Assess Reacto- and Immunogenicity of Pneumococcal Conjugate Vaccine When Given as Booster or a 2 Dose Catch up Schedule
Phase II, Observer-blind Follow-up Study to Assess reacto-and Immunogenicity of GSK Biologicals' Pneumococcal Conjugate Vaccine (GSK1024850A), When Given as Booster in Primed Children or as 2-dose Catch-up in Unprimed Children.
This is a booster study in 2 groups of healthy children less than 3 years old to measure the reactogenicity, safety and immunogenicity of GSK Biologicals' pneumococcal conjugate vaccine, when given as a booster or as a two-dose catch-up vaccination.
This protocol posting deals with objectives and outcome measures of the booster phase. The objectives and outcome measures of the primary phase are presented in a separate protocol posting (NCT number = NCT00338351).

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Subjects Reporting Grade 3 Symptoms (Solicited and Unsolicited)
Time Frame: Within 4 days after the administration of any study vaccine dose
|
Grade 3 symptoms are symptoms which prevent normal, everyday activities (e.g. in a young child such symptom would prevent attendance at school/ kindergarten/ a day-care center and would cause the parents/guardians to seek medical advice).
|
Within 4 days after the administration of any study vaccine dose
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Subjects Reporting Solicited Local Symptoms
Time Frame: Within 4 days after the administration of any study vaccine dose
|
Solicited local symptoms assessed include pain, redness and swelling.
|
Within 4 days after the administration of any study vaccine dose
|
Number of Subjects Reporting Solicited General Symptoms
Time Frame: Within 4 days after the administration of any study vaccine dose
|
Solicited general symptoms assessed include drowsiness, fever, irritability and loss of appetite. Fever was defined as rectal temperature ≥ 38 degrees Celsius. |
Within 4 days after the administration of any study vaccine dose
|
Number of Subjects Reporting Unsolicited Adverse Events
Time Frame: Within 31 days after the administration of any study vaccine dose
|
An Adverse Event is any untoward medical occurrence in a clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.
|
Within 31 days after the administration of any study vaccine dose
|
Number of Subjects Reporting Serious Adverse Events During the Active Phase of the Study
Time Frame: Throughout the active phase of the study ( from the beginning of the booster phase up to 1 month after the second booster dose)
|
A serious adverse event (SAE) is any untoward medical occurrence that: results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect in the offspring of a study subject, or may evolve into one of the outcomes listed above. |
Throughout the active phase of the study ( from the beginning of the booster phase up to 1 month after the second booster dose)
|
Number of Subjects Reporting Serious Adverse Events Throughout the Entire Study Period
Time Frame: Throughout the entire study period (from the beginning of the booster phase up to the end of the 6-month extended safety follow-up)
|
An SAE is any untoward medical occurrence that: results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect in the offspring of a study subject, or may evolve into one of the outcomes listed above. |
