Eligibility Criteria
-----------------
Inclusion Criteria: A male or female infant between, and including, 60 and 90 days of age at the time of the first vaccination. Born after a gestation period of 36 to 42 weeks inclusive. Subjects who the investigator believes that their parent(s)/Legally Acceptable Representative (LAR) (s) can and will comply with the requirements of the protocol. Written informed consent obtained from the parent(s)/LAR(s) of the subject. Healthy subjects as established by medical history and clinical examination before entering into the study. Exclusion Criteria: Use of any investigational or non-registered product other than the study vaccine(s) within 30 days preceding the first dose of study vaccine, or planned use during the study period. Chronic administration of immunosuppressants or other immune-modifying drugs since birth. Administration of immunoglobulins and/or any blood products since birth or planned administration during the study period. Administration of a vaccine not foreseen by the study protocol within 30 days prior to vaccination, or planned administration during the study period, with exception of DTP, Hib and/or hepatitis B vaccine(s). Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational product. Evidence of previous or intercurrent poliomyelitis disease or vaccination. History of seizures or progressive neurological disease. Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination. History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccine(s). Major congenital defects or serious chronic illness. Child in care. The following condition is temporary or self-limiting, and a subject may be vaccinated once the condition has resolved and if no other exclusion criteria are met: • Current febrile illness or axillary temperature > 37.0 ºC or other moderate to severe illness within 24 hours of study vaccine administration.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Poliorix Group<br>Healthy male and female Chinese infants between, and including 60 and 90 days of age, who received 3 doses of Poliorix™ (IPV) vaccine at 2, 3 and 4 months of age, administered intramuscularly into the anterolateral side of the right thigh. | Biological: Poliorix™<br>* 3 doses, intramuscular administration<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Seroprotected Subjects Against Poliovirus Types 1, 2 and 3 | A seroprotected subject was defined as a vaccinated subject with anti-polio types 1, 2 and 3 titers greater than or equal to (≥) 8 effective dose 50 (ED50). | At Month 3, one month after the third vaccine dose | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Seroprotected Subjects Against Poliovirus Types 1, 2 and 3 | A seroprotected subject was defined as a vaccinated subject with anti-poliovirus types 1, 2 and 3 titers ≥ 8 ED50. | At Day 0, prior to the first vaccine dose | 
| Anti-poliovirus Types 1, 2 and 3 Antibody Titers | Antibody titers were presented as geometric mean titers (GMTs). | Prior to the first vaccine dose (Day 0) and one month after the third vaccine dose (Month 3) | 
| Number of Subjects With Any and Grade 3 Solicited Local Symptoms | Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of any local symptom regardless of intensity grade. Grade 3 pain = cried when limb was moved/spontaneously painful. Grade 3 redness/swelling = redness/swelling spreading beyond 30 millimeters (mm) of injection site. This outcome measure concerns subjects from the Poliorix Group only. | During the 4-day (Days 0-3) post-vaccination period following each vaccine dose and across doses | 
| Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms | Assessed solicited general symptoms were drowsiness, gastrointestinal symptoms, irritability/fussiness, loss of appetite and fever [defined as axillary temperature higher than (>) 37.0°C degrees Celsius]. Gastrointestinal symptoms included nausea, vomiting, diarrhoea and/or abdominal pain. Any = occurrence of any general symptom regardless of intensity grade or 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 gastrointestinal symptoms = gastrointestinal symptoms that prevented normal activity. Grade 3 fever= temperature > 39°C. Related = symptom assessed by the investigator as causally related to the vaccination. | During the 4-day (Days 0-3) post-vaccination period following each vaccine dose and across doses | 
| Number of Subjects With Any Unsolicited Adverse Events (AEs) | An unsolicited AE covers 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 and 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 was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination. | Within the 31-day (Days 0-30) post-vaccination period | 
| Number of Subjects With Serious Adverse Events (SAEs) | Serious adverse events (SAEs) assessed include medical occurrences that results in death, are life threatening, requires hospitalization or prolongation of hospitalization or results in disability/incapacity. | During the entire study period (from Day 0 to Month 3) |
