Serum concentrations of anticapsular immunoglobulin G (IgG) and serum levels of opsonophagocytic activity (OPA) for the PCV13 pneumococcal serotypes
Brief summary
This is a PAC study after PCV13 launch in China. Based on recommendation from China Agency, Pfizer was required to conduct a descriptive immunogenicity study to measure the antibody levels at the time of disease onset.
Interventions
To test the serotype-specific IgG geometric mean concentration (GMC) and MOPA geometric mean titers (GMT) for each of the pneumococcal serotypes measured at the time of diagnosis of clinical pneumonia.

Blood must have been drawn from peripheral veins (eg, arm, foot, or scalp veins). Serum concentrations of anticapsular IgG were determined by enzyme-linked immunosorbent assay (ELISA) for each of the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) in all participants with a collected blood sample. |

GMTs of Pneumococcal MOPA by Cohort and VT Carriage Status - Subgroup Analysis
Approximately 5 mL of blood sample was collected within 24 hours of enrollment. Blood must have been drawn from peripheral veins (eg, arm, foot, or scalp veins). Serum levels of MOPA for each of the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) were determined in all 13vPnC cohort participants with adequate blood volume. In the Non-13vPnC cohort, a sample of participants with adequate blood volume was selected, to be equal to the number of the 13vPnC Cohort included for MOPA testing. For each cohort, participants were assigned to 2 subgroups: Participant in whom a 13vPnC VT strain had been isolated from the respiratory tract, and participant from whom a 13vPnC VT strain had not been isolated from the respiratory tract (VT carrier versus without VT carrier). Titer was expressed as reciprocal of the highest serum dilution.
Time frame: Day 1
Population: Analysis population for this OM included all participants who signed the informed consent document, met all inclusion/exclusion criteria, and had at least 1 immunogenicity assay value available for analysis. Overall number of participants analyzed indicates the number of participants in this analysis population. Number Analyzed in each row indicates the number of participants with valid and determinate assay results for the specified serotype.
