Number of Subjects With Any Solicited Local Symptoms
Assessed solicited local symptoms were pain, redness and swelling. Any = incidence of any particular symptom regardless of intensity grade.
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)
Number of Subjects With Solicited General Symptoms
Assessed solicited general symptoms were drowsiness, irritability/fussiness, loss of appetite and temperature \[defined as axillary temperature equal to or above 37.5 degrees Celsius (°C)\]. Any = incidence of any particular symptom regardless of intensity grade or relationship to study vaccination.
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)
Number of Subjects With 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.
