Arm && Interventions

Group	Intervention	Description
IPV Group	Poliorix	Healthy male or female subjects between, and including, 60 and 90 days of age at the time of the first vaccination, receive 3 doses of Poliorix at 2 (Study Day 0, Visit 1), 3 (Study Month 1, Visit 2) and 4 (Study Month 2, Visit 3) months of age, administered intramuscularly into the upper right side of the thigh.

Primary Outcome Measures

Name	Time	Method
Number of Subjects Reporting Solicited Local Symptoms	During the 4-day follow-up period after each dose of study vaccine.	Solicited local symptoms assessed were pain, redness and swelling. Any = occurrence of the symptom irrespective of intensity grade. Grade 3 pain = cried when limb was moved/spontaneously painful. Grade 3 redness/swelling = redness/swelling spreading beyond 30 millimetres (mm) of injection site.
Number of Subjects Reporting Serious Adverse Events (SAEs)	During the entire study period (from Dose 1 up to one month following last vaccine dose).	SAEs assessed included any untoward medical occurrence that resulted in death, was life-threatening, required hospitalization or prolongation of existing hospitalization, resulted in disability/incapacity or was a congenital anomaly/birth defect in the offspring of a study subject.
Number of Subjects Reporting Solicited General Symptoms	During the 4-day follow-up period after each dose of study vaccine.	Assessed solicited general symptoms were drowsiness, irritability, loss of appetite and fever \[defined as axillary temperature equal to or above (≥) 37.1 degrees Celsius (°C)\]. Any = occurrence of symptom regardless of intensity grade of relationship to vaccination. Grade 3 drowsiness = drowsiness that prevented normal activity. Grade 3 irritability = crying that could not be comforted/prevented normal activity. Grade 3 loss of appetite = subject did not eat at all. Grade 3 fever = fever above (\>) 39.0°C. Related = symptom assessed by the investigator as related to vaccination.
Number of Subjects Reporting Unsolicited Adverse Events (AEs)	During the 31-days follow-up period after each dose of the study vaccine.	Unsolicited AE covers any AE reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any = occurrence of any unsolicited symptom regardless of intensity grade or relation to vaccination.
