines.

    18 weeks

Secondary Outcomes (3)

  • Seroresponse rate

    0, 3 weeks, 6 weeks, 9 weeks and 18 weeks

  • Seroresponse rate

    0, 3 weeks, 6 weeks, 9 weeks and 18 weeks

  • the safety and tolerability profiles of the vaccine

    0, 3 week, 6 weeks, 9 weeks, 18 weeks

Study Arms (2)

the immunogenicity profiles of the AdimFlu-S

EXPERIMENTAL

Experimental group: to receive either only one dose of influenza vaccine at day 0 or one more booster vaccination 3 weeks later. Negative control group: dialysis patients who refused to receive influenza vaccination.

Drug: AdimFlu-S

The safety outcome of the vaccine

NO INTERVENTION

Any adverse effect, including systemic or local site, will be recorded during the study period.

Interventions

All enrolled participants will be divided into 3 groups: participants refused to receive vaccination, those receive either one (week 0) or one more booster vaccination (week 0 and week 3). Each dose of vaccine contains 15μg antigen of each virus strain suggested by WHO (A/California/7/2009 (H1N1);A/Perth/16/2009 (H3N2);B/Brisbane/60/2008).

  • An acute febrile illness within 1 week prior to vaccination;
  • Current upper respiratory illness, including the common cold or nasal congestion within 72 hours;
  • Subjects with influenza-like illness as defined by the presence of fever (temperature ≥ 38°C) and at least two of the following four symptoms: headache, muscle/joint aches and pains (e.g. myalgia/arthralgia), sore throat and cough;
  • Female subjects who are pregnant during the study.
  • Patients who receive hemodialysis therapy less than 3 months.
  • Treatment with an investigational drug or device, or participation in a clinical study, within 3 months before consent;
  • Immunodeficiency, or under immunosuppressive treatment.
  • Receipt of any vaccine within 1 week prior to study vaccination or expected receipt between Visit 1 (study vaccination) and Visit 2 (final collection of blood samples);
  • Receipt of any blood products, including immunoglobulin in the prior 3 months;
  • Any severe illness needed to be hospitalization within three months.
  • Underlying condition in the investigators' opinion may interfere with evaluation of the vaccine.
