Grade 3 pain = crying at limb movement/spontaneous pain.Grade 3 swelling = swelling extending on a surface higher than (\>) 30 millimeters (mm), for children between 1-5 years old; \> 50 mm for children between 6-12 years old and \>100 mm for children between 13-17 years old.
Solicited general symptoms assessed included: fatigue, fever \[defined as axillary temperature equal to or above (≥) 37.5 degrees Celsius (°C)\], gastrointestinal symptoms \[nausea, vomiting, diarrhoea and/or abdominal pain\], headache, drowsiness, irritability/fussiness and loss of appetite. Any = occurrence of the symptom regardless of intensity grade. Grade 3 fatigue/headache/drowsiness/gastrointestinal symptoms = fatigue/headache/drowsiness/gastrointestinal symptoms that prevented normal activity. Grade 3 fever = temperature \> 39.5°C. Grade 3 irritability/fussiness = crying that couldn't be comforted. Grade 3 loss of appetite = not eating at all. Related = symptom assessed by the investigator as related to the vaccination.

Solicited general symptoms, for this endpoint, were assessed in subjects aged 1-5 years, 6-12 years and 13-17 years. Symptoms with no values were not assessed for those specific age groups.
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. Unsolicited adverse events, for this endpoint, were assessed in all subjects, in both groups.
