General information about the trial
|
|||
Main objective of the trial |
To evaluate the safety and reactogenicity of GSK Biologicals’ 10-valent pneumococcal conjugate vaccine (Synflorix - 10Pn) vaccine when co-administered with Infanrix hexa (DTPa-HBV-IPV/Hib) vaccine as a 3-dose primary vaccination course at 2, 3 and 4 months of age, in terms of grade 3 solicited and unsolicited adverse events (AEs).
|
||
Protection of trial subjects |
All subjects were supervised closely for at least 30 minutes following vaccination with appropriate medical treatment readily available. Vaccines were administered by qualified and trained personnel. Vaccines were administered only to eligible subjects that had no contraindications to any components of the vaccines. Subjects were followed-up from the time the subject consents to participate in the study until she/he is discharged.
