Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to 1) demonstrate the protective efficacy against acute otitis media (AOM), 2) assess safety of the GlaxoSmithKline (GSK) Biologicals' pneumococcal vaccine GSK2189242A in Native American infants aged less than 24 months, living in the southwestern US, in and around the Navajo and White Mountain Apache reservations, and 3) evaluate the impact on acute lower respiratory tract infections (ALRI) up to the second year of life.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study will also evaluate the impact of the pneumococcal vaccine GSK2189242A on nasopharyngeal carriage in a subgroup of children called Carriage subgroup. Immunogenicity and reactogenicity of the pneumococcal vaccine GSK2189242A will be evaluated in another subgroup of children called Immuno/reacto subgroup.

Protocol Posting has been updated following Protocol Amendment 3, April 2012, leading to the addition of a secondary outcome measure.

Protocol Posting has been updated following Protocol Amendment 7, March 2017, to add serological testing for antibodies against the Hib polysaccharide PRP on samples collected 12 months following booster dose (Month 22) in the Immuno/reacto sub-cohort, in order to evaluate the long term persistence of immune responses to co-administered PedvaxHIB vaccine.

dPly-PhtD Group

Healthy Native American infants between, and including, 6 and 12 weeks (42-90 days) of age at the time of the first vaccination, receiving GSK2189242A (dPly-PhtD) vaccine co-administered with Prevenar13™: 3 primary doses at 2, 4, 6 months of age and a booster dose at 12-15 months of age.

PedvaxHIB was given as study vaccine to a subset of subjects at 2, 4 and 12-15 months.

At the primary epoch, the dPly-PhtD vaccine was administered intramuscularly into the right anterolateral thigh and at the booster epoch, the dPly-PhtD vaccine was administered into the right deltoid or anterolateral thigh if the deltoid muscle size was not adequate.

At the primary epoch, the co-administered Prevenar13™ and PedvaxHIB vaccines were administered intramuscularly into the left anterolateral thigh and at the booster epoch, the Prevenar13™ and PedvaxHIB vaccines were administered into the left deltoid or anterolateral thigh if the deltoid muscle size was not adequate.
