Number of Subjects With Any and Grade 3 Solicited Local SymptomsDuring the 4-day (Days 0-3) post-vaccination period following each vaccine dose and across dosesAssessed 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.
Number of Seroprotected Subjects Against Poliovirus Types 1, 2 and 3At Day 0, prior to the first vaccine doseA seroprotected subject was defined as a vaccinated subject with anti-poliovirus types 1, 2 and 3 titers ≥ 8 ED50.
Number of Subjects With Any Unsolicited Adverse Events (AEs)Within the 31-day (Days 0-30) post-vaccination periodAn 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.
Number of Subjects With Serious Adverse Events (SAEs)During the entire study period (from Day 0 to Month 3)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.
Number of Subjects With Any, Grade 3 and Related Solicited General SymptomsDuring the 4-day (Days 0-3) post-vaccination period following each vaccine dose and across dosesAssessed 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.

Recruitment details

Of the 1101 enrolled subjects, one subject was not randomised and administered any vaccine as the parents of the subject refused to vaccinate their child after blood collection at Visit 1 and withdrew their consent.

Pre-assignment details

During the screening the following steps occurred: check for inclusion/exclusion criteria, contraindications/precautions, medical history of the subjects and signing informed consent forms.

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).

Time frame: At Month 3, one month after the third vaccine dose

Population: The analysis was performed on the According-to-Protocol (ATP) cohort for immunogenicity, which included all evaluable subjects for whom data concerning immunogenicity outcome variables and assay results for antibodies against at least one study vaccine antigen component after vaccination were available.
