Clinical Trial Evaluating Efficacy and Safety of One Dose Versus Two Doses of Influenza Vaccination (TraNsgripe)

Randomized, Comparative and Prospective Clinical Trial Evaluating Efficacy and Safety of a Dose of Seasonal Flu Vaccine Compared to Two Doses of Vaccine for Prevention of Influenza in Solid Organ Transplant Recipients

Randomized, multicenter, open label trial to compare safety and efficacy of two doses stationary flu vaccination vs one doses in Solid Organ Transplant Recipients.

Intervention / Treatment

Detailed Description

The purposes of this study are:

  1. Evaluate the efficacy and safety of a double dose of seasonal flu vaccine compared to a single dose.
  2. Determine the specific cellular immune response produced after the first and second vaccine doses of seasonal flu vaccine by in vitro stimulation of specific memory cells (A and B flu viruses).
  3. Evaluate the humoral immune response produced after one dose vs two doses of seasonal flu vaccine by the measure of serum antibody levels.
  4. Evaluate clinical efficacy of stationary flu vaccine in solid organ transplant recipients.
  5. Evaluate a long term cellular and humoral response(1 year) of seasonal flu vaccine.
  6. Characterize the genetic expression profile of immune response after the flu vaccine in solid organ transplant recipients by means of a genetic sub-study.
  7. Characterize the flu vaccine effect (one dose and two doses) through the antibody anti-HLA(human leukocyte antigen), and its influence on the rejection rate in solid organ transplant recipients, by means of immunologic sub-study.

  • Interventional Model: PARALLEL
  • Masking: NONE

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Influenza vaccine, second administration after 5 weeks
Drug: Influenza vaccine (split virion, inactivated) suspension for injection 0.5ml at the baseline and 5 weeks after the first one.

Patients will be randomized at 1:1 rate and open label fashion, according to centers, and time elapsed since transplant and type of organ transplanted to one of this two interventions :

A arm (usual treatment): Influenza vaccine (split virion, inactivated) suspension for injection 0.5ml at the baseline.

B arm (experimental branch): Influenza vaccine (split virion, inactivated) suspension for injection 0.5ml at the baseline and 5 weeks after the first dose.

The follow-up of both arms will be at 5, 10 and 15 weeks and one year after the baseline.

Active Comparator: Influenza vaccine
Drug: Influenza vaccine (split virion, inactivated) suspension for injection 0.5ml at the baseline.

Patients will be randomized at 1:1 rate and open label fashion, according to centers, and time elapsed since transplant and type of organ transplanted to one of this two interventions :

A arm (usual treatment): Influenza vaccine (split virion, inactivated) suspension for injection 0.5ml at the baseline.

B arm (experimental branch): Influenza vaccine (split virion, inactivated) suspension for injection 0.5ml at the baseline and 5 weeks after the first dose.

The follow-up of both arms will be at 5, 10 and 15 weeks and one year after the baseline.
