Number of Subjects With Any Solicited Local Symptoms [ Time Frame: During the 4-day (Days 0-3) post-vaccination period after each dose and across doses: Up to Month 2 (Infanrix Hexa 6-10-14 Group) or Month 4 (Infanrix Hexa 2-4-6 Group) ]
Assessed solicited local symptoms were pain, redness and swelling. Any = incidence of any particular symptom regardless of intensity grade.
Number of Subjects With Solicited General Symptoms [ Time Frame: During the 4-day (Days 0-3) post-vaccination period after each dose and across doses: Up to Month 2 (Infanrix Hexa 6-10-14 Group) or Month 4 (Infanrix Hexa 2-4-6 Group) ]
