Solicited local symptoms assessed were pain, redness and swelling.

Solicited general symptoms assessed were drowsiness, fever, irritability and loss of appetite.

Unsolicited AEs = Any AE reported in addition to those solicited during the clinical study. Also any "solicited" symptom with onset outside the specified period of follow-up for solicited symptoms was reported as an unsolicited adverse event.

Ramy czasowe: Prior to and one month after the booster immunisation for the Synflorix/Infanrix primed Group and prior to the first dose and one month after Dose 2 in the Synflorix/Infanrix unprimed Group

Vaccine pneumococcal serotypes assessed were serotypes 1, 4, 5, 6B, 7F, 9V, 14, 18C, 19F and 23F.

Concentrations were expressed as geometric mean concentrations (GMCs) in microgram per millilitre (µg/mL).

Unsolicited AEs = Any AE (i.e. any untoward medical occurrence in a patient or clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product) reported in addition to those solicited during the clinical study. Also any "solicited" symptom with onset outside the specified period of follow-up for solicited symptoms was reported as an unsolicited adverse event.
Within 31 days (Days 0-30) after vaccination
Number of Subjects Reporting Serious Adverse Events (SAEs).
Ramy czasowe: During the entire study period, from the vaccination visit at Day 0 up to the end of the follow-up visit at Month 1 for the Synflorix/Infanrix primed Group and up to Month 3 for the Synflorix/Infanrix unprimed Group.
