Study Evaluating 13-valent Pneumococcal Conjugate Vaccine (13vPnC) in Children With Sickle Cell Disease

GMFR for the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) from 1 month after 13vPnC Dose 1 to 1 month after 13vPnC Dose 2 were computed using the logarithmically transformed assay results. Confidence interval (CI) for GMFR were back transformations of a CI based on the Student t distribution for the mean logarithm of the mean fold rise. GMFRs were calculated using all participants with available data from both 1 month after 13vPnC Dose 1 and after 13vPnC Dose 2 blood draws. Here number of participants analyzed signifies the evaluable immunogenicity population and "N" signifies participants with a determinate IgG antibody concentration for the given serotype at both 1 Month After 13vPnC Dose 1 and 1 Month After 13vPnC Dose 2 blood draws. Participants may be represented in more than 1 category.
