Brief summary

The purpose of this study is to assess the immunogenicity in terms of antibody response and the safety/reactogenicity in terms of solicited and unsolicited symptoms and serious adverse events following primary vaccination of Indian infants with pneumococcal conjugate vaccine GSK1024850A co-administered with a diphtheria, tetanus, whole cell pertussis (DTPw)-combined vaccine during the first 4 months of life. The study will be conducted in India.

Number of Subjects With Opsonophagocytic Activity Against Pneumococcal Serotypes

Vaccine pneumococcal serotypes included 1, 4, 5, 6B, 7F, 9V, 14, 18C, 19F and 23F. Cross-reactive pneumococcal serotypes included 6A and 19A. Opsonophagocytic activity was defined as the dilution of serum (opsonic titer) able to sustain 50% killing of live pneumococci under the assay conditions. The cut-off of the assay was an opsonic titer equal to or greater than 8.

Time frame: One month after primary immunization (month 3)

Population: Analysis was performed on the According-to-Protocol cohort for immunogenicity, which included all evaluable subjects with available immunogenicity data.

Number of Subjects With Serious Adverse Events (SAEs)

SAEs assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization, result in disability/incapacity or are a congenital anomaly/birth defect in the offspring of a study subject.

Time frame: Following first vaccination (Month 0) throughout the entire study period (month 3)

Population: Analysis was performed on the Total Vaccinated cohort, which included all vaccinated subjects.

An AE is 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. Unsolicited AE covers any AE 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

Time frame: Within 31 days (day 0-30) after vaccination

Population: Analysis was performed on the Total Vaccinated cohort, which included all vaccinated subjects.
