1.Subjectsâ?? parent(s)/ LAR(s) who, in the opinion of the investigator, can and will comply, with the requirements of the protocol (e.g. completion of the diary cards, return for follow-up visits, with access to a consistent means of telephone contact, either residential land line or mobile).
2.Written or thumb printed informed consent (including audio-visual recording of consent process) obtained from the parent(s)/LAR(s) of the subject prior to performing any study specific procedure.
3.A male or female PCV-naïve child (toddler) between and including 12 and 23 months of age at the time of first dose vaccination. PCV-naïve toddlers are those who have not been previously vaccinated with any licensed or investigational pneumococcal vaccine.
4.Toddlers with an up-to-date minimal vaccination status for their age at the time of enrolment (â??minimalâ?? defined as single dose of BCG, 3 doses of OPV, DPT, and Hepatitis B, and single dose of Measles at the time of enrolment).
5.Healthy subjects as established by medical history and clinical examination before entering into the study.
6.Subjects that are negative for Human Immunodeficiency Virus (HIV), hepatitis B and hepatitis C to the best of parent(s)/LAR(s) knowledge
1.Child in care, defined as a child who has been placed under the control or protection of an agency, organisation, institution or entity by the courts, the government or a government body, acting in accordance with powers conferred on them by law or regulation. The definition of a child in care can include a child cared for by foster parents or living in a care home or institution, provided that the arrangement falls within the definition above. The definition of a child in care does not include a child who is adopted or has an appointed legal guardian.
2.Previous history of pneumococcal vaccination;
3.Evidence of previous or intercurrent Streptococcus pneumoniae infection.
4.Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine during the period starting 30 days before the administration of study vaccine (Day -29 to Day 0), or planned use during the study period.
5. Any medical condition that in the judgment of the investigator would make intramuscular injection unsafe.
6.Chronic administration (defined as more than 14 days in total) of immunosuppressants or other immune-modifying drugs during the period starting six months prior to the first vaccine dose. For corticosteroids, this will mean prednisone ï?³ 0.5 mg/kg/day, or equivalent. Inhaled and topical steroids are allowed.
7.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 vaccine/product (pharmaceutical product or device).
8.Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination (no laboratory testing required).
9.Family history of congenital or hereditary immunodeficiency.
10.History of allergic disease or history of a serious reaction to any prior vaccination or known hypersensitivity likely to be exacerbated by any component of the study vaccines.
11.Major congenital defects as judged by the PI.
12.History of any neurological disorders, meningitis or seizures.
13.Toddler who has had a sibling die of sudden infant death syndrome (SIDS) or die suddenly and without apparent other cause or preceding illness in the first year of life.
14.Toddler is a direct descendant (child or grand-child) of any person employed by the Sponsor, the Contract Research Organization (CRO) or the Study Site (including the PI and study site personnel).
15.Acute disease and/or fever at the time of vaccination.
o Fever is defined as the endogenous elevation of at least one measured body temperature of >= 38â?¦C (>= 100.4â?¦F).8
16.Acute or chronic, clinically significant pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined by physical examination.
17.Administration of immunoglobulins and/or any blood products during the period starting three months before the administration of study vaccine or planned administration during the study period.
18. Administration of long-acting immune-modifying drugs at any time during the study period.
19. Occurrence of any of the following adverse events after a previous administration of a diphtheria-tetanus-pertussis vaccine:
- collapse or shock-like state (hypotonic-hyporesponsive episode) within 48 hours of vaccination,
- convulsions with or
