Brief Summary:

Measles is a vaccine-preventable disease, which can be life-threatening in immunosuppressed children. Currently, measles vaccine is not recommended in pediatric orthotopic liver transplant recipients, because it is a live-attenuated vaccine.

We want to assess the influence of immunosuppression on immunity against measles in previously vaccinated children and to evaluate the induction of B cell and T cell response against measles elicited by vaccination in children at least 12 months after transplantation.

Condition or disease Intervention/treatment Phase
Measles Biological: MMR vaccination Phase 4

Detailed Description:

Eligible children in Group 2 will receive a standard dose (0.5 ml) of MMR vaccine during the first medical visit (V1). The lot number and the expiration date will both be recorded on the patient's case report form (CRF). A serological evaluation 4-8 weeks after MMR will identify children requiring an additional dose given 1-2 months apart, as currently recommended for subjects 1 year-old or with limited immune competence (i.e. HIV-infected children). Serological evaluation 4-8 weeks after the second dose or at the one-year follow-up will identify eventual non-responder requiring a third dose. Three will be the maximal number of administrated dose according to this protocol. The persistence of measles-specific antibodies will be assessed yearly, when patients come for their routine visit to the transplant center.

Children who do not need MMR immunization because of protective levels will be monitored yearly for maintenance of antibody levels during routine yearly visits/ blood samplings and will not have further intervention.

Arm Intervention/treatment
Experimental: MMR vaccination
MMR vaccine to seronegative pediatric SOT recipients
Biological: MMR vaccination
Unprotected children will be vaccinated with two MMR vaccines

Primary Outcome Measures :
  1. serologic response to MMR vaccine in seronegative transplant recipients [ Time Frame: 2 months after vaccination ]
    Pediatric transplant recipients will be vaccinated with MMR vaccine (previously seronegative) and their seroresponse will be measured 2 months later

Secondary Outcome Measures :
  1. Persistance of seroresponse to MMR vaccine [ Time Frame: 3 years ]
    Seroresponse to MMR vaccine will be followed over time in pediatric transplant recipients

Other Outcome Measures:
  1. Efficacy of MMR vaccine in pediatric SOT recipients [ Time Frame: 3 years ]
    Protection against vaccine-preventable diseases will be assessed in pediatric SOT recipients
