Number of Cases of Invasive Pneumococcal Disease (IPD) in Participants Less Than 5 Years of Age Due to Any Serotype Contained in 13vPnC
Zeitfenster: Baseline to 6 months after last vaccination
In order to assess the impact of 13vPnC on the incidence of IPD in the Yukon Kuskokwim (YK) Delta region, the Centers for Disease Control and Prevention (CDC) Arctic Investigation Program (AIP) accessed IPD data through evaluation of ongoing statewide IPD surveillance in Alaska. The CDC's AIP followed IPD (including serotype and vaccination history) to show whether identified cases of IPD received Prevnar, 13vPnC, or both. These data were combined with statewide data and used to identify the overall trend in IPD in the YK Delta region after introduction of 13vPnC.

Antibody geometric mean titers as measured by OPA assay for 13 pneumococcal serotypes (serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F). GMTs were calculated using all participants with available data for the specified blood draw. CIs for the GMTs are back transformations of confidence levels based on the Student t distribution for the mean logarithm of the titers.
28 to 56 days after vaccination 2 for Group 4, and after the single vaccination in Group 5.
Correlation of OPA and IgG Values for Each 13vPnC Serotype 1 Month After the Infant Series
Zeitfenster: 28 to 56 days after vaccination 3 for Group 1, after vaccination 2 for Group 2, and after vaccination 1 for Group 3.
28 to 56 days after vaccination 3 for Group 1, after vaccination 2 for Group 2, and after vaccination 1 for Group 3.
Correlation of OPA and IgG Values for Each 13vPnC Serotype 1 Month After the Toddler Dose
Zeitfenster: 28 to 56 days after vaccination 4 for Group 1, after vaccination 3 for Group 2, and after vaccination 2 for Group 3.
