Study Endpoints

Primary Endpoints

Person Year Rate as Regards Subjects With Culture-confirmed IPD Due to Any of the 10 Pneumococcal Vaccine Serotypes. In Children Starting Vaccination Within 7 Months of Life and Assigned to a 3-dose Primary Vaccination Course.
Period of follow-up was any time after the administration of first vaccine dose till the end of the blinded invasive disease (ID) Follow-up period (The blinded ID Follow-up period lasted at least 30 months).

The PYAR (Person-Year Rate) as regards subjects with culture-confirmed invasive pneumococcal disease (IPD) due to any of the pneumococcal vaccine serotypes was tabulated (vaccine pneumococcal serotypes = serotypes 1, 4, 5, 6B, 7F, 9V, 14, 18C, 19F and 23F). PYAR was calculated as follows n (= number of subjects reported with a culture confirmed IPD) divided by T (= sum of follow-up period expressed in years) (per 1000) as well as the corresponding 95% confidence interval (CI), calculated as a 2-sided profile log-likelihood ratio 95% CI using a classical log linear Poisson regression with strata.

Subjects received the Synflorix (called also 10Pn-PD-DiT, 10Pn or GSK1024850A) vaccine according to a 3-dose primary vaccination schedule with an interval of at least 4 weeks between doses, followed by a booster dose of the same vaccine with an interval of preferably 6 months since the previous vaccine dose (minimum 4 months) (3+1 Infant Schedule). The vaccine was administered intramuscularly in the thigh.
