Booster Vaccination Study with a Pneumococcal Vaccine in children primed with the same vaccine

A male or female between, and including, 12-18 months of age at the time of booster vaccination.

• Subjects for whom the investigator believes that their parent(s)/ guardian(s) can and will comply with the requirements of the protocol.
• Subjects who received three doses of pneumococcal conjugate vaccine in study NCT00680914.
• Written informed consent obtained from the parent(s)/guardian(s) of the child/ward.
• Healthy subjects as established by medical history and clinical examination before entering into the study.

Use of any investigational or non-registered product (drug or vaccine) within 30 days preceding the vaccination, or planned use during the study period.

• Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational product (pharmaceutical product or device).
• Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs within six months prior to vaccination.
• Administration of immunoglobulins and/or any blood products within three months preceding the vaccination or planned administration during the study period.
• Administration of any pneumococcal and/or Hib vaccine since the end of study NCT00680914.
• Planned administration/administration of a vaccine not allowed by the study protocol during the period starting 1 month (30 days) before the administration of the booster dose of the study vaccines (Visit 1) and up to the follow-up visit (Visit 2) with the exception of vaccines included in the Korean routine immunization which can be given at least one week before the administration of the study vaccines or after study end.
• Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.
• History of reactions or allergic disease likely to be exacerbated by any component of the study vaccines.
• Known hypersensitivity to any component of the study vaccines including anaphylactic reactions following the administration of the study vaccines.
• Major congenital defects or serious chronic illness.
• History of any neurologic disorders or seizures.
• Tympanic or axillary/ oral temperature >= 37.5°C or rectal temperature >= 38.0°C. A temperature greater than or equal to these cut-offs warrants deferral of the vaccination pending recovery of the subject.
