  Purpose

Severe Pneumococcal disease, such as bacteremia, meningitis and pneumonia, cause significant morbidity and mortality in both otherwise healthy adult population and in the immunocompromised patients. The incidence rate of invasive pneumococcal disease is considerably higher among organ transplant patients than in healthy individuals. Routine immunization with Pneumococcal vaccine is recommended pretransplant and once 3-5 years after the transplantation. The efficacy and immunogenicity of Pneumococcal polysaccharide vaccine(Pneumovax®) is suboptimal in this patient group. The conjugate Pneumococcal vaccine has been shown to be more immunogenic and safe in some other subgroups of immunocompromised patients. We intend to compare the immunogenicity of repeated dose 13-valent Pneumococcal conjugate vaccine (Prevenar13®)to the existing recommended protocol of Pneumococcal polysaccharide vaccine (Pneumovax®) in adult kidney and liver transplant patients.

Primary Outcome Measures:
  • Change from baseline serum serotype specific immunoglobulin G (IgG) antibodies to 13 polysaccharides and their opsonophagocytic activity (OPA) after the first vaccination [ Time Frame: baseline and 4 weeks after the first vaccination ] [ Designated as safety issue: No ]
  • Change from baseline serum serotype specific IgG antibodies to 13 polysaccharides and their opsonophagocytic activity (OPA) after the second Prevenar vaccination [ Time Frame: baseline and 4 weeks after the second vaccination ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • vaccination reactions [ Time Frame: from vaccination upto 1 week ] [ Designated as safety issue: Yes ]
    Questionaire and phone interview assessment of vaccination reactions and adverse effects.

  • rejection [ Time Frame: at 1 and 2 months after the vaccination ] [ Designated as safety issue: Yes ]
    Urine analyses and creatinine measurement with kidney transplant patients. Alanine aminotransferase measurement with liver transplant patients.

Estimated Study Completion Date: March 2017
Estimated Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Prevenar13
50 kidney transplant patients vaccinated with Prevenar13 as they enter the transplant waiting list. Pre- and postvaccination serotype specific ELISA and OPA measured. Revaccination at 6 months after the transplantation with Prevenar13, again pre- and postvaccination serotype specific ELISA and OPA measured
Biological: Prevenar13
Prevenar13 0.5ml injected intramuscularly (im.) at day 1 and at 6 months after the transplantation.
Active Comparator: Pneumovax
50 kidney transplant patients vaccinated with Pneumovax as they enter the transplant waiting list, serotype specific ELISA and OPA measured before and after the vaccination. At six and seven months after transplantation ELISA and OPA measured parallel to the experimental group
Biological: Pneumovax
0.5ml Pneumovax injected intramuscularly at day 1.
Experimental: liver Prevenar13
25 liver transplant patients vaccinated with Prevenar13 once they enter the transplant waiting list. Serotype specific ELISA and OPA measured before and after the vaccination. Revaccinated with Prevenar13 at 6 months after the transplantation. ELISa and OPA measured pre- and postvaccination.
Biological: Prevenar13
Prevenar13 0.5ml injected intramuscularly (im.) at day 1 and at 6 months after the transplantation.
Active Comparator: liver Pneumovax
25 liver transplant patients vaccinated with Pneumovax once they enter the transplant waiting list. Serotype specific ELISA and OPA measured pre- and postvaccination. At 6 and 7 months posttransplant ELISA and OPA measured parallel to the experimental group.
Biological: Pneumovax
0.5ml Pneumovax injected intramuscularly at day 1.
