The purpose of this study is to evaluate the reactogenicity, safety and immunogenicity of 2 doses of PED-HZ/su, GSK's vaccine candidate for the prevention of Herpes Zoster (HZ) in immunocompromised paediatric renal transplant recipients aged 1-17 years
Subjects' parent(s)/Legally Acceptable Representative(s) [LAR(s) who, in the opinion of the investigator, can and will comply, with the requirements of the protocol
Written or witnessed/thumb printed informed consent obtained from the parent(s)/LAR(s) of the subject prior to performance of any study specific procedure.
Written informed assent obtained from the subjects when applicable according to local requirements.
A male or female between, and including, 1 and 17 years of age at the time of randomisation (Visit Day 1)
Any primary kidney disease with a high incidence of recurrent primary kidney disease within the allograft
Evidence of recurrent primary kidney disease within the current allograft
Previous allograft loss secondary to recurrent primary kidney disease
History of more than one organ transplanted (that is, kidney-liver, simultaneous double kidney or kidney-other organ(s) transplanted).
Sequential
PED-HZ/su
Biological/VaccineGSK's candidate vaccine- PED-HZ/su. is administered intramuscularly in the deltoid of the non-dominant arm, on a two-dose schedule in the two investigational groups.
Number of subjects from the interventional groups, with solicited local adverse events (AEs)
Assessed solicited local AEs are pain, redness and swelling at the injection site. Pain includes tenderness. Note: GSK diary cards for collecting solicited local and general AEs/symptoms is different for subjects \< 6 years and ≥ 6 years. Hence the age category of 1-11 years is further split to 1-5 years and 6-11 years.
Number of subjects from the interventional groups, with solicited general AEs
Assessed solicited general AEs among Infants/Toddlers/Children \< 6 years are: * Drowsiness * Fever\* * Irritability/Fussiness * Loss of appetite * Gastrointestinal (GI) symptoms\*\* Assessed solicited general AEs among Children ≥ 6 years are: * Fatigue * Fever\* * GI symptoms\*\* * Headache * Myalgia * Shivering (chills) * Fever is defined as temperature ≥ 38.0°C/100.4°F \*\*GI symptoms include nausea, vomiting, diarrhoea, and/or abdominal pain Note: GSK diary cards for collecting solicited local and general AEs/symptoms is different for subjects \< 6 years and ≥ 6 years. Hence the age category of 1-11 years is further split to 1-5 years and 6-11 years.
Number of subjects from the control groups with solicited general symptoms
Assessed solicited general symptoms among Infants/Toddlers/Children \< 6 years are: * Drowsiness * Fever\* * Irritability/Fussiness * Loss of appetite * GI symptoms\*\* Assessed solicited general symptoms among Children ≥ 6 years are: * Fatigue * Fever\* * GI symptoms\*\* * Headache * Myalgia * Shivering (chills) * Fever is defined as temperature ≥ 38.0°C/100.4°F \*\*GI symptoms include nausea, vomiting, diarrhoea, and/or abdominal pain As subjects from the control group are not vaccinated, they will not complete the diary card for local solicited symptoms.
Number of subjects from the control groups with solicited general symptoms
Assessed solicited general symptoms among Infants/Toddlers/Children \< 6 years are: * Drowsiness * Fever\* * Irritability/Fussiness * Loss of appetite * GI symptoms\*\* Assessed solicited general symptoms among Children ≥ 6 years are: * Fatigue * Fever\* * GI symptoms\*\* * Headache * Myalgia * Shivering (chills) * Fever is defined as temperature ≥ 38.0°C/100.4°F \*\*GI symptoms include nausea, vomiting, diarrhoea, and/or abdominal pain
Number of subjects with SAEs, pIMDs and biopsy confirmed renal allograft rejections from day 1 to month 13
An SAE is any untoward medical occurrence that results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization or results in disability/incapacity pIMDs are sub sets of Adverse events of special interest (AESIs) that include autoimmune disease and other inflammatory and/neurological disorders of interest, which may or may not have autoimmune aetiology. The renal allograft rejections are biopsy confirmed pathophysiological changes indicative of rejection. The rejection is graded for severity and extent of histologic inflammation and injury. This outcome measure is analysed during epoch 002 (day 1 to month 2) and during epoch 003 (month 2- month 13)
Occurrence of Herpes Zoster cases
HZ may present classically with a unilateral, dermatomal rash that is associated with pain, pruritus, allodynia or other altered sensation. In this population, disseminated HZ may occur and present with a generalized rash with systemic symptoms such as fever. All children enrolled in the trial have a history of primary VZV infection or vaccination and in the presence of immunosuppression, disseminated HZ cannot be distinguished clinically from varicella This outcome measure is analysed during epoch 002 (day 1 to month 2) and during epoch 003 (month 2- month 13)
Number of subjects from the interventional pooled age group with solicited local AEs
The pooled age group includes all subjects aged 1-17 years. The assessed local AEs solicited are: * Pain * Redness * Swelling Note: Pain includes tenderness.
Number of subjects from the interventional pooled age group with solicited general AEs
The pooled age group includes all subjects aged 1-17 years. The assessed solicited general AEs among Infants/Toddlers/Children \< 6 years are: * Drowsiness * Fever\* * Irritability/Fussiness * Loss of appetite * Gastrointestinal (GI) symptoms\*\* The assessed solicited general AEs among Children ≥ 6 years are: * Fatigue * Fever\* * GI symptoms\*\* * Headache * Myalgia * Shivering (chills) * Fever is defined as temperature ≥ 38.0°C/100.4°F \*\*GI symptoms include nausea, vomiting, diarrhoea, and/or abdominal pain
