Clinical Trial Summary

The primary aim of this study is to assess the reactogenicity of Synflorix vaccine and Prevenar 13 vaccine after primary vaccination at 2 and 4 months of age with either Synflorix or Prevenar 13 vaccine or Prevenar 13 and Synflorix, respectively. In addition, this study aims at assessing the safety, reactogenicity, immunogenicity and antibody persistence (approximately 8-11 months following primary vaccination) of the Synflorix vaccine and Prevenar 13 vaccine after primary vaccination at 2 and 4 months of age with either Synflorix or Prevenar 13 vaccine or Prevenar 13 and Synflorix, respectively. This study also aims at assessing the safety, reactogenicity and immunogenicity of the Synflorix vaccine when given as a booster dose at 12-15 months of age following primary vaccination at 2 and 4 months of age with either Synflorix vaccine or Prevenar 13 vaccine or Prevenar 13 and Synflorix respectively.

Description:

This study is partially blinded as the primary phase will be conducted in an observer-blind method and booster phase will be open method.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Subjects With Grade 3 Adverse Events (AEs) (Solicited and Unsolicited) - Primary Period	The number of subjects with Grade 3 AEs (solicited and unsolicited), during the 31-day post-vaccination period following each primary dose is reported.	Within 31-day (Day 0-Day 30) after any dose of primary vaccination
Secondary	Number of Subjects Reporting Any and Grade 3 Solicited Local Symptoms - Primary Period	Solicited local symptoms assessed include pain, redness and swelling. Grade 3 pain was defined as crying when limb was moved/spontaneously painful. Grade 3 swelling/redness was defined as swelling/redness larger than (>) 30 millimeters (mm). "Any" is defined as incidence of the specified symptom regardless of intensity.	During the 4-day (Days 0-3) post-vaccination period following each primary dose
Secondary	Number of Subjects Reporting Any and Grade 3 Solicited Local Symptoms - Booster Period	Solicited local symptoms assessed include pain, redness and swelling. Grade 3 pain was defined as crying when limb was moved/spontaneously painful. Grade 3 swelling/redness was defined as swelling/redness larger than (>) 30 millimeters (mm). "Any" is defined as incidence of the specified symptom regardless of intensity.	During the 4-day (Days 0-3) post-booster vaccination period
Secondary	Number of Subjects Reporting Any, Grade 3 and Related Solicited General Symptoms - Primary Period	Solicited general symptoms assessed include drowsiness, fever (defined as axillary temperature = 37.5°C), irritability, and loss of appetite. Grade 3 drowsiness was defined as drowsiness which prevented normal everyday activities. Grade 3 fever was defined as fever (axillary temperature) above (>) 39.5 degree Celsius (°C). Grade 3 irritability was defined as crying that could not be comforted/preventing normal activity. Grade 3 loss of appetite was defined as the subject not eating at all. "Any" is defined as incidence of the specified symptom regardless of intensity or relationship to study vaccination.	During the 4-day (Days 0-3) post-vaccination period following each primary dose
